IDM-NT104 Desktop 4-Port Telephone Optical Terminal
The IDM-NT104 Desktop 4-Port Telephone Optical Terminal features a compact desktop chassis design. It provides 4 telephone interfaces and 1 100M high-speed Ethernet interface via a single optical channel. This device extends voice and data services to remote user areas, effectively replacing remote small exchanges, enabling cross-boundary number allocation, and alleviating pressure on central switching offices. It also resolves bandwidth and transmission distance limitations of twisted-pair cables in urban areas, expanding the service coverage of switching offices. Widely applicable in telecommunications, data services, power, banking, public security, military, education, expressway, and other sectors for public telephone network access and dedicated line information transmission.
