EXFO Electro-Optical Engineering Inc. announced today that its proprietary test method for characterizing polarization mode dispersion (PMD) has been approved by the International Telecommunication Union (ITU).

EXFO’s test method, known as Generalized Interferometric (GINTY) analysis, improves upon and extends the scope of the Traditional Interferometric (TINTY) model.

Optical links, which contain erbium-doped fiber amplifiers (EDFAs), can be tested end-to-end for PMD through GINTY analysis.

PMD, down to experimental uncertainty, can now be measured (6 femtoseconds, typical). GINTY results are traceable to a reference test method known as Stokes Parameter Evaluation.

The ITU became the third standards body to approve GINTY analysis. It has also been standardized by the International Electrotechnical Commission (IEC) and the Telecommunications Industry Association (TIA).
