【正文】 纖的非線性效應(yīng)，讓脈波能夠抵抗色散而維持原本的波形。1990年至2000年間，光纖通信產(chǎn)業(yè)受到互聯(lián)網(wǎng)泡沫的影響而大幅成長。此外一些新興的網(wǎng)絡(luò)應(yīng)用，如隨選視頻（video on demand）使得互聯(lián)網(wǎng)帶寬的成長甚至超過摩爾定律（Moore’s Law）所預(yù)期集成電路芯片中晶體管增加的速率。而自互聯(lián)網(wǎng)泡沫破滅至2006年為止，光纖通信產(chǎn)業(yè)通過企業(yè)整并壯大規(guī)模，以及委外生產(chǎn)的方式降低成本來延續(xù)生命?，F(xiàn)在的發(fā)展前沿就是全光網(wǎng)絡(luò)了，使光通信完全的代替電信號通訊系統(tǒng)，當然，這還有很長的路要走。fiberoptic municationsOptical fiber is used by many telemunications panies to transmit telephone signals, Internet munication, and cable television to much lower attenuation and interference, optical fiber has large advantages over existing copper wire in longdistance and highdemand , infrastructure development within cities was relatively difficult and timeconsuming, and fiberoptic systems were plex and expensive to install and to these difficulties, fiberoptic munication systems have primarily been installed in longdistance applications, where they can be used to their full transmission capacity, offsetting the increased 2000, the prices for fiberoptic munications have dropped price for rolling out fiber to the home has currently bee more costeffective than that of rolling out a copper based have dropped to $850 per subscriber in the US and lower in countries like The Netherlands, where digging costs are 1990, when opticalamplification systems became mercially available, the telemunications industry has laid a vast network of intercity and transoceanic fiber munication 2002, an intercontinental network of 250,000 km of submarine munications cablewith a capacity of Tb/s was pleted, and although specific network capacities are privileged information, telemunications investment reports indicate that network capacity has increased dramatically since In 1966 Charles and George hockom proposed optical fibers at STC Laboratories(STL)at Harlow, England, when they showed that the losses of 1000 dB/km in existing glass(pared to 510 db/km in coaxial cable)was due to contaminants, which could potentially be fiber was successfully developed in 1970 by Corning Glass Works, with attenuation low enough for munication purposes(about 20dB/km), and at the same time GaAs semiconductor lasers were developed that were p
