optics specified to reach 1600 ps/nm. As part of the effort within the Optical
Internetworking Forum, four semiconductor companies (AMCC, Broadcom, Scin-
tera Networks, Vitesse) with EDC solutions experimentally demonstrated the
feasibility of this application code [54], which also utilizes the negative-chirp
optical modulation and the beneficial self-phase modulation effect to overcome
chromatic dispersion.
Electronic Compensation of PMD
The first-order effect of PMD is known as a DGD between two principal states of
polarizations and produces a notch in the frequency spectrum of the direct-detected
signals. Electronic equalization compensates for
