A compatible camera to the new interface: OPT-C: Link. OPT-C: Link solved the weak point of the “CameraLink,” which is having the difficulty in applying in the environment affected by the transmission distance limitation and noise influence. It enables long-distance transmission (150 m) of large capacity image data. Transfer speed supports 1ch: 6.25 Gbps communication speed. It is resistant to noise. Image data and control signal can be realized by the same optical communication, and it contributes to wiring saving.
