Optical receiver + EoC + ONU + Class II network management responder
ONB4000 basic configuration is GZB series optical node with high performance and multi-function, can install EoC master (four in max), ONU, IP network responder (class II), and four-way low-loss data signal insert output ports (4 ways IP data in max, can support 256 terminal addresses simultaneously).
Features:
1. Receiving optical power be displayed by 8digits, easy for maintenance.
2. Could install ONU inside (or select fiber transceiver or switch and so on as data source), support flexible configuration structure.
3 Adopt excellent high-efficient switch power supply, possess perfect over-voltage and under-voltage protection function, thus to improve the reliability of the whole machine;
4. The combination of network management responder which complied with national standard and headend network management software can remotely manage ONB optical network base;
5. Optical node adopt aluminum casting inner type and modularization design;
6. Adopt high sensitivity optical receiving module and high-power GaAs module, output from four ports through four splitters, when receiving at -4dBm, output level can be more than 106dBuV/CH;
7. Each downstream signal output port has independent EOC signal inserter;
8. Four independent low-loss high-isolation EOC cavity inserter, with 90dB high port isolation to ensure that each MASTER path can work out the best performance;
9. EOC signal insertion does not influence any output performance of optical node;
10. Can install two independent power module inside, which can provide DC electric power supply for ONU and four masters, no need of independent external DC converter;
11. Easy for installation and save the space, full configuration (with four EoC masters, ONU, network management module) the consumption will be lower than 60W, especially suitable for the HFC network which will carry out the data service.
