CONFIDENTIAL D-620610-0-20 Rev F
* Exceeding the distance of copper-clad cable will result in the attached RAU becoming non-functional. If
the distance of a cable run is at its maximum and is of concern, TE recommends the use of solid copper
cable to ensure successful operation.
5.2 Remote Access Unit Connectors
5.2.1 50 Ohm Type-N Connector
The RAU has one female type-N connector. The connector is a duplexed RF
input/output port that connects to a standard 50 passive antenna using coaxial cable.
5.2.2 75 Ohm Type-F Connector
The RAU has one type-F female connector that connects it to a Fusion Hub using
CATV 75 Ohm cable. Use RG-59, 6, or 11 solid copper center conductor cables.
