CHARACTERISTIC PARAMETER MONITORING METHOD AND APPARATUS FOR SPACE DIVISION MULTIPLEXING OPTICAL FIBER, AND DEVICE AND STORAGE MEDIUM

摘要

Disclosed are a characteristic parameter monitoring method and apparatus for a space division multiplexing optical fiber, and a device and a storage medium. The method comprises: acquiring a time-domain coefficient of each sub-filter of a multiple-input-multiple-output (MIMO) equalizer; acquiring a frequency response of each sub-filter according to the time-domain coefficient of each sub-filter, so as to obtain a frequency response matrix of the MIMO equalizer; and acquiring, according to the frequency response matrix, a characteristic parameter of a space division multiplexing optical fiber in each space channel.
