Multichannel Optical Frequency Alignment Method and Multichannel Optical Frequency Alignment Method Using Optical Fiber Michelson Interferometer Type Optical Filter in Multichannel Optical Transmission System

摘要

In a multi-channel optical transmission system using optical frequency (or wavelength) division multiplexing, an optical filter composed of an optical fiber Michelson interferometer is used to set the multi-channel optical frequencies at pseudo-interval (or sequential boiling interval) Or sequential boiling interval) of the optical fiber, the crosstalk caused by the four-wave mixing of the optical fiber can be efficiently suppressed and a compatible system can be realized through efficient alignment of the multi-channel frequency Channel optical frequency alignment method and a multi-channel optical frequency alignment apparatus using an optical fiber Michelson interferometer type optical filter in a multi-channel optical transmission system.
