That means the signal never leaves the fiber. This is exciting because we can perhaps think about putting some of the functions now done outside the fiber into [it]. |
The importance of these devices cannot be overstated. |
This advance is the basis for a technology that could build a large range of devices inside an optical fiber. If the signal never leaves the fiber, then it is faster, cheaper and more efficient. |
What's surprising is how perfectly the process works. |
