EXFO FPM-600 - Sending Source Power Value with Signal

35 FPM-600/FLS-600
Using a Light Source (FLS-600) or VFL
Sending Source Power Value with Signal
Sending Source Power Value with Signal
Your source can transmit a user-defined power value to compatible power
meters (such as FPM-600) through the fiber. If the reference source is far
from the power meter, you can connect your source to the power meter
to send the reference value. With this feature you can also correct for
power variations.
Note:
For details about how compatible power meters receive this power value,
see Referencing Your Power Meter to a Source on page 23.
IMPORTANT
The value sent is not (and will not affect) the source’s actual power.
It is a user-defined value that may not take the optical link’s loss
into account.
