Embodiment Construction
[0021] A wavelength division ring video optical transceiver is characterized in that it consists of a central office device mainly composed of an optical receiver, a wavelength division multiplexer and a data processing module, and at most eight optical transmitters, an optical coupler and a wave It is composed of multiplexers, placed in different positions, remote equipment that transmits video signals of different wavelengths and connected by optical fibers, through the wavelength division multiplexer in the remote equipment, the video signal to be transmitted is converted into a single wavelength At the same time, the wavelength is multiplexed into the optical fiber for transmission, so that the beams of different wavelengths are multiplexed into one optical fiber at different positions along the road. Specific embodiments of the present invention, by Figure 4 As shown, one central office device is the optical receiving device and 8 remote devices are the optical transmitt...
