Description

Valiant's Gigabit Ethernet over SDH (STM-4) Equipment is a compact and high-performance Gigabit Ethernet to STM-4 converter (with VLAN TAG function), which offers three Gigabit Ethernet interfaces (2 Electrical and 1 Optical Ethernet interfaces) and 2 x STM-4 interfaces.

The solution complies to ITU-T G.7041 and G.7042 EoSDH (Ethernet over SDH) technology. All VC4 / STM-1 (1~8) are user configurable and may be mapped to a single VCG (single Ethernet Port), when both STM-4 interfaces are independent. 3 x Gigabit Ethernet interfaces can share up to 1112Mbps (8 VC4).

Available in 3 versions:

Gigabit Ethernet over SDH (STM-1) – Available bandwidth on a single Ethernet port on an STM-1 link is 137Mbps.
Gigabit Ethernet over SDH (STM-4) – Available bandwidth on a single Ethernet port on an STM-4 link is 622Mbps (up to 1000Mbps on 2 x bonded STM-4 links).
Ethernet over SDH (STM-1) – Available bandwidth on four Ethernet ports (4VCG) on an STM-1 link (126Mbps bandwidth aggregated on 4 Ethernet ports).

This equipment offers low power consumption, high integration and supports point-to-point application. This is a cost-competitive solution for applications such as network access, transparent LAN services and LAN extension.
