Optical Power meter OPM

Optical Power Light energy per unit time. A power is measured in watts = joules / second. In optical communications, powers is calculated dBm. Optical powers are measured with optical power meters.Optical power meter and Optical time domain reflectometers (OTDRs)…
Electromagnetic waves

Wave A wave is a disturbance that transfer energy from one place to another. It does not transfer matter during the energy transfer. Electromagnetic wave Electromagnetic waves are created by accelerating charges.EM waves are composed of oscillating magnetic and electric…
How mobile phone works

Mobile Phone A mobile phone is a device used to make and receive calls over a radio frequency carrier (Electromagnetic waves) while the user is moving within a telephone service area. Mobile phones use a cellular network architecture therefore they…
Antenna

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,…
Total Internal Reflection

Total Internal Reflection It is the complete reflection of light ray inside an optically denser medium. Critical Angle The angle of incidence in an optically denser medium for which the angle of refraction is 90 degree.
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.…
