• Applications of optical fiber communications include telecommunications, data communications, video control and protection switching, sensors and power

1.  Telephone networks


  • Optical waveguide has low attenuation, high transmission bandwidth compated to copper lines, therefore numbers of long haul co-axial trunks l;links between telephone exchanges are being replaced by optical fiber links.

2.  Urban broadband service networks


  • Optical waveguide provides much larger bandwidth than co-axial calbe, also the number of repeaters required is reduced considerably.





  • Modern suburban communications involves videotext, videoconferencing videotelephony, switched broadband communication network. All these can be supplied over a single fiber optic link. Fiber optic calbes is the solution to many of today’s high speed, high bandwidth data communication problems and will continue to play a large role in future telecom and data-com networks.
