Ethernet over SDH (STM-1) / EoS Converters
Description
Orions’s Ethernet over SDH / STM-1 (EoS) provides a simple, cost effective and compact solution to convert 10/100BaseT data interface on the user side and transport Ethernet traffic over a STM-1 SDH link and reconstruct the data back to ethernet frame format, at remote end. The converter is an effective method for converting and transporting 10/100BaseT ethernet data over an STM-1 (SDH) link. Valiant is available in a 1U (44mm high) box in a 19-inch rack mount chassis.

Power Point Presentation (PPS)
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).
Orion's Ethernet over SDH (STM-1) Equipment is a modular platform unit with two pluggable 155.52Mbps optical / electrical interfaces, which may be used in a point-to-point, chain or ring application to provide a compact, cost effective and flexible solution to deliver multiple Ethernet channels.
Interface card options include the 4x100BaseT Ethernet interface card (1 VCG, 4 Ports 1 Channel), 4x100BaseT Ethernet interface card (4 VCG, 4 Ports 4 Channels) and Gigabit Ethernet interface card options along with Engineering Order Wire is available. The user removable / replaceable STM-1 Optical / Electrical interface option makes it easy to meet various and changing user requirements. Valiant’s STM-1, Ethernet and Gigabit Ethernet over SDH Transmission Equipment provides full capability to cross-connect at E1 level between all tributaries. The equipment can be used as Terminal Multiplexer (TM) to build a point-to-point, chain or ring SDH transmission network.
