- 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.
