Setting proper wavelength
Proceed test with same fiber but different wavelength we will get different result. Longer the testing wavelength is,more
sensitive of the bending, in below chart ,first splicing point has bending problem,splicing loss value under 1550nm is bigger
than that under 1310nm. the other points are similar with 1310nm and 1550nm.This phenomenon indicate that this fiber is just
bended at the first point. If it's possible please alway compare the point state under 1310nm and 1550nm and judge whether
it's bended or squashed(see Figure 5).
Setting proper test time
In averaging mode, long testing time could reduce noise during the data sampling and Improve precision to get better and
smoother curve(see Figure 6).
