Abstract
Selecting a wavelength and a route includes facilitating communication through routes among nodes. Each route is associated with a plurality of wavelengths and comprises one or more segments that couple one node to another node. A polarization mode dispersion value is determined for each wavelength of each route to yield polarization mode dispersion values for each route. A wavelength and a route are selected according to the polarization mode dispersion values.

A computer-readable medium having computer-executable instructions, when executed by a computer configured to:
- facilitate communication through a plurality of routes among a plurality of nodes, each route associated with a plurality of wavelengths, each route comprising one or more segments, a segment coupling one node to another node;
- determine a polarization mode dispersion value for each wavelength of each route of the plurality of routes to yield a plurality of polarization mode dispersion values for the each route;
- and
- select a wavelength and a route according to the polarization mode dispersion values of the plurality of wavelengths.
