Description

The GSDT-FTX-II-1550 forward transmitters are part of a new series in the Excelsior optical transmission platform that will mix with other GSDT-FTX series to integrate into the same GSDT-link Chassis. The module contains a high performance, advanced pre-distortion circuitry achieves superior CSO and CTB, and ideal for broadcast and narrowcast applications. It can provide a wide range of optical output power to deliver both analog and digital signals. All configuration parameters of modules can be monitored by LED screens on the front panel of the module, or by the GSDT-EMS equipment management module.
