Industrial Automatic Control Systems and Controllers Annotation << Back Reliability Models for Fiber Optic Information Transmission Systems Based on Distribution Laws Juraeva N.I. The article examines various distribution laws for hardware and software, which allows for considering their specific characteristics and improving the overall reliability of the system. The obtained results showed that integrating different distribution models signifi cantly improves failure prediction and contributes to the development of more robust fi ber-optic systems. Keywords: reliability, fi ber optic information transmission systems, distribution laws, distribution density. DOI: 10.25791/asu.1.2025.1560 Pp. 52-56.
