Large selection of fiber optic cables in high quality at good prices. Fiber optic cables can transmit data quickly over long distances and with more bandwidth than other cables. Optical fiber cables are made of very thin glass fibers that send signals using light. Since nothing is faster than light, that's as fast as anything can be sent. To use fiber optic cables, active equipment is required that sends and receives the light signals. These can contain large amounts of data/information.
