You hear about fiber-optic cables whenever people talk about the telephone system, security system or the high speed networks. Fiber-optic lines are strands of optically pure glass as thin as a human hair that carry digital information over long distances. They are also used in video imaging and building security.
The light in a fiber-optic cable travels through the core (hallway) by constantly bouncing from the cladding (mirror-lined walls), a principle called total internal reflection. Because the cladding does not absorb any light from the core, the light wave can travel great distances.
Fiber optic costs have become much less expensive – Several miles of optical cable can be made cheaper than equivalent lengths of copper wire. Thinner – Optical fibers can be drawn to smaller diameters than copper wire. Higher carrying capacity – Because optical fibers are thinner than copper wires, more fibers can be bundled into a given-diameter cable than copper wires. This allows more phone lines to go over the same cable or more channels to come through the cable into your security camera recorder. Less signal degradation – The loss of signal in optical fiber is less than in copper wire.
Light signals – Unlike electrical signals in copper wires, light signals from one fiber do not interfere with those of other fibers in the same cable. This means clearer phone conversations or TV reception. Low power – Because signals in optical fibers degrade less, lower-power transmitters can be used instead of the high-voltage electrical transmitters needed for copper wires. Again, this saves your provider and you money. Digital signals – Optical fibers are ideally suited for carrying digital information, which is especially useful in computer networks. Non-flammable – Because no electricity is passed through optical fibers, there is no fire hazard. Lightweight – An optical cable weighs less than a comparable copper wire cable. Fiber-optic cables take up less space in the ground
