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. Unlike encryption methods used at higher network layers, optical encryption works directly at the transmission level. Optical fibers are thin strands of glass or plastic that carry data as light signals. Some of the most significant threats include: To protect data transmitted over optical networks, encryption is used to scramble the data, making it unintelligible to unauthorized parties. They offer many advantages over other types of cables, such as copper wires, coaxial cables, or wireless signals.
