https://mocomi.com/ presents: What is Fiber Optics?

Fiber optics or Optical Fibers are very thin and flexible strands of glass which are used today to transmit data over long distances with minimum loss.

Watch this interesting video explaining what is fiber optics, how it works, uses and conclusion with the help of this animated learning module for kids.

An optical fiber is a semi-flexible, transparent, and extremely thin strand of pure glass that has the diameter of a human hair. Thousands of these strands are arranged in bundles to make a thicker cable. Since glass is optically transparent we are able to send information-laden rays of light over long distances.

A fiber optic cable is made up of five parts:

Strands of glass that are bundled together to make one single channel of light called makes up the core. The diameter of the core dictates how much information can be sent and received at once.

A protective sheath or coating around any structure or material is known as the cladding. In fiber optic cables the silica cladding increases the total internal reflection of the core. Therefore a light pulse can pass through the entire length of the fiber with little data loss.

A layer of plastic surrounds the core and cladding to reinforce the fiber core. The coating provides extra protection and prevents the cable from bending too much.

The strengthening fibers around the coating give added support to the coating especially when it comes to stretching tension.

Finally all this is covered in the cable jacket like any other cable or wire.

The only part of a fiber optic cable that carries data is the tiny core in the center but it has layer upon layer of protection because glass is extremely brittle and in order for it to function at its best, there can be no breaks in the fiber at all. Add to that the high cost of producing them and you will know why every precaution must be taken to prevent damage.
