Abstract
In repeaterless transmission systems, external modulation of the optical source has been preferred over direct modulation to reduce the influence of chromatic dispersion and recently systems beyond 500 km at 2.5 Gbit/s have been demonstrated.1,2 As these systems use dispersion-compensating fiber (DCF) due to the necessary spectral broadening for suppression of stimulated Brillouin scattering (SBS), the need for externally modulated sources is greatly reduced. Previously, transmission over 306 km of standard single-mode fiber at 2.4 Gbit/s3 and over 310 km at 1.8 Gbit/s using dispersion-shifted fiber4 have been demonstrated using direct modulation of the transmitter laser.
