Finisar FTLF8519P3BTLHW1 850nm multimode SFP fibre optic transceiver.
The Finisar FTLF8519P3BTLHW1 is a small form-factor pluggable (SFP) fibre optic transceiver module operating at 850nm wavelength for multimode fibre applications. This module supports Gigabit Ethernet and Fibre Channel connectivity, providing reliable high-speed data transmission across enterprise and data centre networks.
This transceiver is designed for short-reach applications where multimode fibre infrastructure is deployed, typically within buildings or campus environments. It plugs into standard SFP ports on switches, routers, and network interface cards to enable optical connectivity.
Finisar was a leading manufacturer of optical communication products before its acquisition by II-VI Incorporated. The FTLF8519P3BTLHW1 remains widely deployed in existing network infrastructure and continues to be sought after for maintenance and expansion of legacy optical networks.
