Remote Fiber Unit | SER-RFU-2300 | |||
|
Overview
The 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. Technical Description: The CCI Fiber IP Repeater is a cost effective and easy to implement solution to provide high power distribution of SXM LB and HB transmission over the existing AT&T network. CCI’s Fiber Repeater is specifically designed to work with the SXM Dual Band Exciter (DBE) which accepts both High Band and Low Band UDP Stream inputs. |
Warning This is NOT a CONSUMER device. It is designed for installation by FCC LICENSEES and QUALIFIED INSTALLERS. You MUST have an FCC LICENSE or express consent of an FCC Licensee to operate this device. Unauthorized use may result in significant forfeiture penalties, including penalties in excess of $100,000 for each continuing violation.
