Console & SNMP managed GE over STM-1 converter

EOS Product Overview:
WY-155GE Gigabit Ethernet over SDH (STM-1) provides a simple, cost effective and compact solution to convert 10/100/1000Base-T (Gigabit) data interface on the user side and transport Ethernet traffic over a STM-1 (155Mbps) SDH link and reconstruct the data back to ethernet frame format, at remote end. The converter is an effective method for converting and transporting 10/100/1000Base-T (Gigabit) ethernet data over an STM-1 (155Mbps) SDH link. This Gigabit 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 application to provide a compact, cost effective and flexible solution to deliver multiple Ethernet channels.

Gigabit Ethernet interface card 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 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 SDH transmission network.

The unit is available in a compact 1U (44mm high) box in a 19-inch rack mount chassis.
