- From the limited information above, I'd say that WDM refers to
- optical wavelength division multiplexing. That is, using different
- wavelengths of light over optical fibre to provide medium access to
- multiple users. It's analogous to the way radio spectrum is currently
- used, and obviously is confined to all-optical networks.
