5. Select the operation mode ( CW , 270 Hz , 1000 Hz , or 2000 Hz ) for the test.
CW (Continuous Wave)
: Select to continually measure level, loss, and reflectance
in optical components.
270 Hz, 1000 Hz, 2000 Hz ( Pulse) . Select this option to send intermittent light
pulses. In some cases, this makes it easier to identify faults (than continuous light). It
can also be used with audible detectors (toners) that can identify faint light or in well-
lit (bright) environments.
Loop: Loop ON will enable lasers to cycle through all available lasers automatically.
6.10.2 Using the Optical Light Source
To use the OLS:
1. Connect a patchcord between the OLS and OPM test ports.
2. Select
Optical Light Source from the main menu. The OLS screen appears.
3. Tap Turn ON to power on the OLS.
4. If WaveID is available, tap
Loop
mode, to auto cycle through all available wavelengths on
the test port. The laser will change every three seconds.
Note: WaveID feature will not work with modulated light signals.
5. When testing is complete, tap Turn OFF to power off the OLS, and then disconnect the
cable and replace the port covers.
RXT-4111 DWDM OTDR Laser Stabilization
The RXT-4111 DWDM OTDR test module offers advanced TEC laser
stabilization for hot and color weather operating conditions. If the
optimal temperature for usage has not been reached,
a Laser
Stabilization message appears.
