GR4000 Series IPv4/IPv6 Gigabit Core Routers

GR4000 series routers are IPv4/IPv6 high-end core routers for high-reliability IP/Ethernet networks. GR4000's emphasis is on providing high-speed interfaces, such as 1G/10G Ethernet and OC-192/OC-48 POS. Switching performance ranges from 96 to 384Gbps, supports rich IPv6 protocols, IPv4/IPv6 dual stack and tunnel technology.

Offering carrier-grade structure, such as AC/DC power flexibility, full redundancy and unsurpassed port density. GR4000 series can meet carrier/ISP requisite application well.
High-end core routers and aggregation routers orienting to backbone networks
Edge routers and aggregation routers orienting to access network (especially GbE accommodation)



GS4000 Series IPv4/IPv6 Gigabit Core Switches

GS4000 series is high-end core switches for high-reliability IP/Ethernet networks .Switching performance of 5 models ranges from 96 to 384Gbps, supports rich IPv6 protocols, IPv4/IPv6 dual stack and tunnel technology.

Offering carrier-grate structure, such as AC/DC power flexibility, full redundancy and unsurpassed port density. GS4000 series can meet your requisite application well.
