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…

Four-Wave Mixing

Four-Wave Mixing is one of the four Non-linear attributes in optical fiber communication. As the name indicates, the fourth wave gets generated when three (or…

Maximum Differential Group Delay

In fiber optics, the differential group delay, which is often shorted as DGD is the time difference between the fractions of a pulse that are…

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…

What are the Factors that affect Polarization Mode Dispersion?

Polarization Mode Dispersion or PMD is the broadening of pulse due to the difference in velocities of two orthogonally polarized optical signals. Difference in speed…

What is Polarization Mode Dispersion?

Polarization mode dispersion, abbreviated as PMD is the broadening of pulse due to the difference in velocities of two orthogonally polarized light signals. In an…
