ITU approves novel dispersion test
technique
EXFO's proprietary test method for characterising polarisation mode dispersion has been approved by the International Telecommunication Union.
EXFO's proprietary test method for characterising polarisation mode dispersion (PMD) has been approved by the International Telecommunication Union (ITU) EXFO's test method, better known as generalised interferometric (Ginty) analysis, improves on and extends the scope of the traditional interferometric (Tinty) model: optical links, which contain erbium-doped fibre amplifiers (EDFAs), can be tested end-to-end for PMD through Ginty analysis; PMD, down to experimental uncertainty, can now be measured (6fs, typical); and Ginty results are traceable to a reference test method known as Stokes Parameter Evaluation

Chromatic dispersion can be characterised with high accuracy from a single fibre end and testing polarisation mode dispersion from a single end is also possible.
The ITU became the third leading standards body to approve Ginty analysis.
EXFO's test method has also been standardised by the International Electrotechnical Commission (IEC) and the Telecommunications Industry Association (TIA).
"In keeping with EXFO's 'expertise reaching out' reputation, we are proud that our research efforts have further improved test and measurement standards in our industry", said Gregory Schinn, Chief Technology Officer of EXFO's Optical-Layer Product Group.
"This method is the only test approach that is truly applicable, without any limits or restrictions, in all field-related PMD measurements".
"More importantly, we have taken this technological expertise and developed the only portable PMD analyser on the market that is based on Ginty analysis".
"Its impressive capability has been demonstrated by testing over an optically amplified transatlantic link from Nova Scotia to Ireland in a hero experiment - an unmatched demonstration".
