当前的局域网（LAN）带宽需求>1 Gb/s，这正在推动多模光纤（LAN骨干中的主要光纤）的带宽-距离乘积的极限。为了克服这些限制，低成本和紧凑的波分复用方案的演示。通过300和100米的62.5/125-/spl mu/m多模光纤，分别实现5和10 Gb/s的总比特率。四个垂直腔面发射激光器在820、835、850和865 nm的波长下使用，每个以1.25或2.5 Gb/s的比特率操作。该技术提供了一种实用的解决方案，可在LAN中实现高达10 Gb/s的比特率。
Current local area network (LAN) bandwidth demands of >1 Gb/s are pushing the limit of the bandwidth-distance product of multimode fiber, the predominant fiber in LAN backbones. In order to overcome these limitations, a low-cost and compact wavelength division multiplexing scheme is demonstrated. Aggregate bit rates of 5 and 10 Gb/s are achieved through 300 and 100 m of 62.5/125-/spl mu/m multimode fiber, respectively. Four vertical-cavity surface-emitting lasers are used at wavelengths of 820, 835, 850, and 865 nm with each operating at a bit rate of 1.25 or 2.5 Gb/s. This technology provides a practical solution for reaching bit rates up to 10 Gb/s in the LAN.
