TPO - Computer Definition
(Twisted Pair Only) The use of twisted pair wire when other options are available. For example, a TPO suffix at the end of an earlier 3com Ethernet adapter model numbers indicated the card had only an RJ45 connector. TP meant RJ45 and AUI connectors, TPC was RJ45 and BNC, and COMBO cards provided all three. See 10Base2 and 10Base5.
