4.1 Expansion Hub Overview

The Expansion Hub acts an interface between the Main Hub and the Remote Access

Unit(s) by converting optical signals to electrical signals and vice versa, as shown in

Figure 4-1. It also supplies control signals and DC power to operate the Remote

Access Unit(s) as well as passing status information from the RAUs to the Main Hub.

RAU

Downlink Path: The Expansion Hub receives downlink (Band 1, 2, and 3) optical signals from the Main Hub using fiber

optic cable. It converts the signals to electrical and sends them to up to eight Remote Access Units (RAUs) using CATV

cables. The Expansion Hub also receives configuration information from the Main Hub using the fiber optic cable and

relays it to the RAUs using CATV cable.

Uplink Path: The Expansion Hub receives uplink (Band 1, 2, and 3) IF signals from up to eight RAUs using CATV cables.

It converts the signals to optical and sends them to a Main Hub using fiber optic cable.

The Expansion Hub also receives RAU status information using CATV cable and sends it and its own status information to

the Main Hub using the fiber optic cable.
