AGC Optical node

. Summary 1) BEST-OR036 series field 2-way output optical receiver is used for long-distance optical fiber transmission of TV image signal, digital TV signal telephone sound signal and data (or compressed data) signal. 2) Our company have been developing CATV optical receiver since 1993, we have studied the various technical performance of CATV optical receiver for more than 17 years, which has accumulated a lot of experience in product development and engineering practice, improve the internal circuit, external structure and performance index. 3) At present, our company has acquired the most advanced CATV optical receiver design skills and production technology in domestic industry; at the same time, the yield of our CATV optical receiver is first in this area. . Performance Characteristic 4) Forward optical receive part adopts PHILIPS, PHOTON and E-O PIN Optical Receiving IC, import PHILIPS or MOTOROLA low-noisy push-pull amplify module in pre-RF amplify circuit, import PHILIPS or MOTOROLA power double amplify module ( or depends on customers, adopt GaAs). 5) Return optical receive part adopts high-performance FP or DFB laser as optical source, adopts PHILIPS or MOTOROLA low-noise amplifier module as RF amplifier, ensure NPR. 6) Insert Dual-Filter, insert Fix-Equalizer, Fix-Attenuator insert output splitter, eighth-order optical power indication, reasonable testing connector, make more convenient 7) Aluminum waterproof housing, high-capability power switch, anti-thunder system, make sure work properly outdoor. .
