Fiber optics are very thin strands of glass, about the diameter of a human hair, that transmit light and are used in telecommunications and medical imaging. There are two types of optical fibers: single-mode and multi-mode. Fiber optics work by transmitting light through the fiber using total internal reflection, similar to how a mirror can reflect light around a corner. Fiber optic systems consist of a transmitter that converts electrical signals to light, the optical fiber that carries the light, optical repeaters that boost the signal, and a receiver that converts the light back to an electrical signal.

1. How Fiber Optics Work
Fiber Optics are used about the telephone
system, the cable TV system or the Internet.
Also they are used in medical imaging and
mechanical engineering inspection etc.

2. Introduction of Fiber Optics
Fiber Optics are strands that long and thin glass
about the diameter of a human hair.
Optical fibers have two types:
Single-mode fibers and Multi-mode fibers.

3. The roll of Optical Fiber Transmit
Light
Optical Fiber Transmit Light like of a beam can go
straight in the hallway. If the hallway has a bend
in it, it could place a mirror at the bend to reflect
the light beam around the corner.

4. Relay System of Fiber Optic
Fiber Optic consist of many relay systems:
Transmitter, Optical fiber, Optical regenerator and
Optical receiver. These are important for Fiber
Optic component.

5. Fiber Optics advantages
● Thinner – optical cable can be made smaller
than copper wire.
● Less expensive- optical cable can be made
cheaper than equivalent lengths of copper wire.
● Other advantages are as follows.
● Higher carrying capacity
● Less signal degradation
● Low power
● etc....

6. How to make Optic Fiber
● The following step that is indispensable when
making optical fibers.
● 1 The cylinder of the glass of preform is made.
● 2 An optical fiber is drawn from a preform.
● 3 The test of a fiber.
● Things of the above is realized by many
technology and machines.
