Optical fiber in computer networks pdf
WebIn case of coaxial cables and twisted cable the maximum signal frequency, and hence the information rate that can be transmitted using a solid conductor is limited. Optical fiber differs from both these transmission media in that it carries the transmitted information in the' form of a fluctuating beam of light in a glass fiber rather than as an electrical signal … WebFiber-Optic Cables An optical fiber consists of a core (denser material) and a cladding (less dense material) Simplest one is a multimode step-index optical fiber Multimode = multiple paths, whereas step-index = refractive index follows a step-function profile (i.e. an abrupt change of refractive index between the core and the cladding)

Difficult to install and expensive when compared with twisted pair. If the shield is imperfect, it can lead to grounded loop. Fiber Optic Cable These are similar to coaxial cable. It uses electric signals to transmit data. At the centre is the glass core through which light propagates.
