Jm. Jacob et al., 10-GB S TRANSMISSION OF NRZ OVER 10,000 KM AND SOLITONS OVER 13 500 KM ERROR-FREE IN THE SAME DISPERSION-MANAGED SYSTEM/, IEEE photonics technology letters, 9(10), 1997, pp. 1412-1414
A dispersion management scheme that is capable of supporting both disp
ersion-managed solitons and nonreturn-to-zero (NRZ) data formats as we
ll as intermediate formats is demonstrated for error-free long-haul tr
ansmission at 10 Gb/s in excess of 9500 km. This experimental tool can
be used to directly compare the different data formats. Our results s
uggest that a format between standard solitons and standard NRZ, such
as dispersion-managed solitons or phase-modulated NRZ, may have signif
icant advantages.
