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

The primary function of an optical power meter (OPM) is to measure the power in an optical signal. This tool plays a crucial role in fiber optic communications by quantifying the amount of light power traveling through a fiber. This measurement is essential for ensuring that the optical signals being transmitted are at the correct levels to maintain signal integrity and quality, allowing for effective data transmission.

When assessing network performance, it's important to know the power levels to identify any potential losses, which could affect the overall efficiency of the system. Accurate power measurements facilitate troubleshooting and help technicians optimize network performance by ensuring that the optical signals are within the acceptable range for the equipment being used.

Amplifying an optical signal refers to the actions taken using devices like optical amplifiers, which is not within the scope of the OPM's functionality. The conversion of electrical to optical signals is a function of other types of equipment, such as transmitters and transceivers, which create the optical signals to be measured. Fiber splicing involves connecting fiber ends together physically, often performed by a different set of tools and techniques not related to the measurement of optical power.
