Measurement Wizard Menu ACTIVE LINE ALARM -Checking for communication light Never disturb communication lines There may be concern that technicians inputting the OTDR measurement signal into the communication line could cause communication errors. The live line alarm monitors the fiber's optical power level and diplays an alarm message if it detects optical power at or higher than a specified threshold level, in order to warn the technician not to mistakenly feed the signal into the communication line. Active Line Alarm Message PLUG CHECK FUNCTION -Checking the connection with the OTDR Never spoil measurements with poor connections or dirty plugs The plug check function monitors the condition of the OTDR's optical input/output connectors and displays an alarm if the connection is not properly made. This function is useful for checking for damage, dirt, or other problems with optical plugs at the OTDR or on the fiber under test, and for helping technicians to remember to connect the fiber under test. 5 Plug Check Alarm Message Detecting Abnormal Events -Fault Event Display Function The fault event display function detects abnormal connection or reflection points and displays them. Of the events detected by the event detection function, abnormal events that cross a specified threshold value are highlighted in the event table and waveform display. Fault event Fault event Analysis results with Fault Event Display Fault Event Indication on the waveform Measurement with Comparison to Reference Waveform -Trace Fix Function You can freeze the display of one trace and overlap it with real time or averaged waveforms for comparison. This is useful to create a template when installing multicore fiber, or for checking aged deterioration during maintenance on existing fiber networks.

This is useful for evaluating connection point locations and loss after installing multicore fiber. Connection loss in lines where optical fibers of differing backscatter coefficients are connected can differ depending on the direction. In such cases, you can accurately determine the loss by measuring in both directions and taking an average. For Evaluation of Aged Deterioration For Evaluation of Total Return Loss --Differential Trace Analysis Displays the difference between two specified traces. --Section Analysis Finds the total return loss in specific portions of the fiber. Makes it simple to check aged deterioration of fibers or connection points, or fluctuation in loss between fibers, and other phenomena. This type of evaluation is often requested because the multiple reflections from optical fiber networks can affect signal light from transmitters (cable TV etc.). Smart File Function Because the AQ7270 makes it easy to differentiate between measured optical fibers--even complex ones--you can add arbitrary information to file names such as measured wavelength, ID number, tape number, or comments. You can also have the ID number or tape number automatically updated and saved after each measurement. Trace data can be saved in SOR and CSV format. Also, you can save screenshots as BMP, JPG, or PNG files. TRB or TRD files saved on Yokogawa's previous AQ7250 and AQ7260 models can also be loaded.
