FOTP-171 was rewritten to include EF for all methods.  It still includes overfilled launch conditions, and the mode filter launch conditions as alternatives.Method A:  Single cable reference.
Method B: Two cable method, with a recommendation to measure multimode cabling in two directions by swapping the ends.
Method C: Replacement method (golden cable) for hybrid cable styles.

IEC 61300-3-4

Insertion Method A:  Splice between loss.  DUT is spliced between a length of fiber for the measurement.
Insertion Method B: Single reference cable method.  DUT connected at end of reference cable for measurement.
Insertion Method C: Two reference cable method.  Two reference cables referenced together and DUT connected between them for measurement.
