Noyes OPM5 Power Meter
The OPM 5 is used to perform diagnostic and evaluation measurements associated with fiber optic transmission systems and cable plant. Applications for the OPM 5 will be found within the telecommunication, cable television, data network, and industrial control industries.
The OPM 5 measures absolute power (in dBm or µW ) and loss (dB). Absolute power expressed in dBm is the amount of optical power received by the detector as compared to 1mW (0dBm=1mW). Measuring dBm is useful for verifying the output power of a transmitter and determining system losses.
Loss is the difference in optical power from a known input (the reference level) and the output power at the opposite end of the fiber under test. The OPM 5 can display dB loss directly after a reference level has been set. Loss measurements are used to qualify cable plant links and fiber optic jumpers.
Microwatts is also a way to measure absolute power. Some manufacturers specify their transmission equipment in watts instead of dBm. The OPM 5 offers the ability to measure watts for convenience when verifying output power of transmitters. For accurate results, always be sure to set the OPM 5 to measure the same wavelength as the output of the optical light source.
