Product Details

25G SFP28 SR 850NM 100M TRANSCEIVER Compatible With Cisco Arista Juniper Dell Brocade

Description

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.
