Development of Optical Fibers, Cables and Optical Systems

Optical communication technology launched in the late 1970s has never stopped due to lack of development. Optical transmission technologies have been evolving consistently beginning from…

Introduction to Plastic Optical Fiber (POF)

Optical fibers are widely used in telecommunication and are now almost replaced the legacy cables in many countries. High-bitrate high capacity transmission offered by optical…

Two Major Prerequisites for Effective Communication

There are two major  prerequisites in order to have a successful communication, let it be between two living things or between two machines. Understandability is…

Add-Drop Multiplexer or ADM

In Fiber optic communication networks Add-Drop multiplexer drops and/or adds one or more optical channels to a signal. This device is an important element of…

Broadband in Telecommunication Technology

The term “Broadband” is ambiguous and is often confused in telecommunication field. Often people use the word broadband without thinking or knowing the real interpretation…

Tensile Strength Test as per International standards

The purpose of tensile strength test is to verify the ability of optical fiber cables to withstand the pulling tension applied during installation and residual…

Macrobending loss in Optical Fibers

The loss induced on the fiber, when it is bend by wrapping on a mandrel is known as Macrobending loss. Macrobending loss happes due to…

What is Absorption?

Light energy is absorbed by ions present in the silica glass. A certain portion of attenuation in optical fiber is caused from the conversion of…

Refractive index and Refractive index profiles of Optical fibers

In simple words to understand, refractive index is the relative speed of light in a medium compared to the speed in vacuum. Thus if a…
