The futFor fiber optic communication, ultra-high speed, ultra-large capacity and ultra-long distance transmission have been pursued since the standard, and all-optical network is also the dream of people relentlessly pursued. So we should strive to develop like the following aspects:
① to the development of ultra-high speed system.
②The evolution of WDM system to very large capacity.
③Developing new generation of optical fiber
④All-optical network.
The future high-speed communication network will be an all-optical network. All-optical network is the highest stage of fiber optic communication technology development and also the ideal stage. At present, the development of all-optical network is in the early stage, but it has shown a good prospect of development. From the development trend, the formation of a real, WDM technology and optical switching technology-based optical network layer, the establishment of a pure all-optical network, the elimination of electrical and optical bottlenecks has become the inevitable trend of the future development of optical communications, but also the core of the future information network, but also the highest level of development of communications technology, but also the ideal level.
