CCI’s Fiber Distribution Unit provides the means to coinvert RF input signal from the SXM Dual Band Exciter (DBE) into optical outputs that are used to distribute the SXM transmission to multipler Remote Fiber Units (RFU's). The FDU also provides bi-directional digital fiber connections to the individual RFU's to provide remote monitoring and control and reporting of real time signal quality metrics. Up to four optical fiber outputs are provided to distribute the SXM signal to multiple Remote Fiber Units.

CCI’s Remote Fiber Unit contains a Fiber to RF converter and pre-amplification and power amplification stages to elevate the SXM output to the desired level. An Automatic Leveling Control (ALC) loop adjusts the gain of the RFU to ensure a SXM High Band or Low Band output level no less than 17dB below the maximum composite WCS signal.
