Brand: Fluke Networks
A Fiber Optic Light Source (FOLS) is an essential device that emits a stable, known optical signal into a fiber optic cable. When paired with an Optical Power Meter (OPM), it allows technicians to perform accurate attenuation measurements and verify the integrity of fiber optic links and terminations. This tool is crucial for ensuring low signal loss and optimal performance in fiber optic networks.
Type: measuring
Price Range: $100-300
Pros
- Enables accurate attenuation (loss) measurements when paired with an OPM.
- Verifies proper termination and splicing, identifying bad connections or breaks.
- Compact and often battery-powered for portability in the field.
Cons
- Requires an Optical Power Meter for complete attenuation testing; not a standalone solution.
- Different FOLS models are needed for various fiber types (multimode/singlemode) and wavelengths.
- Calibration may be required periodically to ensure measurement accuracy.
