Abstract :
We demonstrate a novel dispersion-tolerant transmission scheme based on a three-level duobinary-encoded polarization-shift keying (PoISK) transmission format. Simulations over standard single-mode fiber demonstrate an improvement in the chromatic dispersion-limited transmission distance from /spl sim/65 km, using conventional nonreturn to zero intensity modulation to /spl sim/195 km for duobinary PoISK.
