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.
A built-in ERMS module samples the RF output of the RFU and provides demodulation of the Terrestrial HB and LB waveforms. The ERMS provides health monitoring and alarming for the LB and HB SXM waveform. SXM Signal quality metrics such as RSSI, SINR, and RS Errors are reported to the FDU and can be monitored remotely.
The Remote Fiber Units also contain an integrated Diplexer that combines the SXM LB and HB outputs with the WCS A thru D blocks enabling the simultaneous transmission of the SXM signal with the AT&T WCS signal on a common output port.

 

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.
CCI’s Fiber IP Repeater consists of a single Fiber Distribution Unit (FDU) which supports up to four Remote Fiber Units (RFU’s) and contains an integrated RF to Fiber converter which converts the RF output from the DBE to four Fiber outputs that are used to distribute the SXM signals to multiple tower mounted Remote Fiber Units (RFU’s). The Remote Fiber Units (RFU’s) contain an integrated Fiber to RF converter and pre-amplification and power amplification for power transmission of the SXM LB and HB RF outputs over the AT&T network. The integrated WCS/SXM Diplexer eliminates the need for any other hardware on the tower or rooftop.
Remote Monitor and Control functionality of the Fiber IP Repeater is supported via Ethernet/SNMP. The NRCC can remotely access the FDU and its support peripherals. Local Maintenance and Control functionality is supported via the front panel. A second Ethernet port and a second set of dry contact relays are provided for alarm notification and to allow SXM to monitor the performance of the repeater system including real time monitoring of signal quality metrics of each remote repeater.

 

 

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.

Maintain a minimum separation distance from the Transmit Antenna to a person(s) of at least 60 cm. The qualified installer and/or end user of this RF device must control the exposure conditions to a minimum separation distance between the Transmit Antenna and any bystanders in order to ensure RF Exposure compliance.

This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instruction manual, may cause harmful interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful interference in which case the user will be required to correct the interference at own expense.
