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-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).
• Gigabit Ethernet over SDH (STM-1) – Available bandwidth on a single Ethernet port on an STM-1 link is 137Mbps.
• 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.

Ethernet over T1 is an Ethernet extension device utilizing TDM telecom infrastructure (of T1, DS3, SDH or microwave links carrying T1s ). It converts the Ethernet data into T1 frame format for transmission over the existing TDM (T1) links and then re-converts the T1 back into Ethernet data the far-end terminal, to BRIDGE two Ethernet LANs over the existing T1-based telecom network. The device can effectively utilize the existing TDM network to transport Ethernet data with low investment.
