Black Box Corporation LFP413 SFP Transceiver Module

The Black Box LFP413 SFP transceiver delivers 1.25 Gbps over single-mode fiber, using a 1310 nm laser and a 10 km reach, with extended diagnostics built into the module for on‑board monitoring and fault signaling. This LC duplex SFP plugs into standard SFP ports in switches, routers, and other network gear and is rated for operation from -40°C to +85°C, enabling deployment in data centers, campus networks, and environments with wide temperature variation. Verified by Black Box datasheets and official product listings, the LFP413 is consistently described as 1250 Mbps (1.25 Gbps) with a 1310 nm wavelength over SMF, LC connector, and a 10 km reach, while the extended diagnostic capability is repeatedly noted. As part of Black Box's SFP family, the LFP413 is documented to work with Black Box extenders and to be compatible with generic SFP modules in appropriate systems, offering a flexible option for scalable fiber networks.
