Detailed Product Description

ONU-0421P ONU, in accordance with CTC requirement of EPON equipment, is designed mainly for FTTH use and FTTO/FTTB use as well. ONU Series products (CTC EPON V1.3) support 1000Base-PX10/PX20 standard with 1:32 maximum optical splitting ratio and 10/20km distance, and provide 1uplink GE PON port. ONU-0421P user interface includes: 4 10/100BASE-T data ports, 2 FXS ports, 1 CATV RF port, which provide data, voice and video service for the users. WEB is adopted for local network management for OUN-0421P ONU, and OAM for remote network management. OUN-0421P ONU also supports remote upgrade of software. OUN-0421P ONUs together with Softels OLT equipment could realize flexible network structure and maintenance and provide total FTTx solutions.
