This Huawei eSFP transceiver operates at 1310nm on single mode fiber, supporting Gigabit Ethernet links up to 10km. It is a common choice for connecting buildings or floors over fiber where the distance is too far for copper cabling but does not need the reach of long haul optics. Antofity Concepts supplies this transceiver for Gigabit fiber links across Kenya, and can confirm compatibility with your existing switch platform before you order.
