indoor forward optical receiver

forward optical receiver used in transmitting optical of TV video,digital,voice data signal far away,quality index has improved

indoor forward optical receiver(catv receiver,optical node) TPRI-7504/TRIP-8604

Summary

Be developed through several years advanced experiences of CATV HFC network transmission equipment. Mainly used in transmitting optical fiber of TV video, digital, voice data signal far away. With 19 1U standard casing, combustion and drawbench in forward panel. The quality index has improved, set with high-reliability power switch; it is the first choice of big and medium size CATV HFC network.

Characteristic

1) Adopt PHILIPS, PHOTON or E-O high-sensitivity PIN detector and import PHILIPS or MOTOROLA low-noisy push-pull amplifier module. Adopt import PHILIPS or MOTOROLA double power amplifier module in output department.

2) Plug-in insert Dual-Filter and return reverse optical transmit parts, develop the return reverse access conveniently.

3) 19 1U standard machinery, forward panel sixth-order optical power indication, modulating output level and lean beam at forward panel.
