Background
AWG-CWDM4 is the preferred technique in dense Wavelength Division Multiplexing (WDM) systems, where a set of arrayed waveguides with equal length difference form a grating, using the ability to split waves. The principle is that after multiplexed signal light containing a plurality of wavelengths is output through a central input channel waveguide, the multiplexed signal light is diffracted in an input flat waveguide, reaches an input concave grating for power distribution, and is coupled to enter an array waveguide area. Since the arrayed waveguide end surface is located on the circumference of the grating circle, the diffracted lights arrive at the arrayed waveguide end surface with the same phase. After being transmitted by the arrayed waveguide, because the adjacent arrayed waveguides keep the same length difference Delta L, the output light of a certain wavelength of the adjacent arrayed waveguides on the output concave grating has the same phase difference, the phase difference is different for the light of different wavelengths, so the light of different wavelengths is diffracted and focused to different output channel waveguide positions in the output flat waveguide, the wavelength distribution, namely demultiplexing function is completed after the light of the output channel waveguide is output, and the optical fiber connector is a device for detachably (movably) connecting the optical fiber and the optical fiber, and precisely butt-joints two end faces of the optical fiber, so that the light energy output by the transmitting optical fiber can be coupled into the receiving optical fiber to the maximum extent, and the influence on a system caused by the optical fiber intervening between the optical fiber and the optical fiber is minimized, which is the basic requirement of the optical fiber connector. To a certain extent, the optical fiber connector affects the reliability and various performances of an optical transmission system, the optical fiber connector is applied to the field of 100G high-speed optical modules at present less, and the working connection mode and the signal processing mode are old and cannot keep up with the current high-speed data processing.
