OTDR 155
10 Using the OTDR as a Light
Source
Note: This function is available with the Source (SRC) optional software package
only.
If you want to perform measurements with a power meter and your OTDR
as a source, the OTDR port can transmit a special tone. This port can be
used only to transmit—not detect that tone.
CAUTION
Never connect a live fiber to the OTDR port without a proper setup.
Any incoming optical power ranging from –65 dBm to –40 dBm will
affect the OTDR acquisition. The way the acquisition will be
affected depends on the selected pulse width.
Any incoming signal greater than 10 dBm could damage your OTDR
module permanently. For live-fiber testing, refer to the SM Live port
specifications for the characteristics of the built-in filter.
