IDM-NT008
The IDM-NT008 Desktop 8-Channel Multi-Service Optical Multiplexer provides 8 telephone interfaces through 1 optical fiber channel. The 8-channel telephone optical multiplexer features high integration and compact size. It extends voice and data services to various user areas, enabling cross-boundary number assignment, serving as a substitute for remote small exchanges, and postponing the construction of switching offices. Alternatively, in urban areas, it overcomes the limitations of twisted pair in terms of frequency band and transmission distance, expanding the service range of switching offices.
