Gigabit Ethernet over SDH (GigE) / Gigabit Ethernet over STM-4 Converter
Orion'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).
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.
