Over the past decade, optical communications has penetrated deep into the telecommunications systems of most developed countries. Optical fiber has replaced copper to a large extent in the trunk network, bringing with it the benefits of increase regenerator spacings, lower cost, and improved reliability through the reduction in the amount of electronics. The use of optical communication technology has enabled much greater transmission speeds, with the result that 2.5 Gbit/s will become a standard transmission rate within the next few years.
