↬ Some advantages of using an optical fiber are as follows :

1) LOW POWER LOSS : In comparison to copper, an optical fiber offers low power loss. Hence,using optical fiber allows for longer transmission distances.

2) WEIGHT AND SIZE : Optical fiber cables are much light-weighted and thinner than metal wires which makes fiber easier to install.

3) SPEED : Faster speed is an important advantage using optical fibers. An optical fiber suppors high speed in order to transmit more information per unit of optical fiber.

4) SECURITY : As the optical fibers do not radiate electromagnetic energy, emissions cannot be intercepted. Optical fibers are also difficult to tap.

5) FLEXIBLE : Optical fibers are flexible. It has greater tensile strength than other fibers of the same diameter.

6) LIFESPAN : In comparison to copper or other types of cables, an optical fiber usually has a longer life cycle.

➤ WHAT IS AN OPTICAL FIBER ?

↠ An optical fiber, also known as Fiber optic cable is a transparent and flexible fiber made by drawing glasses. It uses pulses of light travel,ing through an optical fiber to transmit data.

➤ TYPES OF OPTICAL FIBER :

↠ Generally, there are three types of fiber optic cables. These are :

(i) Two glass optical fiber,

(ii) Single mode fiber optic cable,

(iii) Multimode optical fiber.

➤ USES OF OPTICAL FIBER :

↠ An optical fiber is used in various fields. Some uses of optical fiber are mentioned below : -

➲ In communication system, optical fiber cables are used for transmitting and receiving purposes.

➲ Optical Fibres are used for Broadcasting to transmit high definition television signals which have greater bandwidth and speed.

➲ Optical fibres are used in Defense purpose for data transmission in high-level data security fields of military and aerospace applications.

➲ Optical fiber cables are used for networking between computers in a single building or across nearby structures to make it easier and faster.

➲ Optical fibers are used in lighting and decoration as these cables provide an easy, economical and attractive solution to lighting projects.
