Summary

The YGS86/10050R outdoor four-output optical receiver is a low optical power optical receiving device designed to adapt to the NPON network architecture EPON+EOC. It adopts optoelectronic integrated module or high sensitivity photocell, low noise front GaAs amplification chip, and the last stage adopts UK OEI gallium arsenide power double amplification module, the maximum output level can reach 4×104/4×108dBuV(YGS10040R); This machine is also equipped with high-precision lightning protection switching power supply, light control AGC automatic output level control, light receiving power LED digital display, EOC inserter(data channel 5~65MHz). Due to the superior performance of the main equipment and the well-designed circuit, the performance index is high and the reliability is good. At the same time, in order to solve the operator equipment management and two-way network transformation, the machine has added an optional network management transponder with EOC duplexer, which can realize HFC network management system monitoring and EOC insertion function through Ethernet network.
