What Is a Fiber Optic Cable?

Answer: The fiber optic cable in telecommunication is the technique that is used for the information transmission in the form of light waves through the plastic or glass fiber.

The fiber optic cable consists of the glass that is contained inside the plastic casing. For the larger geographic area and the high performance, the fiber optic cable is best to use, because related to the cable wires its bandwidth is greater and transfers data over a large distance. Most of the TV cable internet and the landlines are connected with the help of fiber optic cable. The signal is transmitted through it in light form and the light-emitting diodes are the ones that generate the signals.

Fiber optic contains more than one glass strand and they are thicker than a human hair. The core is the center of the cable that gives the path for the light signals. And the cladding is the layer that covers the core so that the signals won’t be lost and reflet within the glass and also help the signals to pass through the bends. The fiber optic cable has two modes one is single-mode and another one is multimode. the single-mode glass is this and the laser is used to generate the signals while the multimode uses the LED (light-emitting diode) and the glass is thick relative to the single-mode.

Some of the advantages of the fiber optic cable are listed in the following:

• The fiber optics have a high capacity, and the fiber optic bandwidth it contains is easy to carry having the same thickness as the copper cable. The standard for fiber optics is 10 Gbps,40 Gbps, and 100 Gbps.
• As the light travels the large areas without any signal loss and strength in the fiber optic, the signal booster is not much required.
• The interference has not much effect on fiber optics, the copper cable needs a shield against the electromagnetic interference. The shield is also somehow but not very effective, the fiber optic does not have many problems.
