Keywords:Transmission impairments and their mitigations

We investigated in detail the phase noise caused by guided acoustic wave Brillouin scattering (GAWBS) in digital coherent transmissions in various fibers. Small A_eff fiber is disadvantageous because of a large overlap between electric field and acoustic mode.
