Analysis of WMD by learning Huawei OptiX OSN 8800Luis
OptiX OSN 8800 is mainly used in national trunk lines, regional/provincial trunk lines, and metropolitan area networks. It features large-capacity OTN dispatching capabilities and integrates ROADM (dynamic optical add/drop multiplexing), Tbit electrical crossover, and 100M to 100G full-grain Dispatching, photoelectric intelligent ASON, 40G/100G transmission, rich management and protection, and other functions can build end-to-end OTN/WDM backbone transmission solutions for operators to realize large-capacity dispatch and ultra-wideband intelligent transmission.
OptiX OSN 8800 T64/T32/T16 can form a complete OTN end-to-end network, can also build a WDM network with OptiX BWS 1600G, OptiX OSN 1800, OptiX OSN 9800, and can also be used with NG-SDH, PTN, or data communication equipment Hybrid networking realizes a complete transmission solution.
What is WDM？
WDM is the abbreviation of wavelength division multiplexing technology.
Speed of light in the air: 30km per second
Speed of light in fiber: 20km per second
WDM realizes high-speed transmission. Similar to a prism, white light can be divided into seven-color light. The seven-color light converges into white light at the receiving end. Each color light can be further subdivided and identified by wavelength.
80-wave WDM system, theoretically the rate is increased by 80 times.
WDM can realize low-cost and ultra-long-distance transmission. Ordinary communication technologies, such as routers/switches/SDH, need to change vehicles <80km-100km> after transmission for a certain distance to continue running, which is costly. WDM can refuel all cars at the same time over a certain distance without changing cars. It can run several thousand kilometers in a single run, which greatly reduces the cost.
Gray light generally occupies an optical fiber, the center wavelength is 850nm, 1310nm, or 1550nm
Color light: the light of a specific wavelength is called color light, whether it is DWDM or CWDM
C/L band loss is the smallest, and the most widely used band in the current WDM system is the C band
