TenFourOptics (TFO) supplies OEM-compatible transceivers from 800G to 1G — plus DACs and AOCs — validated in real network environments before they ship. No distribution layer. In-stock parts ship same or next business day. One job: your link comes up green — quick, first time, and it stays that way.

How we do it: Every TFO part is built to the MSA and IEEE standards its part number claims, then coded to the host EEPROM so it comes up as a native module — full diagnostic visibility, no compatibility warnings, no configuration required. We publish documented compatibility per part, drawn from each OEM's published matrices and our own lab verification. If your exact line card or OS release isn't listed, email 10.4@tenfouroptics.com and we'll confirm fit before you buy. See Tested & Proven for the full process.

Every optic is backed by the GreenLights4Life® Limited Lifetime Replacement Warranty. A failed transceiver in a live network isn't a part cost — it's a truck roll, a maintenance window, an SLA breach. That's why every module passes traffic conformity, DOM threshold, and EEPROM/MSA verification before it ships. It's why we don't ship test reports: an optic either works perfectly, or it doesn't leave our dock.

The market we built for is now arriving. Optical transceivers are a $15B+ market growing double digits, and the AI-data-center slice — 400G, 800G, and beyond — is growing better than 50% a year as operators move off vendor lock-in. A decade of proven field performance put TFO in position before the wave. We're built to scale straight into it.
