Phase distortion is a major factor in disrupting the quality and efficiency of fiber optic transceivers. It is necessary to analyze and systematize the phase distortions introduced into the receiving/transmitting channel. Also the actual problem is considering methods to reduce them.

The goal of the article is to show that phase delays have an analytical expression and can be taken into account when calculating phase distortions in microwave signal transmission systems over optical fiber.

The research has shown that almost all phase distortions can be modeled or experimentally taken into account in each specific fiber-optic communication line and software and hardware solutions can be provided to reduce such distortions.

The study of phase distortions will allow for higher signal processing accuracy, and improve the quality and efficiency of fiber-optic transceiver paths.
