SDH STM-1 Multiplexer

6-optical-port, STM-1 MADM or TM multiplexer,support up to 231 E1-circuit add/drop

                           ZS-OS155-SHELF SDH/MSTP Chassis STM-1 Device

Overview 

ZS-OS155-Shelf is a STM-1 optical transmission system, whose technical performances fully comply with ITU-T and ETSI standards. The system provides up to 6 155Mb/s aggregate optical interfaces, complete synchronous timing features and a powerful non-blocking cross connection matrix. It can be used for building point-to-point, chain, star or ring networks, with SNCP features, serving departments of Telecom, Traffic or Energy industry, etc. Applications OS155-Shelf are:

 ·        Cross MUX, becoming the transmission network hinge, capable of providing up to 6 155Mb/s optical ports, 210 E1 add/drop multiplexing, both high-order and low-order signals can be non-blocking cross-connected;

 ·       TM, becoming transmission module of a large exchanger, multiplexing 231 E1, and providing 1+1 channel protection to each E1;

 ·    Optical Ethernet bridge, becoming centralized access equipment of WAN, realizing remote connection of 88 links of 10/100M Ethernet through E1;
