Gigabit Ethernet
over STM-1 (SDH) Converters |
Description Valiant’s 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.
Valiant's 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 hannels.
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. Valiant’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.
The unit is available in a compact 1U (44mm
high) box in a 19-inch rack mount chassis.
