Monitoring Fibers in Real-Time Mode

The application allows you to immediately view sudden changes in the

fiber link. In this mode, the trace is refreshed instead of averaged until you

switch to average mode or stop the acquisition.

Note: You cannot reanalyze a trace in real-time mode.

Note: In real-time mode, the trace is refreshed at a slower rate when the graph

overview window is displayed.

Note: You can only use one wavelength at a time to monitor your fiber.

You can switch from real-time mode to the averaging time interval mode at

any time. You can also switch between wavelengths during an acquisition

(all wavelengths must be selected before starting the test).

To activate the real-time mode:

1. If your module supports singlemode, singlemode live, or multimode

wavelengths, specify the desired fiber type (for live-fiber testing, select

SM Live; for C fiber, select 50 m and for D fiber, select 62.5 m).

2. From the wavelength list, ensure that all the desired wavelengths are

selected.
