- EPON: FB-E-OLT-4PON-6GE supports IEEE802.3ah and PRC Community Industry Standard (YD/T 1475-2006).
- System’s capacity: The modularized PON card of FB-E-OLT-4PON-6GE can support four EPON systems simultaneously, up to 256 ONUs and the 1/64 coupling ratio.
- Uplink interface: Its flexible design supports various MAN interface type groups. The optical ports or the electrical ports are selected according to network conditions.
- Device size: A 1U device occupies a little space and consumes little power, decreasing the function cost of the services.
- Protecting the bus optical fiber: FB-E-OLT-4PON-6GE supports that the link can be automatically switched to protect the optical fiber when trouble occurs in the optical fiber.
- It is highly reliable and powered by two power sources.
- FB-E-OLT-4PON-6GE complies with IEEE802.3ah and P.R.C intercommunication standard, YD/T 1475-2006, supports CTC20/2.1, automatically discovers and cooperates with ONUs of different manufacturers.
- FB-E-OLT-4PON-6GE OLT supports the symmetric uplink/downlink 1.25Gbps PON transmission rate, efficient bandwidth usage and Ethernet services, helping 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.
- FB-E-OLT-4PON-6GE , based on the edge-cutting technologies, is strong in functions. A few of its functions such as QoS guarantee, SLA and DBA can be easily listed out.
- It adopts the point-to-multipoint network topology, effectively collects separate Ethernet services and aggregates them on the MAN node. It connects the upper-layer devices through the GE interface and can be connected to the existing network smoothly.
- The Dynamic Bandwidth Allocation (DBA) mechanism enables all users to share the 1Gbps bandwidth reasonably, guaranteeing a reliable QoS.
- The Rapid Spanning Tree Protocol (RSTP) enables the redundant interconnection between OLT and backbone network, while EAPS provides highly reliable 50ms ring.
- They support the IGMP multicast and efficiently utilize the bandwidth. They support the multicast VLAN.
- It supports the broadcast of IPTV, voice and data simultaneously.
- 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.
