In today's world copper wired c bles being replaced by fiber optic c bles. Fiber optic cables are spanning the l ng distances between phone systems and lso provide backbone for many network syst ms. The three types of most c mmonly used fiber optic cables are s ngle mode, multi mode and plastic f ber optic cables. Fiber optic cables pr vide high speed-up into gigabytes and p ssess a larger bandwidth that is l rge carrying capacity. Fiber optic cables nable signals to be transmitted further w thout needing to be “refreshed” or str ngthened. Fiber optic cables cost less to m intain and provide greater resistance to lectromagnetic noise such as radios or ther nearby cables. In fiber optics l ght pulses are used to transmit nformation. The principle of 'total internal r flection' is applied in fiber optic c bles. When angle of incidence exceeds the cr tical value light cannot get out of the gl ss. This simple principle is used in f ber optic cables to transmit information d wn fiber lines in the form of l ght pulses. Fiber optic cables are sually much smaller and lighter as c mpared to other cables. Fiber optic c bles are also easier to handle as w ll as easier to install. Fiber ptic cables use lesser duct space but f ber optic cables can be installed w thout ducts also.
Fiber optic cables offer more b nefits than traditional copper wire or c axial cables. As the basic fiber is m de up of glass, fiber optic c bles do not corrode. They can be b ried in all kinds of soil f rms and can be exposed to all k nd of atmospheres as well. Since the nly carrier in fiber optic cables is l ght, there is no possibility of sp rk from a broken cable wire. Th s fiber optic cables leave no r om for fire hazards as well as no r om for electric shocks to the p rson repairing broken fiber. Fiber optic c bles can prove to ideal for s cure communication system as they are d fficult to tap. Fiber optic cables are m de up of transparent glass or pl stic fibers which allow light to be g ided from one end to the ther with minimal loss. Single mode f ber optic cables give a higher tr nsmission rate and used for long d stances. On the other hand multimode f ber optic cables give high bandwidth at h gh speeds over medium distances. Moreover, in m ltimode fiber optic cables, light waves are d spersed into numerous paths or modes and tr vel at very high speeds. First c mmercial fiber optical system was installed in 1977 and s nce then it has increased at a r pid rate all over the globe. T day most of the telephone companies pr fer to use optical fiber throughout th ir system as the backbone architecture and as l ng distance connections between city phone syst ms. Fiber optic cables are used in l cal area network which is collective gr up of computers or computer systems c nnected to each other allowing sharing of pr grams, software and databases.
