IDM-NT202
The IDM-NT202 multi-service optical terminal features a 19-inch 3U rack-mount chassis design; provides 16 dual-fiber (single-fiber) optical channels; the IDM-NT202 multi-service optical terminal offers 2 ordinary telephone interfaces with Caller ID and 2 groups of shared 100M Ethernet channels, and the 2 groups of Ethernet interfaces can be arbitrarily divided into VLANs; equipped with comprehensive alarm indication functions; dual power supply units with 1+1 mutual backup.
Overview:
The IDM-NT202 centralized Telephone Optical Terminal extends voice and data services to various subscriber areas, serving as a substitute for remote small exchanges, enabling cross-boundary subscriber provisioning, and alleviating the load on switching offices; alternatively, it resolves the constraints of twisted-pair copper cables in terms of bandwidth and transmission distance within urban areas, thereby expanding the service coverage of switching offices. The NT202 centralized telephone optical terminal 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.
