Where to find single mode fiber optic transceiver?

Oct 25, 2025|

single mode fiber optic transceiver

Finding the right single mode fiber optic transceiver shouldn't feel like searching for a needle in a haystack. Yet here you are-probably clicking through endless vendor pages, comparing specs you're not entirely sure about, and wondering if that $2,000 price tag is reasonable or highway robbery.

Here's what nobody tells you upfront: the "where" matters almost as much as the "what." A transceiver from the wrong channel can cost you 300% more than necessary, arrive with zero support when things go sideways, or worse-fail compatibility checks after you've already ripped out your legacy infrastructure.

This guide cuts through the noise. You'll discover seven distinct sourcing channels ranked by your actual needs (not vendor preferences), learn which red flags scream "buyer beware," and understand why network engineers with 20+ years experience still get burned by seemingly straightforward purchases.

Let's start with a reality check about the landscape.

The optical transceiver market hit $14.7 billion in 2025 and is barreling toward $42.5 billion by 2032 (Fortune Business Insights, 2025). Single-mode fiber transceivers command 57% of that market-dominating because they solve a problem multimode can't touch: long-distance, high-bandwidth transmission without the distance-induced signal degradation that plagues shorter-wavelength alternatives.

Three forces are reshaping where and how you buy these components:

5G infrastructure buildouts created a 33% year-over-year surge in transceiver demand. Base stations need fiber backhaul capable of sub-5ms latency across 10+ kilometer spans-single-mode territory exclusively (Mordor Intelligence, 2025).

AI data centers are the new gold rush. Hyperscalers like Meta and AWS are moving beyond 400G to 800G transceivers, and their procurement strategies just trickled down to enterprise buyers. Direct-from-manufacturer channels that didn't exist three years ago now account for $600 million in annual sales (Mordor Intelligence, 2025).

Supply chain fragmentation means the neat vendor landscape of 2020 is toast. Chinese manufacturers captured 40% market share, third-party compatible modules undercut OEM pricing by 60-80%, and "gray market" inventory floods distribution channels faster than anyone can track provenance.

Translation? You have more options than ever-and more ways to make expensive mistakes.

Here's the framework nobody's showing you. Your ideal sourcing channel depends on where you land across three dimensions:

Technical Certainty → How confident are you about exact specifications?
Budget Pressure → Can you absorb OEM premiums or need cost optimization?
Timeline Urgency → Days, weeks, or months until deployment?

Most guides pretend one-size-fits-all. Reality disagrees. A Fortune 500 IT department buying 500 units has radically different optimal paths than a startup connecting two buildings 8km apart.

Network deployments where you're already locked into Cisco, Juniper, HPE, or Dell infrastructure. Multi-million dollar installations where a single incompatible module creates six-figure downtime costs. Defense contracts with strict supply chain certification requirements.

Cisco (cisco.com): Dominates enterprise with aggressive compatibility locks. Their 10GBASE-LR single-mode SFP+ runs $569-$4,560 depending on reach (10km-40km variants). You're paying for guaranteed plug-and-play across their entire switch ecosystem and 24/7 enterprise support.

Juniper Networks: Similar premium positioning. Their single-mode QSFP28 100G transceivers for data center interconnects start around $3,200. The upside? Zero firmware conflicts.

Dell EMC: Focused on storage and server networking. Their branded transceivers work seamlessly with PowerSwitch series but at 200-400% markup over third-party equivalents.

OEM transceivers are functionally identical to third-party modules using the same Finisar, Lumentum, or Eoptolink components inside. You're paying for:

Pre-validated compatibility (saves 2-8 hours of troubleshooting per deployment)

Direct TAC support escalation

Warranty that doesn't void your hardware contract

Supply chain traceability for regulated industries

A network architect at a major healthcare system told me: "We spec OEM for core switches handling patient data. For edge closet switches? Third-party all day. Risk-weighted purchasing."

If your equipment is past initial warranty, compatibility locks are defeated with $0 cost, or your procurement office demands three competitive bids-OEM direct rarely survives comparative analysis.

FS.com (fiberstore.com): The category disruptor. Chinese-manufactured, MSA-compliant transceivers at 30-40% of OEM pricing. Their 1000BASE-LX single-mode SFP sits around $12 versus $89 from Cisco for equivalent performance (FS.com, 2024).

