1. Summary
SNP8602RJ optical receiver is a advanced product designed for CATV HFC network. Aluminum alloy shell, built-in microcomputer automatic control unit and national standard II class network transponder are adopted. Its structure is compact. And it’s convenient to install and debug. It’s the best choice for CATV HFC network.
2. Performance Characteristic
Advanced optical AGC control circuit is adopted to ensure output level and link index(C/CTB and C/CSO)be constant within the receiving optical power range from -8 dBm to +2 dBm.
Stepping electric control of output level and output seleme is completed by built-in microcomputer automatic control unit with programmable RF power control chip. The running parameters of received optical power, RF attenuation, RF equilibrium quantity and direct current working volts will be displayed by added digital display circuit.
The PIN optical detector with high-sensitivity is adopted. GaAs MMIC amplifier is used at preceding stage. And imported GaAs RF amplifier module at output stage to ensure excellent performance index.
Network monitoring will be achieved by the built-in national standard class II responder through Ethernet.
There are special aluminum alloy shell, switching power supply with high reliability and strict anti-lightning system to ensure steady operation.
