The digital video optical terminal is an advanced fiber optic transmission device that can integrate and transmit multiple signals such as video, data, and audio over long distances. The device provides a variety of interfaces and configuration options, supporting different signal formats and transmission distances. This user manual describes the 4-channel video optical terminal as an example.
The 4‑channel video optical transceiver integrates video, data, audio and Ethernet signals for long‑distance fiber transmission. It supports PAL, NTSC and SECAM composite video formats, offers a video bandwidth of 5‑10 MHz, and provides up to 120 km transmission distance on single‑mode fiber without repeaters.
The manual details unpacking, power connection, panel functions, video and data interface wiring, and installation steps. It also includes troubleshooting guidance and technical support information for reliable operation. This manual is written in Chinese.
