[1] applies to output connector option 020 (pigtailed fiber port). For option
021 (straight contact output connector) and option 022 (angled contact
output connector) the PDL of the individual connector or connection
may by far exceed the specified accuracy.
[2] higher PDL/PDG/PDCR values may be measured with increased
uncertainty.
[3] with higher insertion loss or source power <-10 dBm, PDL/PDG/PDCR
values may be measured with increased uncertainty.
