Enhanced Shielded twisted-pair (STP-A) cable has how many separate foil-shielded twisted pairs?

Explanation:
Enhanced STP-A uses two separate foil shields, one around each of the two twisted pairs, to provide targeted EMI protection for the two signal paths used in the common 10 Mbps Ethernet configuration. This per-pair shielding helps reduce interference both from and to adjacent cables, which is especially important in noisy environments. Since only two pairs carry the data in that era of Ethernet, there are two foil-shielded twisted pairs.
