The inventions invention relates to a generic re-configurable WDM optical cross connection device which may be viewed as an optical network element comprising transport interfaces optionally along with tributary interfaces. An switch system includes a plurality of switch modules each essentially including a pair of R-channel input collimators on one side and a pair of R-channel output collimators on the other side with a switching prism moveably positioned therebetween in an existence/active or non-existence/inactive manner. A pair of input fibers are respectively connected to the two input collimators and an pair of output fibers are respectively connected t the two output collimators. A plurality of jumper fibers cascading said switch modules together.
