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…
5G Technology 5G is the fifth generation of wireless network technology. 5G is the next generation of wireless technology, designed to fulfill the User demand of increased bandwidth. Future technologies such as IoT, high-quality video streaming and virtual reality require…
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)…
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…
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…
Protocol It is a language to transfer information between two or more people / devices. A protocol is a set of mutually accepted rules that governs the communications between computers on a network. A protocol defines What is communicated How…
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.
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 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.…
