Description

[Technical field]

[0001] The present invention relates to an optical transmission system for optically transmitting an analog video signal or a digital video signal between an optical base station and an optical camera adapter. [Background technology]

[0002] The video signal of the image captured by the video camera is sent to a video switcher or the like via a transmission cable, but if these devices are installed far away, it is difficult to transmit the electrical signal without attenuating it. Therefore, long-distance transmission is achieved by converting the electrical signal into an optical signal at the video camera, transmitting this optical signal via an optical transmission cable, and then converting the optical signal back into an electrical signal at the remote device (for example, Patent Document 1).
