Fiberbit's 4 PON port EPON OLT get's installed in center - POP's and NOC's, where core IP and phone network connections are available. Looking for something more sophisticated and features rich than just simple bridging from OLT's to ONU's? More than 1 - 2 OLT ports? Then this OLT is for you. 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.
Small and mid sized and big ISP's;
Regional level carriers who want to organize fast development of FTTH access
Hotels and resorts who want to establish triple play over a fiber
Local Area Networks;
CCTV IP camera surveillance
Below you can see 1 common scenario - suburban household connected by EPON OLT in center and various ONU's at the CPE - user side.
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.
1.25g fiber transceiver module,20 km distance, 1310 nm FP TX, 0~70℃, single mode, DDM as option, industrial type -40 to +85°C as option.

Modern networks rarely rely on pure topologies like bus, ring, or star. Most common solutions use hybrid topologies, which are combinations of features from those three.
As it is clear from the name, star-wired ring topology has features of star and ring topologies. You can see example of this topology ...
