Abstract: |
The invention relates to the optical channel selection device based on the address control and belongs to the technical area of the optical channel selection, its features are as follows: optical division device which divides the optical packets into two channels; the photoelectrical conversion device converts one channel of the optical packet outputted by the optical division device into the telegraph and corresponding clock signals; channel selection logic control module extracts the address from the received telegraph and generates the control signals of all optical channels according to the address mapping relation of this device; the photoelectrical synchronization device receives another channel of optical packet of the optical division device and synchronizes the optical packet with the control signals entering into the optical channel via controlling the length of the optical fiber; the optical channel selection module is controlled by the control signals generated by the channel selection control module, when this address does not belong to the port of the current channel, the optical signals is refracted to other sites, otherwise, the optical signals smoothly pass. The invention can save the carrier wavelength resources, avoid the data error, is simple in structure and quick in channel selection. |
