Continuous-Sweep PMD/PDL-Measurement

The well-known Jones-Matrix-Eigenanalysis (JME) has become the standard method for measuring Polarization Mode Dispersion (PMD) or differential group delay (DGD) of optical fibers and components. Although known to be the Golden Method a couple of difficulties are associated with the JME which have been accepted in the past.

Adaptif PHOTONICS has pushed the limits of the estabilshed JME in the following ways:

• Single-sweep measurement of: DGD, PDL, Power/Loss, 2nd-order PMD (Depolarization + PCD)
• Improved measurement speed: Covers a wavelength range of 100nm within 10 seconds.
• Improved robustness: Fibers are allowed to move during measurement.

Example measurements:

• Differential group delay (DGD) of a 100km standard fiber.
• Polarization dependent loss (PDL) of a fiber Bragg grating.
• Loss curve of a narrow-band optical filter.
• Long-term DGD measurement of a fiber link.
