1. Purpose andsignificance (including domestic and foreign research status analysis)

The growing trend in communications has ledto the development of technology to keep up with this growing need. Processordevelopment, faster and faster online games, more and more complex applicationsand computer services, the growth of the Internet is a number of factors thathave generated the need for a network that provides greater bandwidth for usersat the access level, Inter-network optical switching is critical because theconversion of light to electronic signals is a critical bottleneck in completeoptical networks because of the need to exchange large amounts of informationthrough several nodes. Therefore, optical switching is a key element of apromising development and dynamic reconfigurable optical network. The largeload capacity of the fiber optic connection is limited by the electronicprocessing, which is less than the speed of transmission through the fiberoptic cable. For its processing, the optical signal must first be transferredto the electronic domain to be controlled, managed (extracted: origin,destination, quality of service, etc.) and transmitted over the network. Thisprocess increases the delay of communication and wastes Providing a largebandwidth of optical media, so since a few years ago, all-optical networkresearch and development has been an interesting area in the field of opticalcommunications, has been made for these urgent needs for lightning light Switchtechnology.

2. 研究的基本内容与方案

2. the research(design) the basic content, objectives, to be used in technical solutions andmeasures

fundamental contents:

optical switchingtechnology is not through any optical / electrical conversion, in the opticalfield directly to the input optical signal exchange to a different output.optical switching technology can be divided into optical path optical switchingtype and packet optical switching type, the former can use oadm, oxc and otherequipment to achieve, while the latter part of the performance requirements ofoptical components. as the current optical logic device function is alsorelatively simple, can not complete the control part of the complex logicprocessing functions, so the existing international group of optical switchingunit also by the electrical signal to control, the so-called electronic controloptical exchange. with the development of optical device technology, theultimate development trend of optical switching technology will be lightcontrol optical exchange.
