Capacity limits of information transport in fiber-optic networks

Phys Rev Lett. 2008 Oct 17;101(16):163901. doi: 10.1103/PhysRevLett.101.163901. Epub 2008 Oct 13.


The instantaneous optical Kerr effect in optical fibers is a nonlinear phenomenon that can impose limits on the ability of fiber-optic communication systems to transport information. We present here a conservative estimate of the "fiber channel" capacity in an optically routed network. We show that the fiber capacity per unit bandwidth for a given distance significantly exceeds current record experimental demonstrations.
