Up to four traces can be overlaid on the display for analysis and comparison.

This is useful for evaluating connection point locations and loss after installing multicore fiber.

Merges the two traces measured from both directions and finds the correct splice loss.

Connection point 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.

Makes it simple to check aged deterioration of fibers or connection points, or fluctuation in loss between fibers, and other phenomena.

Finds the total return loss in specific portions of the fiber.

This type of evaluation is often requested because the multiple reflections from optical fiber networks can effect signal light from transmitters (cable TV etc.).

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 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 screens as BMP, JPG or PNG files. TRB or TRD files saved on Yokogawa's previous AQ7250 and AQ7260 models can also be loaded.

Language Selection
In addition to English (standard), you can select a display language of French, Chinese, Korean, Russian, and others.

USB Function
USB connectivity makes it more convenient to output to external memory or printers, and to set up communication. The AQ7270 comes standard with two USB1.1 compliant connector ports (type 'A' and type 'B').
