Coaxial cable uses a shield to protect a copper wire carrying a signal via an electric current. The shield reduces noise on the line. Fiber optics use glass fibers carrying a signal via electromagnetic waves (i.e. light).
guided media is that media which use some physical path like coaxial cable fiber optics etc
Many companies are using fiber optics for backbone connection.
Fiber and fibre mean the same thing. The only difference is that fiber is derived from American English, and fibre is derived from European English.
Hi, Fiber Optics transmit signal using lights rather than electic current, so when signal passes though an optical fiber cable, it does not generate electric or magnetic field around it, and it is not affected by surrounding magnetic or electric fields Adv of optical fiber is that they are immune to noise, signal passes at lights speed, and no signal power is lost along the transmission line.
No, optical fiber cable has not completely replaced coaxial cable. While fiber optics offer advantages such as higher bandwidth, longer transmission distances, and immunity to electromagnetic interference, coaxial cable remains in use for various applications, particularly in legacy systems and certain broadcasting scenarios. Many networks utilize a combination of both technologies, leveraging the strengths of each where appropriate.
