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.
