Fast packet routing in a 2.5 Tb/s optical switch fabric with 40 Gb/s duobinary signals at 0.8 b/s/Hz spectral efficiency

Abstract

We demonstrate error-free 40 Gb/s duobinary packet routing by fast wavelength switching on two ports in a 64/spl times/64 passive optical switch fabric. Switching in less than 45 ns for all channel combinations and burst-mode clock recovery in less than 15 ns are achieved.
