-speed single channel transmission, can realize the ultra-large capacity of the transmission system. Excellent solution to the problem of insufficient capacity.2. Ultra Long Distance wavelength division transmission System There is a problem that needs to be solved, that is, in the transmission to a certain distance after the light power will become smaller, then how to solve this problem? We can design the scheme--the EDFA erbium-doped fiber amplifier is configured in the relay room throughout

Introduction to Lead/lag compensatorfirst, what's the difference between a compensator and a controller? There is no definite boundary, the two are similar. There's no need to tangle with this conceptI've been looking for some ideas on this subject, and there's a very "popular" commentary .Lutz von Wangenheim· Hochschule BremenHere is a excerpt from "G. Ellis, Control System Design Guide":"Compensators is specialized filters ... designed to provide a

alternative method is Babinet-Soleil compensator, which can convert any input polarization state to any desired output polarization state. The core device of this device is a composite wave chip 2a consisting of two wedge-shaped double-state crystals ). The variation of wave thickness corresponds to the total delay) can be achieved through the relative slide of the two crystals. At the same time, the orientation of the composite wave can be rotated a

will save more time and will not burden another existing method. Principle 4: Stress In works of art, emphasis is placed on the use of comparison to make one aspect of the work stand out and form a focus. In many APIs, the focus may be the anchor of the main method of a channel or class library. For another emphasis example, you can refer to the "link" method or fluent API. it highlights the center object of the class library by adding emphasis. Jquery tends to emphasize this object from many f

At the same time, the dispersion value remains non-zero, and the minimum value with a Code such as 2 ps/nm. above), it is sufficient to suppress non-linear effects such as four-wave mixing and cross-phase modulation. It is suitable to activate a DWDM System with sufficient wavelengths and meet the development needs of both TDM and DWDM. To achieve th

Includes the CRM worker (is the main part of CRM, the interface provided through the CRM infrastructure conceal The relevant information is written to the log, and the log file is retrieved when required, and the CRM compensator (used in the transaction When completed, the transaction and generated log files are submitted to the user performing the transaction. 11, Concurrency: That is, allow

To be blunt is to break the idea of a failure on a transaction, and to specify that it

it can use the powerful Electronic Dispersion Compensation (EDC) capability to clear signal distortion at a very low cost. Therefore, through the use of 100 Gbit/s PM-QPSK and EDC, coherent detection technology can be improved by 6 dB (compared with the direct detection of OOK); the use of high encoding gain FEC can be improved by 2 to 3 dB; because the transmission cost of CD and PMD is reduced, 1-2 dB is improved. In this way, the total improvement can reach 9-11 dB, making the 100 Gbit/s PM-
