WY-155FE Ethernet over STM-1 Converter, SDH Multiplexer
Ethernet over STM-1 / SDH (EoS) Converter
This 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. Our 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.