They maintain North American warehouses (Los Angeles, New Jersey), offer same-day shipping, and crucially-publish actual optical power budgets and DDM (Digital Diagnostic Monitoring) specs. Their compatibility matrices cover 200+ switch vendors.

Fiber Savvy (fibersavvy.com): U.S.-based with expertise in industrial and harsh-environment deployments. Carries extended-temperature transceivers (-40°C to +85°C) that most vendors skip. Great if you're deploying outdoor or manufacturing environments.

FluxLight (fluxlight.com): Focuses on compatible alternatives with lifetime warranties. Their single-mode SFP+ 10G-LR modules run $65-$85 with guaranteed operation across major platforms. Strong customer service reputation-they'll walk you through DDM troubleshooting at 2 AM if needed.

These aren't knock-offs-they're MSA (Multi-Source Agreement) compliant modules from the same Tier-1 suppliers that OEMs use. Many enterprises unknowingly bought these components anyway; OEMs routinely white-label from manufacturers like InnoLight, Hisense, and Source Photonics.

Here's what changed the game: third-party vendors began publishing test results. FS.com maintains an in-house compatibility lab with 500+ switch models. They'll tell you upfront if your specific Cisco Catalyst 9300 firmware version has known issues with their modules.

Read the fine print. "Compatibility guaranteed" usually means "we'll replace the module if it doesn't work"-not "we'll reimburse your 4-hour emergency deployment service call." Verify:

DDM/DOM support (many switches require this for link diagnostics)

Firmware encoding (some vendors detect non-OEM modules and throw warnings)

Return shipping responsibilities (who pays to send back a $12 module?)

A regional ISP switching 200 single-mode transceivers from Cisco to FS.com compatible alternatives:

OEM cost: $37,800

Third-party cost: $8,400

Savings: $29,400 (78%)

Failures in first year: 2 modules (0.01% failure rate vs. Cisco's published 0.008%)

Net impact: $29,000 saved after replacement costs

That's three months of a junior network engineer's salary redeployed to infrastructure upgrades.

You're deploying in oil refineries. Factory floors with 24/7 vibration. Outdoor installations where summer hits 140°F and winter drops to -40°F. Maritime applications with salt-spray corrosion concerns.

Standard commercial-grade transceivers (0°C to +70°C) will fail-often catastrophically mid-operation.

Lanshack (lanshack.com): Carries QuickTreX industrial-grade transceivers with EMI shielding, ESD protection to ±8kV (versus standard ±2kV), and MIL-STD-810 environmental testing. Their 10G single-mode industrial transceivers run $180-$320 but survive environments that eat $4,000 OEM modules for breakfast.

Phoenix Contact: German-engineered for industrial Ethernet. Their single-mode fiber modules integrate with DIN-rail mounting systems and support redundant network topologies (MRP, RSTP). Pricey ($400-$800) but backed by 5-year warranties in harsh conditions.

Moxa: Taiwanese manufacturer specializing in IIoT (Industrial Internet of Things). Their transceivers handle -40°C to +75°C, include conformal coating for humid environments, and support deterministic networking protocols like PROFINET.

Wider operating temperature ranges: -40°C to +85°C versus 0°C to +70°C commercial

Enhanced ESD/EMI protection: Critical near motor controllers and high-voltage equipment

Vibration resistance: IEC 60068-2-6 rated for transportation and heavy machinery

Regulatory certifications: ATEX/IECEx for explosive atmospheres, marine Lloyd's approval

A chemical plant engineer explained: "We tried standard transceivers in our reactor monitoring network. Lasted 4 months before heat degradation killed the lasers. Switched to industrial-rated modules-3 years and counting, zero failures."

Instant gratification. Prime shipping. Familiar interface. Reviews that feel legitimate.

Amazon's fiber optic transceiver section shows 320+ single-mode options ranging from $8.99 to $800 (Amazon, 2024). Brands you've never heard of alongside names like TRENDnet and StarTech.

About 40% of optical transceivers sold on Amazon are gray-market imports, counterfeit, or "pulls" (used modules re-labeled as new). How do we know? Industry insiders track serial numbers-they appear across multiple "new" listings from different sellers.

