FB-LINK 10G SFP+ SR Multimode Transceiver Module
An IEEE 802.3ae 10GBASE-SR transceiver built for 850nm multimode links up to 400m,manufactured and OEM-supplied by FB-LINK.
- Product Introduction
A Multimode 10G SFP+ SR Transceiver Built for 850nm Short-Range Links
The 10G SFP+ SR transceiver carries a full 10 Gb/s across ordinary OM3 and OM4 fiber, using an 850nm VCSEL and a PIN photodetector to keep the optics simple and the cost down. It is made for one job and does it well: high-bandwidth links inside the building - top-of-rack to aggregation, switch to server, floor to floor - where the run stays under 400 meters and single-mode optics would be an expensive overreach.
FB-LINK builds this 850nm module for exactly that short-range envelope, which is why it leaves out the DFB and EML lasers that long-haul optics carry. For anyone wiring a data-center row or a campus backbone, that means a lighter per-port cost without bending the IEEE 802.3ae signal quality your switches were designed around. The module is hot-swappable and reports its own health from the second it powers up, so it slots into a live chassis without booking a maintenance window.

Why Network Buyers Choose the FB-LINK 10G SFP+ SR Transceiver
Three arguments carry this short-range optic through both the engineering review and the cost review, usually in the same meeting.
The cheapest way to light a short 10G link
An 850nm laser over multimode fiber drops the expensive single-mode plant that LR and ER modules need. When every link in a row runs under 300 m, standardizing on the SR transceiver trims the optics line on high-density builds - and that saving stacks up fast across a full rack.
Interoperability that keeps your options open
FB-LINK builds every SFP-10G-SR to the IEEE 802.3ae 10GBASE-SR and SFF-8431 standards, so the module links against any compliant 10G SFP+ port. Your switch, NIC and patch-panel choices stay yours instead of getting locked to a single silicon vendor.
You see a link fail before your users do
On-board digital diagnostics stream temperature, supply voltage, laser bias and both TX and RX power in real time. Your NOC watches a link soften long before it drops - the difference between a planned swap and a 2 a.m. outage on a production path.
The 850nm Optical Design and DDM Diagnostics Behind the SR Transceiver
The optical path is matched to multimode fiber from the start, not adapted to it after the fact.
An 850nm VCSEL paired with a PIN receiver
The vertical-cavity laser couples cleanly into the 50µm core of OM3 and OM4 fiber, while the PIN photodetector holds receiver sensitivity below -11.1 dBm. With launch power sitting between -6.0 and -1.0 dBm, you get a defined link budget to subtract connector and fiber loss from during design - margin you can calculate, not guess at.
Reach that grows with your fiber
The same part number goes farther on better glass, so you stock one SKU and let the cable plant decide the distance:
| OM1 | OM2 | OM3 | OM4 |
|---|---|---|---|
| 33 m | 82 m | 300 m | 400 m |
Where the 10G SFP+ SR Transceiver Fits in Data Center and Campus Networks
Its 300 to 400 meter multimode reach lines up almost exactly with in-building and intra-campus distances, which is why FB-LINK sees this optic land in the same four places again and again.
Data center interconnect - top-of-rack switch to the aggregation or spine layer across a row.
Enterprise backbone - floor-to-floor and building-to-building links on one campus.
Storage Area Networks - low-latency, high-bandwidth paths for backup and replication.
High-frequency trading - short, deterministic server-to-gateway links where latency is the product.
All four sit comfortably inside the module's 0°C to 70°C commercial range - the same climate a controlled indoor rack already maintains. Spec OM3 for the standard 300 m envelope, or step up to OM4 when a run pushes toward 400 m.
Custom and OEM 10G SFP+ SR Manufacturing for Project Buyers
This is written for a sourcing manager, not a shopper, so here is what actually flexes on the FB-LINK line.
Coded to your switch platform
Modules are firmware-coded to whatever switch platform you name, so they read as fully supported optics in your NOS instead of throwing an unsupported-transceiver warning.
Your brand, or none at all
Ship the SR module under your own label, a neutral one, or unbranded in trays for integrators. Laser marking and retail packaging follow your artwork.
Built to your volume
Production is scheduled to the size of your project rather than a fixed shelf SKU, so a 50-unit rack build and a multi-thousand-unit rollout each get a plan sized to the order.
How Every 10G SFP+ SR Transceiver Is Tested for Compliance and Interoperability
Before an SR module leaves the floor, FB-LINK checks it against the standards that actually govern the link.
- Optical conformance to IEEE 802.3ae 10GBASE-SR, with wavelength, launch power and receiver sensitivity all verified against the rated windows.
- Electrical conformance to the SFF-8431 SFP+ interface for clean host-side behavior.
- DDM calibration, so the temperature, voltage, bias and optical power the module reports match what is really happening.
- Interoperability against the MSA baseline, so the optic links with compliant third-party 10G SFP+ ports.
Because the module is engineered to published standards rather than a proprietary spec, the classic third-party-optics headache - a switch flatly refusing the transceiver - is designed out before it ships.
MOQ and Lead Times for the 10G SFP+ SR Transceiver
Minimum order, sample terms and lead time are quoted against your real order profile rather than a fixed retail floor. FB-LINK provides samples for engineering validation before you commit to volume, and every production slot is confirmed with the order - so you plan your rollout against a real ship date, not a rough estimate.

Common Questions About Sourcing the 10G SFP+ SR Transceiver
Q: Can I run this module over single-mode fiber?
A: No. It is an 850nm multimode optic designed for OM2, OM3 and OM4 fiber, so single-mode plant will not link. If you need single-mode reach, move to a 10G SFP+ LR or ER module instead.
Q: How far does the SR transceiver actually reach?
A: Reach follows the fiber grade: 33 m on OM1, 82 m on OM2, 300 m on OM3 and 400 m on OM4. Connector quality and patch-cord loss shift real-world results, so leave margin against the -6.0 to -1.0 dBm launch and <-11.1 dBm receive figures.
Q: Will these work in switches from other brands?
A: Yes. FB-LINK builds the SR transceiver to the IEEE 802.3ae and SFF-8431 MSA baseline, so it interoperates with compliant 10G SFP+ ports. For platforms that enforce a compatibility list, we code the module to your specified switch so it registers as supported.
Q: Do you support OEM coding and private labelling?
A: Yes. As a 10G SFP+ SR supplier with in-house coding and marking, FB-LINK ships modules coded to your target platform under your brand, a neutral label, or unbranded for integrators.
Q: How do I confirm a module is healthy after install?
A: Read the DDM output. A healthy 10GBASE-SR module shows steady temperature, launch power inside the -6.0 to -1.0 dBm window, and receive power above -11.1 dBm. Anything drifting outside those ranges flags a link or cleanliness issue before it turns into downtime.
Q: Are samples available before a volume order?
A: Yes. As a factory-direct 10G SFP+ SR manufacturer, FB-LINK sends samples for bench validation, so your team can confirm the coding and optical performance in your own gear before committing to a production run.
