Optical Networks

A development of single-mode optical fibers with nearly unlimited bandwidth opens a massive development of long-haul and metropolitan optical networks of the point-to-point type. Using optical cables allows tremendous decreasing of costs to network facilities and maintenance and dramatically increases a quality of services. Many business companies have now an access to services providing through optical fibers. In spite of their advantages, optical cables were not very used in access networks – in a network segment that starts in the central point and finishes at subscribers. Because this segment was usually based on utilizing of metallic homogeneous lines, high-speed services available for residential subscribers and small businesses are limited by possibilities of xDSL and HFC technologies.
