Summary
The dual-module FTTH terminal is a combination of an optical network unit (ONU module) and a CATV optical receiver (module). This machine adopts high-performance GPON ONU chip and low-power optical receiving technology solution, and has a dual-module structure, which can meet the gradual requirements of fiber-to-the-home services. The modular GPON ONU module unit has four 10/100Mbps Ethernet ports; the modular ultra-low optical power reception (-15 to -5 dBm) has one RF 76dBuv constant output, and the main unit can be down-regulated by -4 dB and up-regulated by +6 dB. The unit also has an ONU module working status indication, a CATV light receiving signal indication and an RF output level indication on the panel; when the EPON ONU module is inserted, the network management information of the optical receiver is synthesized on the ONU, and the ONU is unified with the network management, and supports WEB, OAM, TR069 and SNMP.
Features
