Notes

Experimental work that led to this publication, including the measured loss profile used here, was carried out in lab 4103 of building 46, University of Southampton, circa 2014 (D. Richardson’s group, J. Price’s lab, optoelectronics research centre).

Measured loss data file is component_loss_profiles/976_1030_fused_WDM.txt Pigtails assumed to be HI1060.
