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...

Abstract

The invention discloses a wavelength-division ring video optical transmitter and receiver. The wavelength-division ring video optical transmitter and receiver is characterized by being formed by connecting a local terminal device mainly consisting of an optical receiver, a wavelength division demultiplexer and data processing modules, at most 8 remote terminal devices which mainly consist of an optical transmitter, an optical coupler and the wavelength division multiplexer, are arranged in different positions and transmitting different wavelength video signals over optical fiber; and converting the video signals to be transmitted into single wavelength signals and multiplexing the wavelength into the optical fiber for transmission, thus causing light beams with different wavelength to be multiplexed into one optical fiber at different positions along a path. The invention provides a concept of multiplexing along a path to manufacture a single wavelength multiplexing device, which causes various light beams with different wavelength to be multiplexed into the one fiber at different positions along a path, and provides a particular chain protection mode and a particular ring protection mode to achieve timely and accurate signal transmission between a receiving station and a transmitting station.

Description

technical field [0001] The invention relates to an optical transmission equipment wavelength division ring video optical transceiver capable of transmitting video, voice and control data, which adopts multiplexing along the road and has a unique ring protection function, and belongs to the field of communication technology. Background technique [0002] Coarse Wavelength Division Multiplexing CWDM (Coarse Wavelength Division Multiplexing) and Dense Wavelength Division Multiplexing DWDM (Dense Wavelength Division Multiplexing) are to multiplex (Mux) light beams of different wavelengths into a single optical fiber for transmission, and at the other end of the transmission, then Demultiplexing (DeMux) separates beams of different wavelengths (such as figure 1 shown). Each wavelength beam can carry different services independently, so that the bandwidth of a single optical fiber transmission can be multiplied according to the number of beams of different wavelengths. Passive c...
