Optical fibre cable :- Optical fibre cable consists of a central glass core , surrounded by several layers of protective materials . It transmits light instead of electronic signals , does eliminating the problem of electrical interface . Optical fibre cable has the ability to transmit signals over much longer distances then covered by coaxial and twisted pair . Twisted pair :- twisted pair cables were invented by Alexander Graham Bell in 1881 . The twisted pair cable is the most widely used medium for telecommunication and consists of copper cable that are twisted into pairs .
