Finisar FTLF1436W5BTD-E7 Optical Transceiver
The Finisar FTLF1436W5BTD-E7 is a 25G SFP28 short-reach (25GBASE-SR) multimode optical transceiver intended for data center and enterprise switch uplinks and server connectivity over OM4 fiber. It suits integrators and IT resellers deploying 25G Ethernet leaf-spine or top-of-rack links in environmentally controlled commercial rooms. Note that it is a commercial-temperature part, so it should be matched to equipment racks with standard ambient cooling rather than outdoor or extended-temperature installations.
Key specifications (table)

| Power Consumption | ≤ 1 W |
| RoHS Compliance | Yes |
Good to know
- Verify host-side compatibility before ordering: although the SFP28 form factor is mechanically shared with 10G SFP+ ports, this module targets 25G-capable switch and NIC ports; confirm supported vendor lists for your switch platform.
- As a 25GBASE-SR module, it sits in the short-reach tier of the 25G family, covering intra-rack and adjacent-rack runs over OM4 up to 100 m, complementing longer-reach single-mode options in the same port class.
- Pair with matching multimode LC duplex patch cords and order transceivers for both ends of the link; budget within the 100 m OM4 reach figure when planning cable routes (guidance only — actual reach is installation dependent).
