25GBASE-SR SFP28 Optical Module 100M MMF For 25G Switches And Server Adapter

Top-trans TOP-SFP28-25G-SR is a single-channel, pluggable, SFP28 fibre-optic for 25 Gigabit Ethernet and Infiniband EDR Applications. It is a high-performance module for short-range data communication and interconnects applications which operate at 25.78 Gbps up to 70 m using OM3 fibre or 100 m using OM4 fibre. This module is designed to operate over multimode fibre systems using a nominal wavelength of 850nm. The electrical interface uses a 20 contact edge type connector. The optical interface uses a duplex LC receptacle. This module incorporates Topstar proven circuit and VCSEL technology to provide reliable long life, high performance, and consistent service.
