GP2101

• The point to multi-point network topology is adopted to effectively collect and aggregate the scattered Ethernet services of users,

and the 10 / 100 / 1000m ethernet standard RJ45 interface is provided on the user side;

• Dynamic bandwidth allocation mechanism enables all users to share 2.5Gbps bandwidth more reasonably, realize reliable

quality of service (QoS), and ensure the quality of different services in the same network;

• Support IGMP multi-cast and make effective use of broadband;

• Support multi-cast VLAN;

• GPON or EPON up-link is adopted to meet ITU-T g.984/g.988 standards;

• Provide remote management through OLT and support local console management;

• Support the line loopback detection function of Ethernet interface on user side;

• Support IEEE 802.1Q VLAN protocol;

• Support broadcast storm suppression;

• Support PPPoE routing function.
