Gigabit Ethernet over SDH |
Product Overview
Orion Telecom Networks Inc. offers 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. Orion’s 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.
