Ethernet over SDH (STM-1) Converters

Product Overview

Orion Telecom Networks Inc. offers Ethernet over SDH (STM-1) / Ethernet over TDM,  (EoS), 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.

Available in 2 versions:

  • Ethernet over SDH (STM-1) – Available bandwidth on a single Ethernet port on an STM-1 link, is 140Mbps

  • Gigabit Ethernet over SDH (STM-1/4) – Available bandwidth on a single Ethernet port on an STM-4 link is 622Mbps (up to 1000Mbps on 2 x bonded STM-4 links).

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. Orion’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.
