An optical fiber cable (or fiber-optic cable) is a more or less flexible cable which contains one or several (sometimes even many hundreds of) optical fibers. Due to protective layers (made of polymers and sometimes also metals) which prevent excessive bending as well as damage due to externally applied stress, fiber cables can be much more robust than bare fibers. Also, fiber cables protect glass fibers against moisture.
A variety of constructions are used for fiber cables:
