Product Description
GSM-R Digital Optical Fiber And Power Amplifier Dual Backup System
GSM-R digital optical fiber amplifier dual backup system is a kind of digital optical repeater with higher system stability and dual backup function of power supply and power amplifier. The system is composed of direct coupling main unit and remote unit, with duplex application. It transmits the signal of the cluster base station to the remote unit through the transmission of optical fiber. The signal of the cluster base station is amplified by the remote unit, and finally transmitted through the antenna feeder system, so as to expand the signal coverage of the base station.
