Optical Power Meter (OPM)
Function
- An OPM measures the power level of optical signals in fiber (in dBm or mW). It’s used to verify signal strength and loss after transmission.
Features
- Works with different wavelengths (850 nm, 1310 nm, 1490 nm, 1550 nm, etc.).
- Can be paired with a light source for insertion loss testing.
- Auto wavelength detection and memory storage in advanced models.
Applications
- Fiber network troubleshooting.
- Measuring optical signal output from transmitters or after long links.
- Certifying fiber links.
