This unit
The EXFO FOT-300 Optical Loss Test Set is a handheld instrument that integrates a light source and power meter into a single unit for efficient optical power and loss measurement in fiber optic networks. It streamlines field testing, troubleshooting, and network certification through auto-wavelength recognition and distant referencing, eliminating offset nulling in typical measurement scenarios. The FOT-300 supports testing on passive optical networks at ITU-T recommended wavelengths and delivers 260 hours of battery autonomy using either an AC adapter or three AA batteries.
