4 or 8 PON OLT Layer 2 ::



SSS-OLT-4P-4S-L2 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.

SSS-OLT-4P-4S-L2 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.

SSS-OLT-4P-4S-L2, 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.

SSS-OLT-4P-4S-L2 can support four PON systems and has the following advantages:

EPON: SSS-OLT-4P-4S-L2 supports IEEE802.3ah and PRC Community Industry Standard (YD/T 1475-2006). 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. 

System’s capacity: The modularized PON card of BDCOM P3310B 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.

They support the IGMP multicast and efficiently utilize the bandwidth. They support the multicast VLAN.

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: BDCOM P3310B 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. 
 
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.
