Optical power budget and Link loss

Link power budget Amount of light required to transmit signals successfully through a fiber cable from source to destination. Link power budget calculation is used to ensure that power reach at the receiver end is greater than average power required…
Optical fiber Losses

We have already discussed Optical fiber, Power meter and OTDR in our previous videos. Today we will focus on fiber losses only. Fiber Optic Comm  Fiber optic cable is lighter, smaller and flexible than copper cable. It can transmit optical…

What is Antenna An antenna is a metallic conductor system capable of radiating and capturing electromagnetic energy. It converts electrical energy into electromagnetic energy & electromagnetic energy into electrical energy.
What is Data Center

Data Center A data center consists of hardware such as server racks and power distribution units, software such as server operating systems and network monitoring tools. A data center is a facility that centralizes an organization’s IT operations and equipment,…
Refraction of Light

Refraction of Light Bending of light when it enters from one optical medium to another is called refraction of light. Light travels with different speeds in different transparent medium.Its speed in air is 3×108 m/s  and 2×108 m/s in glass.…
Reflection of Light

Reflection of Light After striking with a surface, Return of light, Sound, Wave or any body is called reflection. Light rays travel in straight line.In physics, we use straight lines with arrows to represent paths of light.The arrows represent the…
Satellite Communication

Satellite Satellite is an object that orbits or rotate around another object in a particular path Orbit. Our solar system is a good example. How satellite stable in orbit? A satellite remains in orbit because the centrifugal force caused by…
Infrared IR

Discovery of Infrared In 1800, William Herschel conducted an experiment measuring the difference in temperature between the colors in the visible spectrum. Infrared is a section of invisible light on the electromagnetic spectrum. It’s a form of radiant heat that can…
ISM Frequency Band

ISM Frequency Band The ITU (International Telecommunication Union) had originally reserved a portion of the RF spectrum globally for industrial, scientific and medical applications. Such as process heating, microwave oven, and medical diathermy equipment etc. The main feature of the…
