D. Sandel et al., AUTOMATIC POLARIZATION MODE DISPERSION COMPENSATION IN 40GBIT S OPTICAL-TRANSMISSION SYSTEM/, Electronics Letters, 34(23), 1998, pp. 2258-2259
Polarisation mode dispersion impedes the development of high capacity
optical trunk lines but can be compensated for by an adaptive compensa
tor in the receiver. By using three polarisation mode dispersion penal
ty extraction signals, differential group delays exceeding one bit dur
ation are compensated for in a 40Gbit/s optical transmission system fo
r the first time.
