Product description

Polarization Analyzing OFDR — PolaMagic™

The patent-pending technology obtains space-resolved reflection as well as birefringence or polarization mode dispersion (PMD) information for optical paths consisting of optical fibers, micro-optical components, and waveguides.

Users can measure and record stress levels as well as reflected energy and do predictive analysis of reliability. The data gathered by the OFDR-1000-A is independent of temperature; therefore, data gathered over time does not require temperature normalization.

The OFDR-1000-A can be used with various tunable lasers, such as those from Keysight, Newport, Yenista, or Santec. This flexibility offers the user the opportunity to make full use of his laser resources and reduce the cost of making OFDR measurements.

Applications:

Fiber optic component quality inspection
Fiber optic module/system QA
Distributed stress sensing
Structural health monitoring
Fiber optic component troubleshooting

High spatial resolution for reflection: 20 μm
High spatial resolution for stress: 2 mm
