Contentionless

Allows the dropping of same-wavelength lightpaths from more than one ROADM port. For a ROADM to be fully contentionless, there needs to be as many drop units as there are ROADM degrees.

re: Contentionless

Apparently, it is nothing more than wavelength interchange or conversion capability. If the same wavelenght from two different directions is in contention on the same outgoing direction, the solution is to convert it on the node into a free wavelength. This solves the contention.
