3.1.1.3 Phase EOM transmission measurement (P
out
):
Fig. 22
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.
3.1.2 W/O OPTICAL CONNECTORS (CUT-BACK METHOD)
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.
