We experimentally characterise the performance of two different 150nm (1470-1620nm), ~14dB gain Raman amplifiers consisting of hybrid distributed-discrete and discrete-discrete configurations. The hybrid scheme improves S-band OSNR and Q2-factor of 120Gb/s PM-QPSK signals after 63km transmission by >4dB and 1dB respectively compared to discrete-only design.
