Abstract
A 50-GHz channel spaced dispersion-compensated interleaver pair for a metro add-drop network application was demonstrated using a recirculating loop. After five cascaded nodes (ten interleavers), a 2.5-dB sensitivity differential at bit-error-rate level around 10 -9 was observed between the compensated and uncompensated pairs within a ±10-GHz detuning frequency window. © 2005 IEEE.
