D. Penninckx et al., THE PHASE-SHAPED BINARY TRANSMISSION (PSBT) - A NEW TECHNIQUE TO TRANSMIT FAR BEYOND THE CHROMATIC DISPERSION LIMIT, IEEE photonics technology letters, 9(2), 1997, pp. 259-261
This letter presents the phase shaped binary transmissions (PSBT), whi
ch allow to bridge more than 200 km in the linear regime over standard
dispersive fibers. These transmissions are based on pi phase shifts o
ccuring in the middle of some ''0'' bits inside a binary sequence, An
analytical explanation is given. This letter also explains why 2-inten
sity level duobinary transmissions, which are a particular case of PSB
T, were able to bridge experimentally up to 243 km.