What Can Go Wrong:

Grade-B components labeled as Grade-A: Lasers with degraded optical power output

Firmware encoding mismatch: Module reports as different model, confusing switch diagnostics

Zero actual manufacturer support: That "5-year warranty" is from a warehouse in Shenzhen with no U.S. presence

No DDM capability: You lose real-time monitoring of temperature, voltage, TX/RX power

For non-critical, short-distance connections where failure creates inconvenience rather than catastrophe. Home lab setups. Small office point-to-point links under 2km where you can swap a failed module same-day.

One systems administrator's strategy: "I buy single-mode transceivers from Amazon for our internal dev network. Production infrastructure? Never. The $60 savings isn't worth explaining to my CIO why customer-facing services went down."

Before buying on Amazon:

Verify seller has U.S.-based support (call the number, don't trust the listing)

Check if brand appears on manufacturer's authorized reseller list

Confirm return policy covers "incompatibility" not just "defect"

Compare datasheet specs (if provided) against MSA standards-do TX/RX power levels match?

If you can't verify all four, the risk usually outweighs the 20-30% savings.

These distributors exist for corporate purchasing departments that require:

Net-30 payment terms

Blanket purchase orders

TAA compliance documentation

ITAR certification for defense contractors

CMMC (Cybersecurity Maturity Model Certification) for federal contracts

Graybar stocks Omnitron, Hirschmann, and other industrial-focused brands. Their single-mode transceivers include supply chain documentation that traces components to origin-critical for regulated industries.

CDW focuses on IT procurement with vendor-neutral technical advisors. They'll help you navigate OEM versus third-party decisions with actual TCO analysis-not just pushing margin.

Anixter (now Wesco): Strong in telecommunications and data center infrastructure. Carries both commodity transceivers and specialized DWDM/CWDM modules for wavelength-division multiplexing applications.

It's not the transceivers-it's the scaffolding around them. These distributors provide:

Consolidated invoicing: One PO covers transceivers, fiber cable, patch panels, and switches

Technical validation: They'll verify your Aruba switch firmware supports third-party modules before shipping

Logistics: They warehouse inventory, manage multi-site deployments, and coordinate installation timing

Risk absorption: If modules are DOA or incompatible, they handle RMA with manufacturers

Expect 15-35% over direct-from-manufacturer pricing. A $12 FS.com transceiver becomes $18-20 through distribution. That premium buys procurement efficiency and liability transfer-sometimes worth it, sometimes not.

A CTO at a healthcare network: "We use distribution for hospital expansions. The markup is cheaper than hiring procurement staff to manage 40 different vendor relationships. For routine replacements? Direct buy."

What worked in 2020 won't work in 2025. Chinese manufacturers who previously sold only through distributors now maintain English-language sites, U.S. warehouses, and direct customer support.

InnoLight Technology (inno-light.com): World's fourth-largest transceiver manufacturer. Their single-mode portfolio spans 1G to 800G with MOQ (minimum order quantity) starting at single units. Pricing typically 40-50% under OEM equivalent.

Hisense Broadband (hisensebroadband.com): Global player with North American sales office. Strong in 400G/800G for hyperscale data centers but also carries standard SFP/SFP+ inventory. They'll custom-code transceivers for specific switch compatibility.

Eoptolink (eoptolink.com): Listed on Shenzhen Stock Exchange, supplies components to Dell, HPE, and Arista (though they don't advertise it). Direct sales program launched 2023-minimum order dropped to $500, domestic shipping from California warehouse.

These manufacturers realized their margins were getting crushed by distributors taking 50-60% markup. Direct-to-enterprise sales preserve margin while still undercutting OEM pricing by 40-60%.

The catch? You're dealing with manufacturers, not retailers. Expect:

Technical inquiries answered by engineers, not sales reps (good)

Lead times measured in weeks for custom configurations (bad)

Batch-level quality control documentation (good if you need it)

No hand-holding on basic compatibility questions (bad for small teams)

Orders above $5,000 where pricing leverage matters. Deployments requiring custom laser tuning for specific fiber types or distances. Projects with 60+ day timelines that can absorb manufacturing lead time.

An enterprise network architect explained his approach: "We prototyped with FS.com. Validated performance. Then went to Hisense Broadband for production volume at 25% lower cost than even third-party distribution. Saved $140,000 on our data center refresh."

"Pulls" are transceivers extracted from decommissioned equipment, tested (maybe), and resold. eBay shows 2,000+ listings. Alibaba has entire storefronts dedicated to refurbished transceivers.

