Chassis CATV Optical Receiver With Double Receive Two Output 2×102
CATV Optical Receiver Summary
GSS-2 is used in optical fiber-to-home CATV1550nm optical signal reception, 2-channel master, standby optical signal input, RF automatic switching, corresponding to 2 RF signal monitoring and 2 high performance RF outputs. This machine adopts high performance photoelectric conversion, optical control AGC, full gallium arsenide amplification, whole machine MCU control, RF output balance and level adjustable, main and standby power module; built-in network management transponder, supports WEB,SNMP,APP, network management monitoring content: 2 optical input power and RF level, RF output level, local on-line temperature, working voltage and current, remote selection of optical receiving channel, modulation The whole RF output equilibrium range and level size. Due to the high degree of selection of the main equipment and the carefully designed circuit cooperation, it ensures that the performance index is high, the reliability is good, and the average fault-free time (MTBF) is more than 50000 hours. It is an ideal radio and television transmission network ring network (sub-front-end), double line and township wide power station receiving equipment.
