Description
Technical field: [0001] The invention relates to a control circuit of optical communication waves, in particular to a wavelength control circuit in optical communication wavelength division multiplexing equipment. Background technique [0002] Wavelength division multiplexing (WDM) is to combine two or more optical carrier signals of different wavelengths (carrying various information) at the sending end through a multiplexer (also known as a multiplexer, Multiplexer) and couple them to the optical The technology of transmitting in the same optical fiber of the line; at the receiving end, the optical carriers of various wavelengths are separated by a demultiplexer (also known as a demultiplexer or a demultiplexer, Demultiplexer), and then the optical receiver is used as a further processing to recover the original signal. This technology of simultaneously transmitting two or more optical signals of different wavelengths in the same optical fiber is called wavelength divisio...
