Modulation in the host ports uses frequencies of up to 500 MHz to achieve 10Gbps transmission over copper twisted-pair cabling. This modulation requires suppression of both external and internal noise up to 500 MHz.
The 10GBASE-T ports on the switch support the following types of twisted-pair copper cables:
Category 7, shielded (100m)
Category 6A, shielded and unshielded (100m)
Category 6, shielded and unshielded (55m)
Category 5e, shielded and unshielded (55m)
