Refer to Table 6, footnote 3, for ports that support 10GBase-T transceivers.
2
The JL563A 10GBase-T transceiver is limited to a 30m cable length.
3
For distances less than 20km, a 10dB attenuator must be used. For distances between 20km and 40km, a
5dB attenuator must be used. Attenuators can be purchased from most cable vendors.
