What is the primary function of an optical power meter (OPM)?

• A. To repair fiber-optic cables
• B. To measure the power in an optical signal
• C. To splice fiber-optic cables
• D. To convert signals to electrical form

Answer: (B)

The primary function of an optical power meter (OPM) is to measure the power in an optical signal. This tool is essential in the field of fiber optics as it quantifies the optical power level, typically expressed in units such as dBm or milliwatts. By providing this measurement, technicians can assess the performance of fiber optic links, troubleshoot issues, and ensure that the system operates within specified limits. Measuring power in an optical signal allows technicians to confirm that signals are transmitted effectively through the fiber medium, detect possible losses due to bends, connections, or splices, and evaluate the quality of the installation. This makes the optical power meter a crucial instrument for maintaining and optimizing optical communication systems.
