Resilient fiber optic infrastructure
Spurný, Vladimír ; Kubánková, Anna (referee) ; Münster, Petr (advisor)
Optical networks are often mistaken for being secure, but there are ways to eavesdrop on the signal in an optical fiber without the user noticing. Cryptography is used to protect data, but quantum computing may threaten current encryption methods in the future. Misuse of active and passive elements affect the security of the optical infrastructure. The monitoring ports of active devices and the physical properties of optical fibre s pose risks for data leakage and eavesdropping. This work focuses on information transmission in optical fibers, data leakage risk analysis, and testbed design for measuring data signal interference. And then verifies the functionality of the workstation on a high-speed coherent transmission system.
