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.
Optical component manufacturers who supply fibre networks must test their products at design and manufacturing stages to ensure that PMD and second-order PMD are within acceptable ranges for good-quality transmission on optical networks.
These measurements are critical for upcoming 40Gbit/s systems and components.
Second-order PMD is related to the variations of the principal state of polarisation (PSP) as a function of wavelength.
The new capability will allow manufacturers to easily and quickly measure the PMD and second-order PMD of optical components.
PMD can accumulate and then impair service on a fibre-optic network.
As network data rates climb to 40Gbit/s and beyond, PMD becomes increasingly more challenging due to the effect of second-order PMD.
"PMD is one of the biggest obstacles facing the deployment of 40Gbit/s systems", said Mario Larose, Vice-President of Marketing at EXFO.
"With the first-ever second-order PMD capability, the femtosecond PMD analyser becomes an essential solution for optical component manufacturers who need to overcome this obstacle".
"As an R and D and manufacturing tool, the femtosecond PMD analyser is designed to help manufacturers profit from the current 10Gbit/s and the emerging 40Gbit/s markets".
