OPTICAL FIBER RECEIVER

 INTRODUCTION

YGS9750L/E/K field optical receiver is adapted to the optical passive access network fiber to the last light node and design the low light power light receiving products. This unit is made of high sensitivity, low noise phototubes pre-filter gaas amplification chip, the last stage adopts gaas power amplifier module, the maximum multiplier output level can reach  1 x 110dBuV (push-pull module 1 x104dBuV); This machine has configuration high-precision lightning surge protection AGC optical switching power supply, automatic output level control, light receiving power LED digital display, because basically equipment superior performance, plus carefully designed circuit to cooperate, thus ensures the performance index is high, good reliability. Meanwhile, in order to solve operators, equipment management and machine adds selection webmasters, through the etheric transponder telemetry network can realize HFC network management system monitoring function. Model suffix "E" for EOC insert function.

FEATURES

● High quality: the light AGC control, 3dBm receiving, CNR ≥ 51dB superior GB;
● Reliability: antistatic amplification tube, preventing lightning switch power, low consumption and energy saving;
● Intuitive: the high-pressure ball lamp working properly instructions, light receiving power LED digital display;
● Net tube type: can selection, the entire network transponder telemetry network monitoring, SMS alarm.
