Dispersion also referred as pulse spreading, it signifies the spreading out of pulses of light waves when it is propagated through the optical fiber. It occurs mainly because of the difference in time taken by the propagation of optical rays in different paths within the fiber core. The different dispersion mechanisms include: In other words, … Read more

In the fast-paced digital age, the television industry has undergone a transformative revolution, offering consumers a wide range of options that promise to redefine their entertainment experience. Digital TV refers to the migration from analog to digital broadcasting, offering improved image and sound quality, enhanced reception, and the potential for additional channels. A Smart TV … Read more

Television (the electronic delivery of moving images and sound from a source to a receiver), is currently delivered in a variety of ways: “over the air” by terrestrial radio waves (traditional broadcast TV); along coaxial cables (cable TV); reflected off of satellites held in geostationary Earth orbit (direct broadcast satellite, or DBS, TV); streamed through the Internet; and … Read more

Remote Authentication Dial-In User Service (RADIUS) RADIUS is a networking protocol that provides centralized authentication, authorization, and accounting (AAA) services primarily for remote access. It allows a network access server (NAS) to communicate with a central server to authenticate users and authorize their access to network resources. It’s commonly used for dial-up, VPN, and wireless … Read more

What is Patch cable? A patch cable, also known as a patch cord or patch lead, is a type of Ethernet cable used to connect devices within a local area network (LAN) or to connect network equipment to a data outlet. Patch cables are commonly used to establish temporary or permanent connections between devices such … Read more

Power over Ethernet (PoE) switches are network switches that provide power to connected devices over Ethernet cables, eliminating the need for separate power sources. There are several standards for PoE, including PoE, PoE+, and PoE++, each offering different levels of power delivery and compatibility. Let’s talk about them. PoE (Power over Ethernet) PoE, based on … Read more

Fiber optics refers to the technology of transmitting light down thin strands of highly transparent material, usually glass but sometimes plastic. An optical fiber is a long thin strand of glass. A fiber-optic cable is made up of incredibly thin strands of glass known as optical fibers; one cable can have as few as two strands … Read more

What is a Geostationary Satellite? A Geostationary Satellite, also known as a Geosynchronous Equatorial Orbit (GEO) satellite, is a type of artificial satellite that orbits the Earth at an altitude of approximately 35,786 kilometers (22,236 miles) above the equator. This specific altitude allows the satellite to match the Earth’s rotation period, resulting in the satellite … Read more

Forward Error Correction (FEC) FEC is a technique used to detect and correct errors in transmitted data without the need for retransmission. FEC involves adding redundant information (parity bits or error-correcting codes) to the transmitted data. This redundant information allows the receiver to detect and correct errors without requiring the sender to resend the data. … Read more

Electromagnetic interference (EMI) refers to the disturbance caused by electromagnetic radiation on electronic devices, equipment, or systems. This interference can disrupt the proper functioning of electronic devices and cause issues such as signal distortion, data corruption, increased error rates or even complete failure. EMI can occur through mechanisms such as radiation from electronic devices, power … Read more
