Electromagnetic Waves and their Application in Optical Communication

One of the biggest revolutions in human history was the start of the use of electromagnetic waves for modern communication. Modern communication means the exchange…

Major Components of Fiber Optic System and their Functions

Installation of a fiber optic communication system is complicated and it is not simple as plugging a cord into an outlet. For a professional telecommunication engineer, the installation is not extremely difficult. If the components and their functions are known and identified, then the installation process would be easier. For this purpose, installation staff should know the major system components that are required in all fiber optic communication systems.

Specific Key Performance Parameters of a DWDM System

DWDM (Dense Wavelength Division Multiplexing) has been implemented throughout the world by telecommunication carriers as a measure to cope with the increasing data traffic. Rather…

Chromatic Dispersion in Single mode Fibers

Dispersion limits the transmission distance in optical communications. In simple terms, the broadening of the pulse as it travels along the length of an optical fiber is called dispersion. In fiber-optic measurements, dispersion is often called Chromatic dispersion or short CD. Chromatic Dispersion is variation in the speed of propagation of a light signal with wavelength. Currently installed fiber-optic network spans are limited to around 80 to 100 kilometers that are penalized by dispersion.

Comparison of Two Parallel Technologies in 200G Optical Modules

According to data disclosed by Google, Facebook, etc., the internal traffic of these Internet giant data centers is increasing by nearly 100% every year. Currently,…

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…

Visible Light Communication (VLC) or LiFi

As the terms indicate, Visible Light Communication (VLC) make use of visible light spectrum. VLC is used for data communications and uses visible light in…

Laser Diodes in Fiber Optic Communication

Laser is an abbreviated form of ”Light Amplification by the Stimulated Emission of Radiation”. A laser is a device that produces optical radiation by the…

Maximum Discrete Reflectance Between MPI-S and MPI-R

Optical reflectance is dealt seriously in high bit rate transmission systems. Optical reflectance is defined as the ratio of the reflected optical power present at…
