Description
The F-tone Networks FTCS-8528G-02DI is a single-Channel, Pluggable, Fiber-Optic SFP28 for 28.05Gbps Fiber Channel/OTU4 SFP28 SR Applications. It is a high performance module for short-range data communication and interconnect applications which operate at 28.05Gbps(32GFC) up to 70 m using OM3 fiber and 100m using without KR-FEC,and 300m using with FEC. This module is designed to operate over multimode fiber systems using a nominal wavelength of 850nm. The electrical interface uses a 20contact edge type connector. The optical interface uses duplex LC receptacle. This module incorporates F-tone Networks proven circuit and VCSEL technology to provide reliable long life, high performance, and consistent service.
