Advantages of Fiber Optics


11/33

Advantages of Fiber OpticsThinner- Optical fibers can be drawn to smaller diameters than copper wire.

Higher carrying capacity - Because optical fibers are thinner than copperwires, 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 tocome through the cable into your cable TV box.

Less signal degradation - The loss of signal in optical fiber is less than incopper wire.

Light signals - Unlike electrical signals in copper wires, light signals from onefiber do not interfere with those of other fibers in the same cable. This meansclearer phone conversations or TV reception.

Low power- Because signals in optical fibers degrade less, lower-powertransmitters can be used instead of the high-voltage electrical transmittersneeded 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 wirecable. Fiber-optic cables take up less space in the ground.
