About the optical tools
The Optical Power Meter is a JDSU accessory used to measure optical power.
– The MP-60 meter measures 850, 1300, 1310,1490, and 1550 nm wavelengths
– The MP-80 meter measures 980, 1310,1480, and 1550 nm wavelengths
The features of the Optical Power Meter include:
– Takes power measurements for all single-mode and multi-mode connectors via USB 2.0
connection.
– Measures optical power with multiple pre-calibrated wavelengths.
– Integrates digital power measurements, fiber inspection, and analysis into a single, unified
work sequence.
Measuring optical power
To measure optical power, a Power Meter must be inserted into the USB port.
To measure optical power
1 From the Main menu, select Optical Power.
The Optical Power Setup menu appears.
2 Specify the settings.
3 Connect the Optical Power Meter to the USB connector on the right side of the instrument.
4 Connect the optical patch cord to the power meter.
5 Select Optical Power Test Menu.
This menu item appears only when an Optical Power Meter is plugged into the USB
connector; otherwise, “Insert USB Power Meter” appears.
The power meter test results appear. The measurement begins as soon as the test is
launched.
Table 17 Optical Power Meter Settings
Setting Description
Wavelength To measure a specific wavelength, select the wavelength.
Use Auto to automatically detect the wavelength.
NOTE: Auto-Detect requires a JDSU optical source.
Units Specifies the absolute measurement unit: mW or dBm.
LED Threshold Specify the LED threshold (in dBm). This specifies the threshold for the power
LED on the Optical Power Meter. Solid indicates the power is below the thresh-
old (low power), flashing indicates the power is above the threshold.
Pass/Fail Thresh. Specify the pass/fail threshold (in dBm) for the test. If the measured power is
below the threshold, it fails.
Pass/Fail Enable Specify whether to run the pass/fail test.
Meter FW Rev Reports the firmware rev of the attached power meter.
