- Product Description - 

   

        The 4-port EPON-OLT is an OLT device that follows the IEEE802.3ah and the People's Republic of China Communications Industry Standards (YD/T 1475-2006), fully supporting CTC2.0/2.1, auto discovery and being compatible with each vendor ONU.Build a highly efficient EPON solution.The 4-port EPON-OLT supports PON transmission rates of 1.25Gbps, efficient bandwidth utilization, and Ethernet business support capabilities to help operators provide reliable business quality assurance for their users.The optical ratio of 1:64 supports the hybrid network of different types of ONU, minimizing the investment of operators.The 4-port EPON-OLT uses industry-advanced technology, with powerful features and QoS assurance in the Ethernet business, with SLA and DBA support.
 - Features - 



1.Point-to-point network topology, effectively collect user scattered Ethernet business, and gather at the urban area network junction point, using GE interface to connect the upper equipment, to achieve smooth interconnection with the existing network.



2.The Dynamic Bandwidth Allocation Mechanism (DBA) enables all users to more reasonably share the bandwidth of 1Gbps, achieving reliable quality of service assurance (QoS)



3.Support expansion, support three-layer exchange capability



4.4*10G optical port up, 8*1G up



5.RSTP rapidly generates tree function guarantees the redundant connectivity of OLT and the backbone network.The EAPS fast loop protection protocol achieves 50ms high reliability



6.Network coverage radius: as far as 60 km



7.FC,CE,ROHS Certification



8.Support for IGMP multicast, the effective use of broadband.Support for multicast VLAN



9.Support for IPTV, voice, and data triple playback



10.Rich OAM functions, including configuration, alarm, performance monitoring, failure isolation, and security management, and support CLI and GUI two management methods, easy to learn and use
