Turgunov Bekzod Abdivositovich, Orifjonova Durdona Vohidjon Qizi, Mamirho’jayev Muxammadamin Mavlonbek o’g


This article analyzes the reasons for the failure of semiconductor laser diodes. Also, based on the experimental results, a mathematical model of the process of degradation in power of DFB-type laser diodes, widely used in optical communication systems, will be developed.


Optical communication systems, degradation, reliability, wavelength division multiplexed optical communication systems, approximation.
