Belden 1421A is a Computer EIA RS-232/422 Cable with 4-Pair, 24 AWG stranded (7x32) tinned copper conductors, Datalene insulation, an overall Beldfoil shield (100% coverage), with 24 AWG stranded tinned copper drain wire in a PVC jacket.
A Multi-Pair Cable is an electronic cable that consists of multiple groups of twisted-pair circuits. This construction allows many wires to be bundled into one package, reducing electromagnetic interference and crosstalk, as well as providing easier installation.
