[0001] The utility model relates to the field of optical wavelength division multiplexing devices, in particular to a polarization-adjusted optical wavelength division multiplexing device. Background Technique

[0002] The optical wavelength division multiplexing device is a key device for realizing the optical wavelength division multiplexing technology. Its main function is to combine (multiplex) optical signals of different wavelengths at the sending end and couple them into the same optical fiber on the optical cable line for transmission. At the receiving end, the device will separate (demultiplex) the combined-wavelength optical signals and perform further processing to restore the original signals and then send them to different terminals. The application of the optical wavelength division multiplexing device can bring many advantages, such as increasing the transmission capacity of the optical fiber, improving the signal compatibility, being flexible to use, and reducing the operation cost, etc. In the existing optical wavelength division multiplexing device, during the use process, since the polarization adjustment is manual adjustment, when external physical interference occurs during signal transmission, it cannot be processed in time, resulting in signal disconnection and reducing the overall adjustment effect. Therefore, we propose a polarization-adjusted optical wavelength division multiplexing device to solve the problems mentioned above. Content of the Utility Model
