Configuration of 8K camera optical fiber transmission system
AT-4820/AR-4821
Camera Adapter / Base Station
Outline of product
The signal of various devices such as the signal of the shoulder type and the handy type camera recorder is transmitted by the optical fiber cable.
A single optical fiber cable enables long-distance transmission of camera video signals, microphone audio, AES/EBU, return signals, tally signals, intercams, camera remote controls, genlock signals, and LANs required for system cameras (studios).