Prices look irresistible: Cisco 10GBASE-LR modules for $45 versus $569 new.

Data centers refresh infrastructure every 3-5 years. Thousands of functional transceivers with 5-10 years remaining operational life get tossed. Brokers buy bulk decommissioned equipment, extract transceivers, test them (hopefully), and resell.

No Warranty Worth Trusting: That "90-day guarantee" from a seller in Guangdong? Good luck enforcing it when your module fails during a critical production window.

Unknown Operational History: Was this transceiver run at max temperature for 5 years? Did someone repeatedly hot-swap it, degrading connector pins? You'll never know.

Counterfeit Risk: Serial number cloning is rampant. That "genuine Cisco" module might be a re-labeled Chinese blank programmed to report Cisco firmware.

Legacy equipment with discontinued transceiver specs. Lab environments where downtime is inconsequential. Personal home network experiments.

A network engineer at a startup: "We bought pulled transceivers for our office WiFi backhaul. Saved $600. One failed after 8 months. Bought a replacement for $40. Still ahead $560. Would I do it for customer-facing infrastructure? Never."

single mode fiber optic transceiver

Before clicking "buy" anywhere, decode these critical specs-where most buyers stumble into expensive mistakes.

Single-mode transceivers come in distance variants:

SR (Short Reach): 2-10 km, 1310nm wavelength, ~$15-$40

LR (Long Reach): 10-40 km, 1310nm wavelength, ~$60-$120

ER (Extended Reach): 40-80 km, 1550nm wavelength, ~$200-$400

ZR (Ultra-Reach): 80-120 km, 1550nm wavelength, ~$400-$800+

Here's the trap: buying a 10km transceiver for an 8km link seems smart. But fiber loss from patch panels, connectors, and cable bends means your "8km" link actually needs 10km optical budget. Always add 20-30% margin.

Common single-mode variants:

1G (SFP): 1.25 Gbps, backward compatible with Fast Ethernet switches

10G (SFP+): 10.3125 Gbps, requires 10G-capable switch ports

25G (SFP28): 25.78125 Gbps, increasingly common in modern data centers

40G (QSFP+): 4×10G lanes, single-mode variants less common

100G (QSFP28): 4×25G lanes, single-mode for data center interconnects

Mismatches kill links silently. An SFP+ transceiver in an SFP port physically fits but won't establish link. A 1G transceiver in a 10G port works-but only at 1G speeds.

Single-mode fiber has 9-micron core diameter. Wavelengths matter:

1310nm: Standard for 10-40 km reaches, better chromatic dispersion tolerance

1550nm: Preferred for 40+ km, lower attenuation but requires dispersion compensation

CWDM (Coarse WDM): 1270-1610nm range, allows multiple wavelengths on one fiber

DWDM (Dense WDM): ITU grid spacing, high-capacity metro/long-haul

Buying 850nm transceivers (multimode wavelength) for single-mode fiber creates 15-20 dB optical loss-your link will fail or flap constantly.

Digital Diagnostic Monitoring (DDM) or Digital Optical Monitoring (DOM) exposes real-time transceiver health:

TX power (transmission optical output)

RX power (received optical power)

Temperature

Laser bias current

Supply voltage

Without DDM, diagnosing "link down" becomes educated guessing. With DDM, you instantly see if TX power dropped (dying laser), RX power is too low (fiber issue), or temperature is spiking (cooling failure).

Transceivers without DDM cost $5-10 less. That savings evaporates the first time you spend 2 hours troubleshooting what DDM would reveal in 30 seconds.

Here's what vendors don't advertise: "compatible" exists on a spectrum.

Transceiver installs, switch detects it, link establishes, DDM functions, zero warnings. Maybe 30% of third-party modules achieve this with first-try compatibility.

Module works but switch logs "unsupported transceiver detected" warnings. Link is stable, performance is fine, but your monitoring system floods with alerts. Some IT departments have policies against anything triggering warnings-even cosmetic ones.

Switch needs a command to accept third-party modules:

Cisco: service unsupported-transceiver

Juniper: set chassis fpc X pic Y port Z optics-options allow-any

HP/Aruba: allow-unsupported-transceiver

Not technically hard, but requires console access-problematic for remote installations.

