What is the IDM-VNT2204 Multi-service Video Optical Terminal? What Services Can Be Transmitted over One Fiber?

The primary function of the IDM-VNT2204 multi-service video optical terminal is to multiplex video, Ethernet, voice, and low-speed data into a single optical fiber for transmission, and then restore them into various service interfaces at the remote end, eliminating the need to stack multiple single-function devices at the site. Its service composition includes: 2 channels of one-way standard-definition video, which can also be configured as 1 channel of bidirectional video, compatible with NTSC, PAL, and SECAM standards, supporting high-quality transmission of any high-resolution static and dynamic images; 2 groups of Ethernet each sharing 100M line-rate bandwidth, totaling 200M over the fiber; 4 voice interfaces, which can connect telephones or EM2/4-wire audio, with 2 channels being automatic telephone services; plus 2 RS232/RS485 interfaces and 1 channel of control data.
