The eight type F connectors on the Expansion Hub are for the CATV cables used to 
transmit and receive signals to and from RAUs. Use only 75 ohm type F connectors 
on the CATV cable.

The CATV cable also delivers DC electrical power to the RAUs. The Expansion 
Hub’s DC voltage output is 54V DC nominal. A current limiting circuit protects the 
Hub if any port draws excessive power.

NOTE: For system performance, it is important to use only low loss solid cop-
per center conductor CATV cable with quality type F connectors that use captive 
centerpin connectors. Refer to Appendix A for approved cables and connectors.

This console port is only used by ADC manufacturing test purposes. DO NOT CON-
NECT ANYTHING TO IT.

Use a crossover Ethernet cable (PN-4069-ADB) to directly connect a laptop or PC to 
the RJ-45 female connector for local monitoring or configuring the Expansion Hub 
and associated RAUs using the AdminBrowser-EH resident software. The cable typi-
cally has a RJ-45 male connector on both ends. Refer to Appendix A.5 on page A-8 
for the cable pinout and the AdminBrowser manual.

The optical fiber uplink/downlink port transmits and receives optical signals between 
the Expansion Hub and the Main Hub using industry-standard SMF or MMF cable. 
The fiber port has two female SC/APC connectors:

This connector (labeled 

) is used to transmit (output) uplink optical signals 

to the Main Hub.

This connector (labeled 

) is used to receive (input) downlink optical sig-

nals from the Main Hub.

CAUTION: To avoid damaging the Expansion Hub’s fiber connector 
ports, use only SC/APC fiber cable connectors. Additionally, use only
