AUTION
If you see that a channel is missing or the power level detected is
much lower than expected, you can switch to the OTDR application
on your module or an iOLM to troubleshoot the situation.
However, troubleshooting a live network is a delicate task
regardless of the method used and you must pay attention to the
following instructions before proceeding:
³
The signal that the OTDR or iOLM will receive must be below the
live fiber threshold. Live power over -50 dBm will degrade
OTDR/iOLM performance and eventually prevent you from
starting the measurement.
³
Avoid damaging the SFP. You might have to disconnect the SFP
at the end of the link under test. If you are using an iOLM and
have purchased the iOLM Advanced (iADV) option, you can use
the safe mode, which is designed to avoid damaging SFPs.
