dwdm system

DWDM device is connected to the optical fiber automatic switch protection system, manual core scheduling is not required during cutover. You only need to perform simple switching on the network management system. During core-core scheduling, the most common problem is that the return loss value is too low, which is sometimes troublesome to handle. The most basic

Wavelength Division MultipLexing Dense Wave Division MultipLexing, DWDM) injects new energy into the fiber network and provides amazing bandwidth in the laying of new fiber trunk networks by telecom companies. DWDM technology utilizes Optical Fiber capabilities and advanced optical transmission equipment. The name of wavelength division multiplexing is obtained by transmitting multiple wavelengths of optic

Q1,design an account SystemThe simplest is to find an example, such as the user system of Twitter.Consider what needs to be: 1,register/updata/remove.2,login/logout.3, balance/menbership.Consider what is most important in the requirements, what is most frequent: login/logout most frequent, but login than the Logout frequency should be much larger, so consider login to be able, in addition register is also very important, also need to design first alon

The coordinate system of cocos2d-x is very important, it is very important to understand the engine well. Note written very clearly, control the results of the operation to see the code bar! BOOL Helloworld::init () {bool BRet = false; do {cc_break_if (! Cclayer::init ()); OpenGL has the same coordinate system as the world coordinate system, in the low

(1) Windows coordinate systemThe Windows coordinate system is divided into logical and device coordinate systems, both of which are supported by GDI. In general, GDI's text and graphics output functions use logical coordinates, while the mouse position in the client area is moved or the mouse is pressed with device coordinates.The Equipment Coordinate system is divided into screen coordinate

High-density and highly integrated OTN Wavelength-Division transmission SystemThis wave division multiplexing technology in the heyday, a variety of new technologies emerge. The goal is the same, that is to meet the network era of the operators. Long long ago, can only use CWDM coarse wave points, channel number is not enough to say, transmission distance is also very limited, line and equipment attenuation calculation,10G no relay transmission Kilometer is already a bottleneck. This technical

Job:1. Write and debug routine subroutines that can realize various functions.2, write and debug the visit to the pipeline interrupt processing program.3, constructs the routine subroutine entry Address table.In the user program, a system call is scheduled where the operating system service needs to be requested. In this way, when the program executes to this command, there will be an interruption, the

interoperability. In short, where fiber resources are scarce, where can be used WDM transmission system, not only to solve the problem of resource shortages, but also can greatly solve the rental of optical fiber or laying optical cable more cost savings. Next, I will give you a few very typical WDM transmission system application scenarios. 650) this.width=650; "src=" Http://s3.51cto.com/wyfs02/M01/6E/FE/

Fiber-optic communication is favored because of its advantages such as large capacity, high transmission information quality, long transmission distance, stable performance, anti-electromagnetic interference, and strong corrosion resistance. Especially in the last decade, with the increasing demand for broadband services, optical fiber communication has been vigorously developed. At present, the total length of optical fiber cables in China's communications industry has reached more than 2 milli
