因特网接入和高速数据传输的巨幅上升提高了对光纤容量的需求。如果通过给网络敷设新的光纤来增加容量 ,不但成本高 ,而且限制了未来扩容的灵活性。可喜的是 ,光纤设备的技术进展使人们能够从单根光纤中获得的容量越来越多 ,并且科学家还在继续为光纤技术开创新的里程碑。朗讯? The huge increase in Internet access and high-speed data transmission has increased the need for fiber capacity. If you add new fiber to the network to increase capacity, not only the high cost, but also limits the flexibility of future expansion. The good news is that advances in fiber optic equipment have enabled more and more people to get the capacity from a single fiber and scientists continue to set new milestones in fiber technology.
