Calibration of FPM-300 Optical Power Meter

Specialty cable knowledge brief Published 12 Jan 2024

Prepared for preliminary research by the ZITHA SPECIALTY knowledge desk. Confirm fire performance, mechanical protection, loss budgets and installation requirements against current standards and product documentation.

The EXFO FPM-300 Optical Power Meter can be calibrated using auto-wavelength referencing with compatible source units or through professional calibration services to ensure accurate optical power measurements.Auto-Wavelength Calibration

The FPM-300 is designed to automatically use the proper calibration parameters when paired with compatible EXFO source units such as the FLS-300 or FOT-300. These sources transmit a wavelength-identification digital encrypted signal, allowing the power meter to automatically adjust its calibration for the specific wavelength being measured. This feature reduces manual errors and ensures consistent referencing even when the source and meter are physically separated .

Manual Referencing Procedure
  1. Connect the source (FLS-300 or FOT-300) to the FPM-300 using the appropriate fiber connector (FC, SC, ST, or LC).
  2. Select the desired wavelength on the power meter. Each wavelength must be referenced separately.
  3. Set the reference value by measuring the source power and storing it in the meter. This ensures that subsequent measurements reflect only the fiber loss or absolute power relative to the reference .
  4. Avoid disconnecting the reference test jumper during measurements to maintain accuracy. The FPM-300 supports multiple wavelengths commonly used in PON and FTTH networks, including 1310 nm, 1490 nm, and 1550 nm, as well as additional wavelengths up to 1625 nm .
Professional Calibration Services

For high-accuracy requirements or periodic verification, the FPM-300 can be sent to ISO-compliant calibration facilities. These services provide:

  • Traceable calibration to NIST standards
  • Verification across all calibrated wavelengths
  • Adjustment of the InGaAs detector for consistent performance
  • Certificates of calibration for documentation and compliance Professional calibration is recommended at intervals suggested by EXFO, typically every 12 to 24 months, depending on usage and environmental conditions .
Maintenance Tips for Accurate Calibration
  • Always inspect and clean fiber connectors before measurement.
  • Store the meter in its carrying case when not in use.
  • Avoid exposing the meter to extreme temperatures or humidity outside the specified operating range (-10 °C to 50 °C, 0–95% non-condensing), .
  • Replace batteries or use the AC adapter to prevent power interruptions during referencing. By following these procedures, the FPM-300 maintains high accuracy and reliability for optical power measurements in telecommunications, data communications, and other fiber optic applications.
