Description
The F-tone Networks FTCS-8525G-02D is a single-Channel, Pluggable, Fiber-Optic SFP28 for 25.78125 Gigabit Ethernet SFP28 SR Applications. It is a high performance module for short-range data communication and interconnect applications which operate at 25.78125 Gbps up to 70 m using OM3 fiber 100 m using OM4 fiber without FEC or 300m OM4 with KR-FEC. 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 F-tone Networks proven circuit and VCSEL technology to provide reliable long life, high performance, and consistent service.
