Cable TV 2*9dBm Fibre Optical 1550nm External Modulation Optic Transmitter

 

Product Features:

■ High quality: original system optimization control technology, RF pre-distortion technology in the case of ensuring excellent performance of CNR system to obtain the largest CTB, CSO and SBS indicators.

■ Flexibility: the phase modulation technology of the external modulator maximizes the incoming optical power to obtain long distance transmission while guaranteeing the excellent performance of the system CSO, and the SBS threshold 13, 16, 19 is field adjustable and applicable to different network transmission.

■ Reliability: high reliability design, built-in high performance double switch power supply, hot backup work, MS automatic switching; Automatic temperature control of chassis heat dissipation.

■ Intuitive: the machine is equipped with a microprocessor to monitor the working state of the external modulator and laser, and the key working parameters of the equipment can be visually displayed through the front panel display window.

■ Network management: built-in network management transponder, meet national standards, compatible with SCTE HMS standard.
