An optical fiber, or optical fibre, is a flexible glass or plastic fiber that can transmit light [a] from one end to the other. Such fibers find wide usage in fiber-optic communications , where they permit transmission over longer distances and at higher bandwidths (data transfer rates) than electrical cables.
A TOSLINK optical fiber cable with a clear jacket. These cables are used mainly for digital audio connections between devices. A fiber-optic cable, also known as an optical-fiber cable, is an assembly similar to an electrical cable but containing one or more optical fibers that are used to carry light.
Long-range optical wireless communication or free-space optical communication (FSO) is an optical communication technology that uses light propagating in free space to wirelessly transmit data for telecommunications or computer networking over long distances. "Free space" means air, outer space, vacuum, or something similar.
SkyWrap fibre-optic cable installation Optical attached cable ( OPAC ) is a type of fibre-optic cable that is installed by being attached to a host conductor along overhead power lines . The attachment system varies and can include wrapping, lashing or clipping the fibre-optic cable to the host.
ITU-T G.651, "Characteristics of a 50/125 μm multimode graded index optical fibre cable" ITU-T G.652, "Characteristics of a single-mode optical fibre cable" Other standards specify performance criteria for fiber, transmitters, and receivers to be used together in conforming systems. Some of these standards are: 100 Gigabit Ethernet
OC-3c (c stands for "concatenated") concatenates three STS-1 (OC-1) frames into a single OC-3 look alike stream. The three STS-1 (OC-1) streams interleave with each other so that the first column is from the first stream, the second column is from the second stream, and the third is from the third stream.

Fiber to the x (FTTX; also spelled "fibre") or fiber in the loop is a generic term for any broadband network architecture using optical fiber to provide all or part of the local loop used for last mile telecommunications. As fiber optic cables are able to carry much more data than copper cables, especially over long distances, copper telephone ...
