The FOT-300 OLTS has both a built in power meter and light source for bi-directional testing without technicians needing to exchange equipment.

The FOT-300 is the most optimized OLTS on the market; it offers up to three singlemode or two multimode wavelengths on a single port.

• Auto-Wavelength Recognition
• Distant Referencing
• No offset Nulling
• FTTx Ready units available with 1490nm
• Factory Warranty – 3 years

KEY FEATURES
Highly optimized OLTS integrating a power meter port and up to three singlemode sources or two multimode sources on a single port Power autonomy of 260 hours Three-year warranty and recommended calibration interval, for dramatically reduced cost of ownership Ergonomic, eye-catching handheld package

Auto-Wavelength Recognition
The FOT-300’s built-in source can transmit with a wavelength-identification digital encrypted protocol, so that any compatible unit—the FPM-300 Power Meter and the FOT-300’s receiver—can automatically use the proper calibration parameters.

This feature reduces the need for communication between the two technicians and decreases the potential for error.

Distant Referencing
Signal encrypting can also give the receiving end information on the power to be used as reference, helping ensure efficient referencing, even when the two units are far apart.

No offset nulling
Thanks to its unique design, the FOT-300 Optical Loss Test Set reduces measurement time in typical measurement situations, as the need for an offset nulling is eliminated.

FTTx-Ready
EXFO’s FLS-300 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.
