So far our PMD testing has come back clear.

How have you done the PMD testing?

For verifying PMD and CD through an actual wavelength (not per-fiber, but through all the ADMs etc), I haven't really been able to find a good solution. Suggestions welcome.


All tests done per span on dark fiber.

CDs via a Nettest FD440: 1520nm to 1640nm
PMD via a PerkinElmer* device: Just at 1550nm.

Couldn't find a model number in the test results. Just a reference to PerkinElmer.
