Twisted-Pair Ethernet Cable-Type Connectivity

The following types of TPE cables can be connected to the 8-pin TPE connector:

For 10BASE-T applications, shielded twisted-pair (STP) cable:

Category 3 (STP-3, voice grade)

Category 4 (STP-4)

Category 5 (STP-5, data grade)

For 100BASE-T applications, shielded twisted-pair category 5 (STP-5, data grade) cable.
