IDM-MUX60 60-Channel SDH Telephone Optical Terminal

Overview

The IDM MUX60 is a multi-service SDH access device with SDH technology at its core and STM-1 level, fully compliant with ITU-T standards. This device provides users with multi-service access and SDH optical transmission, offering two 155.52Mbps optical interfaces (A and B), four 10M/100M Ethernet interfaces, multiple groups of E1 interfaces, and 64K services. It features network element timing per ITU-T G.813 standards, VC-12 cross-connection, and channel protection functions. In addition, the IDM MUX90 is used to build point-to-point, point-to-multipoint chain and ring transmission networks. The IDM MUX60 multi-service access platform can be widely applied in telecommunications data services, power, banking, public security, military and other sectors for public telephone network access or private line information transmission.

Product Features
