FB-LINK designs, codes, assembles and tests under one roof. That's what lets us fix a compatibility issue, tune a reach, or turn a custom run around without a middleman in the loop — and it's the difference a buyer feels the first time a module fails a switch's compatibility check.
Assembly runs in a 1,600㎡ class-1000 cleanroom in Shenzhen, and roughly half of our 300-plus staff sit in R&D, many holding master's or doctoral degrees. When something doesn't come up on your platform, you reach the people who coded the firmware — not a distributor's ticket queue.
Many switches lock-code their ports and reject anything they don't recognise. We code each module to the platform you name — Cisco, Arista, Juniper, NVIDIA/Mellanox — and every unit carries DDM/DOM, so you can read live optical power and temperature and confirm a link before it ships in volume.
Standardising your bill of materials on a single fiber optic module maker cuts qualification overhead as a fabric migrates from 100G to 400G and up to 800G/1.6T. Same coding, same test regime, same commercial contact across every speed you deploy.
Modules rarely deploy alone. FB-LINK also builds the transport and passive layers around them, so one purchase order can carry the optics plus the gear they plug into — one contact, one set of lead times.
The right module depends on the job. Here's how buyers usually map our range onto the three networks we ship into most.
100G QSFP28 and 400G QSFP-DD for spine-leaf, 800G OSFP and 1.6T OSFP224 for GPU fabrics, DAC/AOC for in-rack — all coded to the switch platform in your row.
LR4, ER4 and single-fiber 80 km modules for reach, plus CWDM/DWDM optics that ride our own DWDM and DCI/OTN platforms for capacity over a single fiber pair.
25G SFP28 and BiDi optics for fronthaul rings, with industrial −40 to 85°C grades for cabinets and outdoor sites that see real temperature swings.
Written for the sourcing managers and network engineers who need more than a catalogue part. These are the four questions we field most before a custom run — answered straight.
Name your target switch and we code each module to be recognised on that port. Owning the firmware is exactly why buyers move from a stock reseller to a manufacturer — a coding mismatch stops being a support ticket and starts being a build spec.
Modules can carry your label, part numbers and packaging for resale or internal asset tracking. Your design and coding details are handled as confidential to your account and never shared downstream.
Free samples let you check reach, DDM readings and platform compatibility on your own equipment before a bulk order. Sampling and quotation enquiries are answered within 24 hours.
Order quantity and lead time depend on speed tier, coding, and whether a SKU is stocked or custom — so we confirm both against your actual line items rather than quote a blanket number. Send the part list and volumes and we'll scope it directly.
Quality oversight runs across each production phase against international performance benchmarks. These certifications are held at company level and can be verified on request.

Q: What optical transceivers does FB-LINK manufacture?
A: FB-LINK manufactures optical transceivers from 1G to 1.6T — 1000BASE SFP, 2.5G SFP, 10G SFP+, 25G SFP28, 40G QSFP+, 100G QSFP28, 200G QSFP56, 400G QSFP-DD, 800G OSFP and 1.6T OSFP224 modules, plus DAC and AOC cables. SR, LR, ER, ZR, CWDM, DWDM and BiDi reaches are available across the tiers.
Q: Are FB-LINK optical transceivers compatible with Cisco, Arista and other switches?
A: Yes. Because many switch platforms lock-code their ports and reject unlisted optics, each module is coded to match the platform you specify — Cisco, Arista, Juniper, NVIDIA/Mellanox and others. Tell us the switch you're deploying against and we code and test to it before shipping.
Q: Can I get a free sample before placing a bulk order?
A: Yes. Free samples let you verify reach, DDM/DOM readings and compatibility on your own hardware before you commit to volume. Sampling and quotation enquiries are answered within 24 hours.
Q: Does FB-LINK offer OEM, ODM and private-label modules?
A: Yes. As a manufacturer that owns its design and coding, FB-LINK builds to client specifications, applies custom platform coding, and marks units with your brand, part numbers and packaging. Design details stay confidential to your account.
Q: What certifications do FB-LINK optical transceivers carry?
A: FB-LINK holds ISO 9001, ISO 14001, RoHS and CE. RoHS and CE matter for import and deployment in the EU and comparable markets, while ISO 9001 governs the quality process behind consistent performance. The company is also a recognised national high-tech enterprise with 65+ invention patents.
Q: Can FB-LINK supply the rest of the optical link too?
A: Yes. Alongside optical transceivers, FB-LINK builds DWDM and CWDM systems, DCI/OTN transport, FTTX equipment, fibre patch cords and optical switches — so the optics and the transport and fibre they connect to can sit on one purchase order with a single point of contact.
Send your target part list, speeds and switch platform. We'll confirm compatibility, stock and pricing — and reply within 24 hours.
