4-Channel Telephone Optical Terminal Overview
The IDM-NT104 Telephone Optical Terminal extends voice and data services to various subscriber areas, serving as a replacement for remote small exchanges, enabling cross-boundary subscriber provisioning, and alleviating the load on switching offices; alternatively, it resolves the constraints of twisted-pair cabling in bandwidth and transmission distance within urban areas, expanding the service coverage of switching offices. This device can be widely applied in public telephone network access and dedicated line information transmission for telecommunications data services, electric power, banking, public security, military, schools, highways, and other sectors.
