What this part does
The Finisar FTLF8536P4BCV is an SFP28 optical transceiver designed for 25GBase-SR and 10GBase-SR network links. It uses an LC duplex connector and supports eCPRI traffic for short-wavelength fibre runs in server and data-centre environments. The module is supplied new and ready for immediate deployment.
The spec that decides fit
This module provides a single LC duplex port operating at 25GBase-SR with backward compatibility to 10GBase-SR. It targets short-wavelength multimode fibre links and carries eCPRI signalling. No other interfaces or media types are included in this part.
Who should buy and who should not
Network engineers upgrading or repairing 25 GbE or 10 GbE SR links in compatible switches, routers or server NICs will find this transceiver a direct match. Buyers who need long-range single-mode optics, CWDM or DWDM wavelengths, or a different form factor such as QSFP28 should look elsewhere.

Questions about this item
What does the 25GBase-SR rating mean for real-world throughput?
The module is specified for 25GBase-SR operation, providing a 25 Gbps lane over multimode fibre for short-range server links.
What does the SFP28 interface cap at in practice?
The SFP28 form factor supports a single 25 Gbps lane; the module implements 25GBase-SR over an LC duplex connection.
What physical slot and cabling does the FTLF8536P4BCV need?
It plugs into any SFP28 port and connects with a standard LC duplex multimode fibre patch cord.
