Phase EOM transmission measurement (P

Note: This measurement includes an uncertainty attributed to the optical
connector’s
misalignment and mating sleeve.
Depending on the quality / compatibility of each optical element (connectors, mating sleeve), we
estimate that the excess optical losses are as following:
FC/APC @1550 nm:
IL
≤
0.25 dB per connector
FC/APC @1060 nm:
IL
≤
0.4 dB per connector
FC/APC @850 nm:
IL
≤
0.5 dB per connector.

The cut-back method is a well-known set up to avoid the uncertainty induced by optical
connectors. However, this method needs the use of a fiber fusion splicer equipment.
