FS QSFP-ER4L-100G, 100GBASE-ER4L QSFP28 1310nm 40km Transceiver Module

Looking for a fast, reliable link that can stretch over dozens of kilometres? The FS QSFP-ER4L-100G, 100GBASE-ER4L QSFP28 1310nm 40km Transceiver Module gives you exactly that. It is a QSFP28 transceiver designed for 100 Gbps Ethernet and works on single-mode fiber up to 40 km. If your network is losing speed or cannot reach a remote site, this module solves the distance problem while keeping the signal clean and stable.

Many data centres and campus networks need to connect buildings that are far apart. The lack of a long-reach solution forces you to add extra equipment, which raises cost and complexity. This problem matters because every extra hop adds latency and a point of failure. The FS QSFP-ER4L-100G provides a single-module answer: 100 Gbps over 40 km of SMF, low power use, and built-in diagnostics, so you can extend your network without extra repeaters.
