RMS pulse width as a function of average loss per LPG for the cases in which two and four LPGs were used along the 4.3 km FMF. Insets are waveforms corresponding to different losses/pressures for 2 LPGs or 4 LPGs. Horizontal and vertical error bars are calculated from the standard deviation of RMS pulse widths and losses measured under the same condition.
