4 To 24 STM1 Sonet Fiber Optical Network Series Add / Drop Modular
Compact 1U Design
Overview
Global Tech economic multi-service SDH is fully compliant with
ITU-T and China domestic SDH standard, and can benefit your network
with compact design, flexible topology and intelligent
architecture. GT-SDH-155B provides two STM-1 optical line
interfaces, versatile E1, V.35,Gigabit Ethernet and FE multiplexing
and transmission, ITU-T G.813 compliant NE timing, VC-12 level
switching and path protection mechanism. GT-SDH-155B can operate as
ADM or TM to construct point-to-point, chain and ring networks.
