The OCPM-18 Optical Power Meter has an absolute accuracy of <±0.5 dB and a power resolution of 0.01 dB.

Accuracy and Resolution

The OCPM-18 is designed for precise optical power measurements across a wide wavelength range of 1270 nm to 1610 nm. Its absolute accuracy is specified as less than ±0.5 dB, ensuring reliable readings for CWDM, PON, and LTE systems. The power resolution is 0.01 dB, allowing detection of very small changes in optical power, which is critical for network testing and calibration tasks .

Wavelength and Measurement Range

The meter supports 18 CWDM wavelengths: 1270, 1290, 1310, 1330, 1350, 1370, 1390, 1410, 1430, 1450, 1470, 1490, 1510, 1530, 1550, 1570, 1590, and 1610 nm. It can operate in both auto and manual scan modes, providing real-time measurements or selective wavelength readings . This flexibility ensures accurate power readings across multiple channels in optical networks.

Additional Features Affecting Accuracy

• Automatic wavelength and power detection reduces human error during measurements .
• Interchangeable optical connectors (FC, ST, SC, LC) maintain consistent coupling efficiency, which is important for measurement repeatability .
• Portable design with rechargeable battery allows stable operation in field conditions without compromising accuracy .

Summary

The OCPM-18 is a high-precision optical power meter suitable for professional optical network testing. Its <±0.5 dB accuracy and 0.01 dB resolution, combined with multi-wavelength support and automatic detection features, make it reliable for both laboratory and field applications .
