EXFO Electro-Optical Engineering Inc. has introduced a new capability on the FPMD-5600 Femtosecond Polarization Mode Dispersion (PMD) Analyzer that enables optical component manufacturers to measure second-order PMD in devices such as narrowband DWDM channels and broadband components.
Optical component manufacturers who supply fiber 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 40-Gbit/sec systems and components.
Second-order PMD is related to the variations of the principal state of polarization (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, say EXFO representatives. PMD can accumulate and then impair service on a fiber-optic network. As network data rates climb to 40 Gbits/sec and beyond, PMD becomes increasingly more challenging due to the effect of second-order PMD.
