Finisar FTLF1436P3BCL Optical Transceiver
The Finisar FTLF1436P3BCL is a 25G SFP28 short-reach (25GBASE-SR) multimode optical transceiver intended for data center top-of-rack and server-side links over OM3/OM4 fiber. It suits system integrators and B2B hardware resellers building 25G Ethernet access layers, where fiber runs are short and power/thermal budgets are tight. As with all SFP28 modules, confirm that your switch and host platform support Finisar/I brand coding before deployment.

Good to know
- Compatibility: 25GBASE-SR SFP28 modules typically pair with 25G switch ports from vendors such as Cisco, Juniper, Arista, and Mellanox/NVIDIA families; vendor brand coding may restrict use to certified platforms, so verify firmware/module support lists first.
- Family positioning: within the Finisar SFP28 portfolio, this is the SR (short-reach) multimode variant — the economical choice for in-rack and adjacent-rack links, while longer runs would require single-mode LR-class modules.
- Buying tip: since reach is limited to 70 m on OM3 and 100 m on OM4, audit your existing fiber plant (patch panels, OM grade) before ordering, and match LC duplex OM4 patch cords to the link budget.
