Optical power meters are available as stand-alone bench or handheld instruments or combined with other test functions such as an Optical Light Source (OLS), Visual Fault Locator (VFL), or as sub-system in a larger or modular instrument. Commonly, a power meter on its own is used to measure absolute optical power, or used with a matched light source to measure loss.
Power Meter
- The ability to set the unit to read 0 dB at a reference power level, typically the test source.
- The ability to store readings into internal memory, for subsequent recall and download to a computer.
- The ability to synchronize the wavelength with a test source, so that the meter sets to the source wavelength.
