Description
The F-tone Networks Technologies FTCS-50G-CS-Oxxx is a single-Channel Active Optical Cable for 26.5625GBd PAM4 Ethernet Applications. It is a high performance module for short-range data communication and interconnect applications which operate at 53.125Gbps up to 70 m using OM3 fiber or 100 m 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. This module incorporates F-tone Networks Technologies proven circuit and VCSEL technology to provide reliable long life, high performance, and consistent service.
