Product information:

Extralink OLT 4GE 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.
Extralink OLT 4GE supports the symmetric uplink/downlink1.25Gbps PON transmission rate, efficient bandwidth usage and Ethernetservices, helping carriers to provide reliable services to their users Its coupling ratio, 1:64, and its support ofdifferent hybrid ONU networks minimize the carrier’s investment.
OLT 4GE has strong functions and QoS guarantee ,and supports SLA and DBA.
