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. The optical fiber elements are typically individually coated with plastic layers and contained in a protective tube suitable for the environment where the cable is used.

This is a list of domestic submarine communications cables and does not include international cable systems. All the cable systems listed below have landing points within one country, and are currently (as of August 2007) in-service. Several older cables, although no longer used for telecommunications, are used for scientific purposes.
All cables presently in service use fiber optic technology. Many cables terminate in Newfoundland and Ireland, which lie on the great circle route from London, UK to New York City, US. There has been a succession of newer transatlantic cable systems. All recent systems have used fiber optic transmission, and a self-healing ring topology.
A cable reel trailer with conduit that can carry optical fiber Multi-mode optical fiber in an underground service pit. An optical fiber cable consists of a core, cladding, and a buffer (a protective outer coating), in which the cladding guides the light along the core by using the method of total internal reflection.
Fibre-optic Link Around the Globe (FLAG) is a 28,000-kilometre-long (17,398 mi; 15,119 nmi) fibre optic mostly-submarine communications cable that connects the United Kingdom, Japan, India, and many places in between. The cable is operated by Global Cloud Xchange, a subsidiary of RCOM. [1]
The Americas Region Caribbean Ring System (ARCOS-1) is a fiber optic submarine communications cable of 8,400 kilometers that extends between the United States, the Bahamas, the Turks and Caicos Islands, the Dominican Republic, Puerto Rico, Curaçao, Venezuela, Colombia, Panama, Costa Rica, Nicaragua, Honduras, Guatemala, Belize, and Mexico.
World map showing submarine cables in 2015. In the 1980s, fiber-optic cables were developed. The first transatlantic telephone cable to use optical fiber was TAT-8, which went into operation in 1988. A fiber-optic cable comprises multiple pairs of fibers. Each pair has one fiber in each direction. TAT-8 had two operational pairs and one backup ...
