Overview

The IDM MUX180 Optical-Electrical Integrated Transmission Equipment is a new-generation integrated transmission device developed by our company, based on MSTP and PCM technologies. It integrates MSTP transmission and PCM multi-service access functions into one unit, meeting the diverse requirements of users for broadband and narrowband service transmission and access over optical fiber. With SDH ring network protection, it provides more reliable communication protection. The IDM MUX180 integrated unit can directly connect remote telephones, computers, cameras, and other terminals. At the remote end, it can also be extended via optical ports to connect PDH optical terminals, optical modems, and multi-service optical terminals, adapting to various network topologies.
