The Impact™ Plus 85-Ohm Backplane Connector System inherently provides
customers with Plus technology with the use of a common ground clip in
the daughtercard. Electrical characteristics and performance are improved
by reducing Insertion Loss Deviation (ILD) and cross-talk performance is
improved by enabling use of longer channels.
