To get started viewing OTDR Traces, click on the OTDR menu link on the top of the page to center the OTDR on the screen then click the 'Add Traces' button. You can select one or more traces from your local file system by highlighting the traces in the file browser and clicking open.
The Online OTDR supports Belcore SR-4731 file format traces which usually have the .sor file extension.
If you don't have any OTDR traces and still want to use the Online OTDR we have provided a number of sample OTDR traces you can download and use. Access these from the 'Sample OTDR Traces' button, select the traces you want. Once downloaded, you can open them as decribed above.
Once you have added your traces they will be displayed in the Trace Display List on the left of screen.
Once the traces are added, just click the check box next to the trace name. It will be displayed on the main trace display panel. To hide the trace just unselect it again.
When it loads the Onlne OTDR is in Zoom Mode and Display from Origin. This means the trace is anchored on the screen at 0Kms / 0dB (Display from Origin) and when you click and drag your mouse on the trace panel it will scale (Zoom) the trace panel display and any visible traces. Drag up and down for dB zoom in and out and drag left and right for distance zoom in and out.
To change to Pan Mode, click the Zoom / Pan Mode button and select Pan. Now when you drag the mouse on the trace panel the trace display will move left / right and up / down with your mouse but the trace display scale doesn't change.
To view the trace event table, load and display the trace as describe above then select the desired trace in the top Trace Info pull down menu that all displays the trace details relative to the A and B cursors.
The best way to learn is to see! We are working on some demonstration videos that we will uplaod shortly. In the mean time, trial what is descibed and learn what other OTDR functions are included.
