IL @ 1310 and 1550 similar

If made properly, the cable assembly will test about the same at either 1310 or 1550.  1550 Insertion Loss results are generally better by a few hundredths of a dB, due to, in part, its lower fiber attenuation.    It’s normal that Insertion Loss values for a connector be ~0.01 - 0.05 dB better at 1550 than 1310.
