The remote device housing 1 provides 1×12G SDI input and can also receive fiber optic input from a camera control unit. The near-end device housing 3 can achieve 2×12G SDI output. The data section provides 1×RS-422 serial communication, GPIO, Gigabit Ethernet, synchronization, and timecode transmission, suitable for the comprehensive transmission of video and control signals from various camera control units. This utility model comes with a wide variety of installation accessories, allowing for installation and use in various shooting environments such as tripods, walls, and even ceilings. This utility model can be used with ordinary single-mode fiber optic connections or with camera composite fiber optic cables. When using a camera composite fiber optic cable connection, the near-end device housing 3 can provide long-distance power to the remote device housing 1. The remote device housing 1 has an SDI fiber optic signal input, which can transmit the camera control unit's fiber optic signal or other SDI optical signals to the near-end device housing 3, converting them into SDI signal outputs. This utility model incorporates a mainstream device protocol library, is compatible with various mainstream devices, and adopts bidirectional CWDM optical transmission technology. It supports bidirectional transmission of video and control signals over a single fiber, solving the problems of low efficiency and complex wiring in traditional unidirectional transmission.
