Optical repeater TDZ-R

communication system

Ticom TDZ-R type GSM-R digital optical fiber repeater is a kind of railway GSM-R communication base station signal pulling remote equipment. With the digital software radio technology, the digital optical fiber near end machine converts radio frequency signal to digital signal, and then the signal is transmitted from the digital optical transceiver to the digital optical fiber remote machine. The digital signal is converted to a radio frequency signal by the remote machine, and then it is sent to the overlay area by the antenna feeder system. The GSM-R digital optical fiber repeater developed by Ticom Tech fully complies with the TB/T3367-2016 "the technical requirements of GSM-R digital optical fiber repeater " and TJDW185-2016 "the technical requirements of digital optical fiber repeater system for railway digital mobile communication system (GSM-R) ", and has obtained the certificate issued by CRCC. It is also the first product which passed the test on the C3 high - speed rail line in China. Main features: 1. It has the time delay adjustment function, which solves the multipath interference of the repeater caused by the optical fiber delay. 2. It has the uplink noise suppression function, which can eliminate the noise accumulation caused by the optical fiber repeater and the lifting bottom noise of the base station. 3. The close - end machine and the remote machine have a variety of networking methods to meet the needs of various types of engineering, thus providing an advanced solution for the railway.
