Designed for first-class ease of use, the FOT-600 features a pass/fail LED indicator; what’s more, it lets you set your own thresholds for absolute or relative loss measurements.

Thanks to its memory capacity of 1000 data items and its built-in reporting software, the FOT-600 facilitates data management and enables data transfer to a PC via USB connection. Create and customize a complete test report, including certification of the link with pass/fail information.

When using the FOT-600 in Auto-Switching mode, the light source automatically toggles between available wavelengths. The power meter recognizes the wavelength in use and switches to the proper calibration parameter. With a press of a button, you can store results for all wavelengths at once, providing easy and error-free testing.

Thanks to its unique design, the FOT-600 Optical Loss Test Set reduces risk of error and measurement time in typical measurement situations, as the need for an offset nulling is eliminated.

In addition to network-link qualification features, the highly accurate FOT-600 offers over 40 calibrated wavelengths, including all CWDM wavelengths. What’s more, it lets you measure power fluctuations with its Hold Min/Max Power function.

EXFO’s FOT-600 allows for the testing of passive optical networks (PONs) at 1310 nm, 1490 nm and 1550 nm, the three wavelengths recommended by the ITU-T (G.983.3) for PONs.

Like all EXFO portable instruments, the FOT-600 is built for top ruggedness and versatility, perfect for the harshest test conditions.

It features a keypad/LCD backlight, for easy operation in darker environments. What’s more, it is powered by a rechargeable battery.
