Black Box LFP403 SFP Optical Transceiver Module

Black Box LFP403 SFP optical transceiver module is a compact SFP transceiver that enables a standard SFP port to interface with 1310 nm single-mode fiber for long-reach links. It is rated for up to 155 Mbps and uses a 1310 nm transmitter with a 1310 nm receiver over single‑mode fiber, with a reach of up to 30 km, and a single LC simplex connector. The module includes extended diagnostics to monitor link status remotely, helping maintain fiber links in enterprise networks. Housed in a standard SFP form factor, this LC simplex transceiver is designed for optical-network equipment and is suitable for connecting switches, routers, or media converters over fiber, enabling scalable, fixed‑fiber links across campus or data centers.
