STM-1 (Optical /
Electrical) Add-Drop Multiplexer (with upto
16 E1 & 4 Ethernet Interfaces)
Product Overview
Orion's STM-1, Multi-Service SDH Transmission
Equipment is a modular platform with two pluggable
155.52Mbps optical interfaces which may be used in an
add-drop (drop-insert) or a point-to-point application
to provide a compact, cost effective and flexible
multi-service platform to deliver E1 and Ethernet
channels.
Interface card options such as the E1 interface card,
4x100BaseT Ethernet interface card 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. The Orion's
STM-1, E1, Ethernet and GigaBit Multi-Service 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 or a ring (add-drop) SDH transmission network.