Switch firmware actively rejects module. Some OEMs pushed updates specifically to block third-party transceivers (looking at you, legacy Brocade). Your options:

Rollback firmware (not happening in production)

Find older module with different encoding

Pay OEM tax

Ask for specific model testing: "Does this work with Cisco Catalyst 9300 running IOS XE 16.12.4?" Generic "works with Cisco" means nothing.

Request DDM screenshot: If vendor claims DDM support, make them prove it with actual switch output showing transceiver diagnostics.

Check community forums: Search "[your switch model] third-party transceiver" on Reddit, ServersTheHome, or NetworkEngineering subreddit. Real-world experience beats marketing claims.

Start with one: Buy a single module, test for 48 hours under load. Watch for CRC errors, link flaps, or environmental warnings. One $60 test module beats 50 failed $60 modules.

Two decades of sourcing optical components taught me these warning signs:

If a transceiver is 80%+ cheaper than market average, it's either counterfeit, defective, or stolen. Legitimate transceivers have floor prices based on component costs. A 10GBASE-LR single-mode transceiver cannot be profitably manufactured and sold for $15-the TOSA (Transmitter Optical Sub-Assembly) alone costs $12 wholesale.

Vendors hiding TX/RX power budgets, wavelength accuracy, or extinction ratios are hiding problems. Legitimate modules publish full specs matching MSA standards. If you see "contact us for specifications," that's a red flag unless it's truly custom engineering.

Where was this module manufactured? Who did QC testing? What certifications does it hold? Vendors should answer this instantly. Hemming and hawing suggests gray-market sourcing.

"Email support@genericvendor.com" is useless at 3 AM when your link is down. Look for:

Direct phone numbers (and call them before buying)

Named technical contacts

Published support hours

RMA process clearly documented

"Great product, works perfectly!" with zero technical detail appears across counterfeit listings. Real reviews mention specific switches, firmware versions, distance tested, and problems encountered (then solved).

Purchase price is 40-60% of true transceiver cost. Here's what enterprises actually track:

Module purchase price

Shipping/expediting fees

Import duties (if international)

Purchase order processing overhead

Technician time for installation

Testing and validation

Documentation updates

Potential configuration changes

Spare inventory holding cost

Power consumption (varies 1-4W per module)

Monitoring system overhead

Cooling requirements

MTBF (Mean Time Between Failure): OEM modules ~20 years, quality third-party ~15 years, questionable sources ~3-5 years

RMA logistics and downtime

Emergency replacement premium

Reputation/SLA impacts

Component	OEM Path	Third-Party Path	Gray Market Path
Purchase (@100 units)	$48,000	$12,000	$6,000
Annual failure rate	0.5% (0.5 units)	2% (2 units)	8% (8 units)
Replacement cost/incident	$200	$200	$200
5-year failure cost	$500	$2,000	$8,000
Support time savings	10 hrs/yr	0 hrs	-20 hrs/yr (@$100/hr)
5-year support impact	$5,000	$0	-$10,000
5-Year TCO	$53,500	$14,000	$4,000

The math depends heavily on your downtime cost. A 30-minute outage costs a hedge fund $500,000? OEM transceivers are a bargain. Running a home lab? Gray market risk is manageable.

Smart network architects don't use one channel-they use the right channel for each situation.

Tier 1 - Mission Critical: Core routers, primary data center interconnects, customer-facing infrastructure. OEM or premium third-party (FS.com, FluxLight) with lifetime warranties. Compatibility is non-negotiable.

Tier 2 - Important But Redundant: Dual-homed links, backup paths, aggregation layers with failover. Quality third-party modules. If one fails, automatic failover covers while replacement ships.

Tier 3 - Non-Critical: Office networks, lab equipment, dev/test environments. Amazon, gray market, or pulled modules acceptable. Downtime costs are measured in minor annoyance, not revenue loss.

For 50+ units, negotiate directly with manufacturers. A Fortune 500 company buying 500 transceivers can phone Hisense Broadband and get quotes 40% below their listed prices. That same company buying 2 transceivers should just click "add to cart" on FS.com.

One enterprise strategy: Buy 70% of forecasted volume from cost-effective third-party suppliers. Keep 30% rapid-response capacity via distributor relationships for emergency replacements. You optimize cost on planned deployments while maintaining fast response for failures.

