This letter presents the phase-shaped binary transmissions (PSBT), which allow to bridge more than 200 km in the linear regime over standard dispersive fibers. These transmissions are based on /spl pi/ phase shifts occurring in the middle of some "0" hits inside a binary sequence. An analytical explanation is given. This letter also explains why 2-intensity level duobinary transmissions, which are a particular case of PSBT, were able to bridge experimentally up to 243 km.
