Máy Thu Quang Đường Tới FWR-8235A

FWR-8235A is our latest high-end CATV network optical receiver with two outputs, and reserves the second-channel optical input, it can be used as ring two channels automatic or manual switching, the former class adopt all-GaAs MMIC amplification, after grade is NEC GaAs power double module, optimizing the circuit design, coupled with our company's 10 years of professional experience in the design, so the machine achieves a higher performance index.

Single CPU controls LCD display and automaticly switchs some basic parameters. engineering debugging is convenient. It is the mainstream models to form CATV networks.

At the same time using the latest technology, our company has produced a network management transponders according to national standard, reserve network management transponder interface, and then can achieve HFC network management system monitoring functions through a network connection.
