METHOD FOR CHECKING FIBER-OPTIC TRANSMISSION SYSTEM

摘要

FIELD: optical communication systems. SUBSTANCE: method for serviceability check of fiber-optic branches of communication system includes recording of data on prediction of fiber-optic line condition in communication centers during transmission of probe signals between them. This condition is predicted by discounting minor. Fiber-optic communication system has definite power margin for transmitting optical component due to line degrading. Process of optical component decay in line varies with time and can exceed threshold value. EFFECT: enhanced survivability of fiber-optic communication system. 1 cl, 1 dwg
