    It is essential to increase or decrease storage time of a Dual Loop Optical Buffer (DLOB) by properly selecting fiber loop length. We experimentally investigate the performance constraint of DLOB owing to the Four-wave mixing (FWM). Our results show that some parameters, such as the control signal wavelength, length of fibre loop, types of fibre have strong impacts on the performance of DLOB. The storage time can be increased by power compensation, but the signal become degraded after several loops due to FWM. To decrease the buffer time, the power of the control signal is increased and high-nonlinear fibre is selected to shorten the fibre loop, but the FWM can not be eliminated and has a critical impact on the performance of DLOB.
