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.
