Note
For all system types the connection to the surface computer or IT infrastructure
from the Gemini Hub, Ethernet or VDSL adapter should be via a shielded Cat5e
cable fitted with an RJ45 connector. The 72V VDSL Adapter Unit can also be
used in applications where long length power and communications is desirable
