GENERIC 25Gbps 850nm SFP28 Optical Transceiver

The SFP28-MM-25G-85-100M is a single-Channel, Pluggable, Fiber-Optic SFP28 for 25 Gigabit Ethernet and Infiniband EDR Applications. It is a high performance module for short-range data communication and interconnect applications which operate at 25.78125 Gbps 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 Fibertronics proven circuit and VCSEL technology to provide reliable long life, high performance, and consistent service.

This high-quality GENERIC Compatible 25Gbps 850nm SFP28 Optical Transceiver. A cost-effective solution that provides high bandwidth and transmission rates over short distances. Each transceiver is 100% optically inspected and tested for compatability before shipping.
