OLT-1000 is an OLT device which complies with IEEE802.3ah and PRC communication industry standard (YD/T 1475-2006). When it works together with the P1004 ONU products, an efficient EPON solution can be established.
The modularized OLT supports the 1Gbps PON transmission rate. Its efficient bandwidth usage and Ethernet service supporting help carriers to provide reliable services to their users. 
Its coupling ratio, 1:64, and its support of different hybrid ONU networks minimize the carrier’s investment. OLT-1000 supports SLA and DBA.

Features
1.It adopts the point-to-multipoint network topology, effectively collects separate Ethernet services and aggregates them on the MAN node. 2.It connects the upper-layer devices through the GE interface and can be connected to the existing network smoothly.
3.The Dynamic Bandwidth Allocation (DBA) mechanism enables all users to share the 1Gbps bandwidth reasonably, guaranteeing a reliable QoS. 
4.The Rapid Spanning Tree Protocol (RSTP) enables the redundant interconnection between OLT and backbone network.
5.Support IGMP multicast and efficiently utilizes the bandwidth.
6.Support multicast VLAN.
7.Support broadcast of IPTV, voice and data simultaneously.
8.Support network management of inner bandwidth and outside bandwidth.
9.It has rich OAM functions such as configuration, alarm, performance monitoring, trouble isolation and security management. At the same time, it supports the CLI/GUI management, which is easy to use.
