An optical power meter is a device used to measure the power in an optical signal, typically in fiber optic systems. It consists of a calibrated photodiode sensor, a measuring amplifier, and a display that shows the measured optical power and the selected wavelength . The sensor is wavelength-dependent, so the meter must be set to the correct test wavelength to ensure accurate readings. Optical power meters can be stand-alone handheld or bench instruments, or integrated into larger systems for advanced testing .
An optical light source provides a stable, known optical signal for testing fiber links. These sources can be single-mode or multimode lasers and are available in various wavelengths to match testing requirements, such as 850/1300 nm for datacom or 1310/1550 nm for WDM and FTTx applications . Light sources are designed to be rugged and portable for field use, ensuring reliable measurements during installation, maintenance, or troubleshooting .
When an optical power meter is paired with a light source, the combination is called an Optical Loss Test Set (OLTS). This setup allows technicians to measure absolute optical power and end-to-end optical loss in fiber links . OLTS devices may include multiple power meters to measure optical return loss or bidirectional loss for higher accuracy. Portable OLTS solutions are compact, user-friendly, and suitable for field testing across networks like FTTH, Ethernet, CATV, and enterprise systems .
