Embodiment Construction
[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention.
[0028] The present invention provides an adjustable small wavelength interval optical transceiver, whose working principle is to replace the traditional spatial optical comb filter with a comb filter based on PLC, and change the wavelength of the laser by changing the temperature inside the laser transmitter , so that it can be used in conjunction with the comb filter to complete dual multiplexing, so that the light at the transmitting end can pass through the filter and enter the single-mode fiber, and prevent the received optical signal from entering the optical transmitting end, while preventing the optical signal at the local transmitting end from directly Enter the local receiving end to cause optical crosstalk problems.
[0029] The present invention will be described in...
