We report that stimulated Brillouin scattering (SBS) plays an important role in ultrahigh-speed bitwise phase-controlled optical time-division multiplexing transmissions such as in-phase and carrier-suppressed return-to-zero (RZ). We show that the optical power can easily exceed the SBS threshold for such high-speed coherent RZ signals. The SBS-induced performance limitation in a 160-Gb/s-520 km transmission is described in detail.
