Finisar FTLX8574D3BCL SFP Optical Transceiver
The Finisar FTLX8574D3BCL is a 10G SFP+ multimode optical transceiver built for short-reach 10GBASE-SR Ethernet and 10G Fibre Channel links, making it a standard choice for data center and enterprise switch-to-server interconnects over OM3/OM4 cabling. It suits IT resellers and system integrators provisioning SFP+ ports on mainstream switching platforms. As with any transceiver, confirm your switch vendor’s coding and compatibility policy before deployment.

Good to know
- Requires multimode cabling with duplex LC patch cords; pair with an SR-capable SFP+ port on the opposite end — commonly deployed across top-of-rack switch families supporting 10GBASE-SR.
- Within the SFP+ family, this is the short-reach SR variant; for longer runs over single-mode fiber, an LR-type transceiver would be the appropriate counterpart.
- Buying tip: match reach to your installed fiber grade — OM4 supports up to 400 m while OM1 is limited to 26 m — and verify DOM/DDM visibility is enabled in your switch software for link monitoring.
