Abstract

The concept of compensating for chromatic dispersion of optical fiber by concatenating different fibers with dispersion of opposite signs was proposed in the early stage of single-mode fiber development.¹ It was, however, only a few years ago, obviously triggered by the rapid success of erbium-doped fiber amplifiers (EDFAs), when dispersion-compensating fibers (DCFs) began to be widely developed to combat the large chro- mafic dispersion of conventional single-mode fibers (SMFs) in the 1.55-μm window.²
