Does Fiber Optics That ?

Does Fiber Optics That ?, Fiber optic cables are composed of a thin optical glass as thick as a human hair that carry digital information in a very far distance. Also used in the medical-imaging, inspection and mechanical engineering.

Fiber optics (optical fibers), a thin glass layer as thick as the diameter of human hair. In a collection called optical cables and used to send signals over long distances

If we observe closely an optical fiber, we will see the following sections:

* Core - Glass thin, the center of the fiber where the light will pass

* Cladding - Outer optical material surrounding the core that reflects light back into the core

* Buffer coating - Plastic coating that protects the fiber from damage and moisture

Hundreds or thousands of optical fibers can be arranged in the collection of optical cable. Collection is protected by a cable from the outer covering, called a jacket.

Fiber optics comes in two types:

* Single-mode fiber

* Multi-mode fiber

Single mode fibers have small cores (about 3.5 x 10-4 inches or 9 microns in diameter) and transmit infrared laser light (wavelength = 1300 to 1550 nanometers). Multi-mode fibers have larger cores (about 2.5 x 10-3 inches or 62.5 microns in diameter) and transmit infrared light (wavelength = 850-1300 nm) of the LED lights.

Some optical fibers can be made from plastic. These fibers have a large core (0.04 inches or 1 mm in diameter) and transmit visible red light (wavelength = 650 nm) from LEDs
