Our investigations clearly show a sensitivity gain for low-duty-cycle RZ coding, even if the receiver bandwidth is not increased compared to that employed for NRZ signals. This improvement presupposes constant energy per pulse, i.e, that the transmitter-and hence any optical booster amplifier-is not limited by peak power but by average power.
