U2W, U160 and U320 drives (all LVD devices) do NOT provide any means for termination so you will need to use a cable terminator or put another drive with termination option at the cable end.
Some SCA2 adapters (80 pin) have integrated terminators as well. As long as you're not trying to run U2W+ speeds you don't need an LVD/SE terminator, as simpler SE will do (preferrably of the active flavor).
