Polarization Analyzing OFDR—PolaMagic™
The OFDR-1000A is a polarization analyzing optical frequency domain reflectometer (PA-OFDR), a breakthrough instrument capable of analyzing polarization evolution along an optical fiber. 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-1000A is independent of temperature; therefore, data gathered over time does not require temperature normalization.
The OFDR-1000A 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.

Notes
1. Typical. The user's tunable laser must be a single mode tunable laser without any mode hopping, with a wavelength scanning speed of 10 nm/s.
2. Typical value for wavelength tuning range Δλ >80 nm for a maximum measurement distance of 5 meters. Otherwise, spatial resolution is 10 × 80/Δλ μm.
3. Refer to technical specifications of user's laser. The laser wavelength must be in the C or L bands.
4. This is a typical range for a two-way value between a strongest reflection greater than −30dB and the noise floor, averaged over ten (10) measurements. Without averaging, the range is reduced by 5 dB.
5. Measured with 0.5 m integrated width.
6. Two-way loss before backscatter reaches the noise floor and insertion loss (IL) measurements are no longer possible.
7. This is for a single scan measurement for a laser wavelength tuning speed of 20 nm/s.
