Ethernet cabling
Ethernet standards and cable lengths
All configurations require a copper Ethernet connection from the ODU (PSU port) to the PSU.
Advanced configurations may also require one or both of the following:
•
A copper Ethernet connection from the ODU (Aux port) to an auxiliary device.
•
An optical or copper Ethernet connection from the ODU (SFP port) to network terminating
equipment or a linked ODU.
specifies, for each type of PSU and power supply, the maximum permitted PSU drop
cable length.
specifies, for Aux and copper SFP interfaces, the Ethernet standards supported and
the maximum permitted drop cable lengths.
Note
For optical SFP interfaces, refer to
Ethernet standards supported and maximum permitted cable lengths.
