Modifying types of events
The types of events are detected automatically as a function of their optical signature.
This can sometimes lead the system astray, if reflection from a connector is too strong
(end of fiber?), if a splice has a very low insertion loss (slope?), etc. Similarly, some types
of events cannot be recognized automatically from their signatures (for example,
couplers, multiplexers, etc.). For this reason, it is advantageous in some cases to be
able to change the type of events.
To do this:
