Return loss for the entire fiber under test, including fiber backscatter and reflections and relative to the source pulse, is called Optical Return Loss (ORL). It is also given in units of dB, but always a positive

A uni-directional test will be conducted on all pigtail splices with no greater than a .8 dB loss accepted. Any loss higher than a .8 dB after 5 repeated attempts results in the replacement and re-splicing of

Some designs of these fibers have relatively high backscattering coefficients (“K”), primarily due to a larger mode field diameter (MFD). The difference in backscatter at the pigtail splice does not prevent
