The light beam is an electromagnetic signal with a frequency in the range of 10^14 to 10^15 Hertz.

Optical fibres are difficult to tamper with (to monitor or inject data in the middle of a connection), making them appropriate for secure communications. The light beams do not escape from the medium because the material used provides total internal reflection. See also FDDI, Optical Carrier n, SONET.
