Applications of Optical Fiber Communications

. Applications of optical fiber communications include telecommunications, data communication video control and protection switching, sensors and power applications.
1. Telephone networks
. Optical waveguide has low attenuation, high transmission bandwidth compared to copper lines, therefore numbers of long haul co-axial trunks 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 cable, 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 cable 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.
