Fiber optic cable is a type of high-speed data transmission medium. It has tiny glass or plastic filaments that carry light beams.
Digital data is transmitted by cable via rapid pulses of light. A fiber optic transmits receiving end translations of light pulses into binary values, which can be easily read by a computer.
Since optical fiber cables transmit data via light waves, so they transfer information to the speed of light. It is not surprising that fiber optic cables provide the fastest data transfer rates in any data transmission medium. Not only this, they are much less susceptible to noise and interference when compared to copper wires or telephone lines.
Fiber optic cables are much more fragile (lighter or easier to break) than other metallic counterparts and therefore they also need more protective shielding.
Where copper wires can be easily splice and mend (connected) when needed, broken fiber optic cables often have to be replaced.
For example, most transatlantic telecommunications cables used between the US and Europe are fiber optic.
In the last few years, fiber optic technology has also become very popular in local Internet connections.
For example, some ISPs are now offering “fiber Internet,” which provides Internet access via a fiber optic line. Fiber connections can provide data transfer speeds of up to 1 Gbps to your homes and businesses .
