The BT-125G is an FTTH GPON optical network unit with high performance and low power consumption. It provides subscribers with multicast services and enables their access to Internet to cater for the broadband access demands of families.
The BT-125G supports the functions as follows:
1.Uses GPON uplink that is compliant with ITU-T G. 984 series of standards;
2.Supports the configuration of Ethernet interface rates, working modes, MDI/ MDIX auto-negotiation mode, and Pause flow control;
3.Supports packet filtering and protection against illegal message attacks: suppresses unknown unicast, multicast and broadcast packets;
4.Provides performance statistics on all Ethernet lines;
5.Supports IGMP snooping protocol;
6.Supports the L2 wire speed forwarding;
7.Supports the WEB configuration function;
8.Supports the AES-128 algorithm for data encryption of downlink data;
9.Performs various QoS functions: supporting global configuration of queue priority and flexible mapping of 802. 1p value of packets;
10.Supports the PQ queue scheduling mode;
