1550 External Transmitter

1550 External Transmitter

1550nm External Transmitter is mainly used for long distance optical feeder transmission of television image signal. Digital TV signal and data signal. Double Microwave Sources SBS controlling technology researched and developed by us independently and advanced RF Pre-distortion circuit are adopted. Microcomputer automatic control system is built in it to make sure the excellent performance
