IDM Field Optical Transmission Equipment

The IDM Field Optical Fiber Integrated Access Terminal is a new generation of optical fiber integrated service transmission equipment. Developed with internationally advanced integrated circuits, programmable logic circuits, and high-speed microprocessors, this equipment aggregates voice, low-speed data, and video signals into a standard 2M interface through various service interface cards, and then multiplexes the 2M signal, video signals, transparent E1 signals, and line-rate 100M Ethernet signals into a 1.25G optical transmission channel for transmission using time-division multiplexing technology.

Currently, this equipment can transmit 2 channels of bidirectional video, 2 channels of E1, 2 channels of bidirectional high-fidelity audio, 4 channels of shared 100M Ethernet, 4 channels of ordinary telephone, 2 channels of magneto telephone, and 2 channels of RS485 data services over a single optical fiber. According to actual requirements, the equipment can also provide service interfaces such as V.24 (RS232), V.35, 10Base-T, co-directional 64K, 2/4-wire audio, and hotline telephone. Additional service interfaces can be added without changing the optical fiber capacity.
