Up to 24 Individual Optical Power Meters

Each OP710 can be built with up to 24 individual optical power meters capable of measuring output power simultaneously. These power meters are compatible with our entire standard range of adapters to test any combination of connector types.

Robust Operative Ranges

The OP710 is available with both InGaAs and Silicon detectors, each with its own optimal wavelength spectrum and measurement range. Choose the detector type, size, and appropriate adapter to best fit your application.

  • Measurement range
    InGaAs: +6dBm to -72dBm
    Silicon: +3dBm to -65dBm
  • Broad wavelength spectrum
    InGaAs: 830nm to 1700nm
    Silicon: 400nm to 1100nm
Industry-Leading Accuracy

You can count on each detector of the OP710 to provide the speed and accuracy needed to meet the most demanding test requirements. Measure at speeds of up to 80 samples/second with an accuracy for relative measurements of ± 0.02dB* and front panel display resolution down to 0.001dB.

* For signals varying a maximum of 5dB.

Versatile Applications

When paired with the right source and software, test systems with the OP710 can serve all kinds of functions. Whether you need long-term discontinuity measurement, high variability production testing, or stability measurement, a test system that includes the OP710 is the way to go. As your needs change and you shift to new types of testing, the applications for the OP710 can change with you.
