Fiber optics -- the choice for minimum communications downtime
Fiber optic cable carries serial data reliably up to 4 km
(2.5 miles), much further than conventional copper lines.
Fiber optic data transmission uses light in glass fiber
cable as a communication medium. It is ideal for spanning
areas with severe interference, such as near heavy electrical
equipment, welding or radio transmissions. Being nonelectric,
fiber optic cable will not pick up any noise.
Power surges and spikes are created by electrical
equipment, by nearby lightning strikes and from other
sources. They are picked up by copper data lines and
transmitted to the connected devices, garbling messages
and damaging equipment. Fiber optic cables do not
transmit power spikes or surges, providing the most
reliable system possible.
Ground loops interfere with data communications through
copper. Using fiber optics eliminates ground loops by not
providing a conductive path for the ground.
