25Gb/s SFP28 Transceiver SFP28-28G-SR dual fiber multimode 100m 850nm LC DDM


The Nufiber SFP-25G-SR is a single-channel, pluggable, fiber-optic SFP28 transceiver module for 25G Ethernet applications. It is a high performance module for short-range data communication and interconnect applications which operate at 25.78125Gb/s up to 70m using OM3 fiber or 100m using OM4 fiber. This module is designed to operate over multimode fiber systems using a nominal wavelength of 850nm. The electrical interface uses a 20 contact edge type connector. The optical interface uses duplex LC receptacle. This module incorporates Gigalight Technologies proven circuit and VCSEL technology to provide reliable long life, high performance, and consistent service.
