Home / What is the principle behind optical fiber encryption

Optical encryption is a means of securing all in-flight data in the optical transport layer of the network by transforming the data using an algorithm (cipher) to make it unreadable to anyone except those possessing special knowledge (key), as it is carried over wavelengths across. Advanced tapping techniques allow attackers to intercept data by bending or micro-cutting fiber, extracting part of the optical signal without disrupting service. Unlike encryption methods used at higher network layers, optical encryption works directly at the transmission level. Optical fiber is a key technology in the modern world of communication, playing a crucial role in the secure transmission of data.
