SCM system in the development process, RAM is a more commonly used devices, in power in the domain of information processing, RAM memory and a buffer role. In light of the rapid development of communications today, with a similar field programmable logic devices, optical RAM memory - optical delay line OFDL (Optical Fiber Delay Line) a fixed length of optical fiber, optical signal will enter the delay A fixed time out from the other end, the optical signal can be realized and the buffer storage. It is passive components, relatively stable. OFDL optical delay line in the full sense of achieving all-optical communications, optical memory to achieve the principle of the use of optical signals in optical fiber transmission delay of the optical signal to achieve the purpose of storage.
In practice, often flexible adjustments according to the requirements of the optical signal delay, the design can be introduced is a delay in certain areas, arbitrary manually adjust the optical delay line device, that is, through a flexible programming Optical delay line conditioning system. Programmable optical delay line system in the small hours, frequency division and ATM (asynchronous transfer mode) switching system-wide application in modern radar, optical switching technology, electronic warfare equipment, all kinds of rapid information processing systems, have both A good prospect.
Programmable optical delay line system, as the name suggests, its function is to be able to control to achieve through programming to meet different requirements of the optical signal delay. The design of the optical delay line is a computer system, SCM optical delay line, and optical switch matrix of three parts consisting of, among computer and microcontroller through the serial line connectivity, delay control of a computer and coordination of SCM Completed, supplemented by a programmable logic device control signals, a real sense of the importation of adjustable.
Let you see....
maybe it has some wrong in it...
i'm sorry....
In the monolithic integrated circuit system performance history, RAM is one kind of commonly used component, in the electricity territory information processing, RAM plays the memory and the cushion role.In optical communication rapid development today, one kind similar and in the programmable logical component electricity territory RAM optical memory - - optical fiber delay line OFDL (Optical Fiber Delay Line) uses the fixed length optical fiber, will enter light signal time delay fixed time will send out from another end, might realize the light signal cushion and the memory.It is the passive component, quite stable.Optical fiber delay line OFDL realizes the entire optical communication in the complete significance, realizes the optical memory principle is uses the light signal to achieve the memory light signal in optical fiber transmission time delay characteristic the goal. In the practical application, must adjust the light signal nimbly frequently according to the request the time delay, this design introduction is one kind may in certain time delay scope, manual adjusts willfully the optical fiber delay line component, namely one kind may through the programming nimble adjustment optical fiber delay line system.The programmable optical fiber delay line system in the time-sharing, the frequency division and ATM (asynchronous mode of transmission) in the light exchange system applies widely, in the Modern Radar, the light exchange technology, the electronic warfare equipment, in each kind of fast information management system, has the good application prospect. The programmable optical fiber delay line system, as the name suggests, its function is must be able to realize through the programming control satisfies the different request the light signal time delay.This design optical fiber delay line system has the computer, the monolithic integrated circuit as well as the optical fiber delay line light switch matrix three parts of constitutions, between the computer and the monolithic integrated circuit through the serial port line connection, the timing control has the computer and the monolithic integrated circuit coordination completes, auxiliary produces the control signal by the programmable logical component, realization in the true sense input adjustable.
