L3 Gepon OLT

SSS-OLT-L3 Series ::



Overview ::

SSS-OLT-L3 Series OLT complies with IEEE802.3ah and PRC communication standard (YD/T 1475-2006), supports CTC2.1/3.0, automatically detects and is compatible with other manufacturers’ ONUs, so P3600 series can be used in an efficient EPON solution. This series includes three models: SSS-OLT-L3-8P-8S, SSS-OLT-L3-12P-8S and SSS-OLT-L3-16P-8S.



SSS-OLT-L3 OLT supports the 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-L3, 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.