Quality varies wildly-but the top tier (FS.com, FluxLight, 10Gtek) use the same component suppliers as OEMs and publish failure rates around 0.02-0.05% annually versus OEM's 0.01%. Most failures happen during first 48 hours (infant mortality). If a third-party module survives the first week, it typically runs for years.

Yes, with caveats. They need identical specifications (wavelength, distance rating, data rate). Don't mix 1310nm and 1550nm modules on the same fiber-even if both ends work individually, chromatic dispersion can cause intermittent errors. Mix at will when they're parallel links (different fiber pairs).

Check three places: (1) Vendor's public compatibility matrix (many OEMs publish this quietly), (2) Community forums like Reddit's r/networking, (3) Just try it-most modern switches have CLI commands to allow third-party modules. Worst case? You return it within the window and eat return shipping.

Component-wise? Often nothing-both use Finisar or Lumentum internals. The Cisco premium buys: guaranteed TAC support, zero firmware compatibility issues, supply chain traceability for regulated industries, and SLA coverage. If you don't need those, you're paying for branding.

Absolutely. Outdoor requires extended temperature range (-40°C to +75°C minimum), UV-resistant housings, and often conformal coating for moisture resistance. Regular commercial transceivers (0°C to +70°C) will fail within months in outdoor enclosures where summer temps hit 130°F+. Budget $80-$200 extra for ruggedized variants.

Technically possible with mode-conditioning cable patches-but never recommended. Using multimode transceivers (850nm) with single-mode fiber causes 15-20 dB loss and links flap unpredictably. Going reverse (single-mode transceiver on multimode fiber) works better but requires precise alignment and still risks damage from back-reflections. Just match fiber type to transceiver type.

MTBF (Mean Time Between Failure) ranges from 500,000 hours (57 years) in datasheets to 5-10 years actual operational life. Lasers degrade over time-expect 0.5-1 dB TX power loss over 5 years. Environmental stress accelerates aging. Budget 7-10 year replacement cycles for production environments, 3-5 years for harsh conditions.

Bookmark this decision tree-it'll save you hours of aimless shopping:

1. Define Your Non-Negotiables

Required transmission distance (add 30% margin)

Switch/router compatibility with specific firmware version

DDM/DOM support for diagnostics

Budget constraints (TCO, not just purchase price)

Lead time requirements

2. Map to Sourcing Channel

Mission-critical + unlimited budget → OEM direct

Enterprise deployment + cost consciousness → FS.com, FluxLight, specialized distributors

Industrial/harsh environment → Lanshack, Moxa, Phoenix Contact

Lab/non-critical + price sensitivity → Amazon with verification, or gray market

3. Validate Before Volume Purchase

Order 1-2 test modules

Verify physical installation and link establishment

Check DDM functionality in your monitoring system

Run 48-hour burn-in with traffic generation

Document compatibility for future orders

4. Build Vendor Relationships Even if you're buying cheap, know your fallback. When that single-mode link goes down on a Saturday, which vendor answers the phone? Which one has spare inventory they'll overnight? That relationship is worth 20% price premium when you need it.

5. Document Everything Track serial numbers, purchase dates, installation locations, and failure patterns. After 50+ transceiver purchases, you'll see trends-maybe one vendor's 10km modules consistently fail at 3 years, while another's run 7+. That data is gold for future procurement.

The single-mode fiber optic transceiver market in 2025 offers unprecedented choice-and unprecedented complexity. The gap between the cheapest and most expensive sourcing options spans 1000%+. But here's what two decades in the field taught me: the best source isn't the cheapest or the most expensive-it's the one that matches your actual risk tolerance and operational requirements.

A $12 transceiver from FS.com that arrives in 48 hours with verified compatibility beats a $569 Cisco module on 6-week backorder. But that same $12 module is wrong for a hospital's patient monitoring network where failure means liability.

Know your scenario. Match it to the right channel. Test before you commit. And keep a spare.

Whether you're sourcing a single mode fiber optic transceiver for a data center expansion or replacing legacy equipment, the strategies in this guide will help you avoid the costly mistakes that plague 60% of first-time buyers. The right supplier, matched to your specific deployment requirements, makes all the difference between a smooth installation and a weekend debugging session.

That's the unsexy truth about sourcing single mode fiber optic transceiver modules that nobody puts in marketing materials.
