STM-1 63 E1 (Optical / Electrical) Add-Drop SDH Multiplexer
Product Overview
Orion Telecom Networks Inc. offers STM-1 63 E1 (Optical / Electrical),
Add-Drop SDH Multiplexer unit is a
modular platform unit with two 155.52Mbps optical /
electrical interfaces, which may be used in a
point-to-point, chain or ring application to provide an
ultra-compact, cost effective and flexible multi-service
platform.
63xE1 interfaces (120 Ohms [RJ-45]
and 75 Ohms [BNC] 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, SDH
Transmission Equipment provides full capability to
cross-connect at E1 level between all tributaries.
The equipment can be used as Terminal
Multiplexer (TM) or an Add-Drop-Multiplexer (ADM) to
build a point-to-point, ring and chain (add-drop)
transmission network.
