When beams of light pass through a fiberopticcable, they tend to degrade.
当光束通过光纤，光强度趋于降低。

This produces a "waveguide," which functions like a one-atom-thick fiberopticcable.
这就形成了一个“波导管”，就像一个单原子厚度的光纤电缆。

One team of engineers can concentrate on developing the best possible wireless data service, while another can learn how to squeeze more and more bits through fiberopticcable.
