Warnings and Admonishments There may be situations, particularly for workplace environments near high-powered RF sources, where recommended limits for safe exposure of human beings to RF energy could be exceeded. In such cases, restrictive measures or actions may be necessary to ensure the safe use of RF energy. The equipment has been designed and constructed to prevent, as far as reasonably, practicable danger.
Compliance with RF safety requirements: Corning products have no inherent significant RF radiation. The RF level on the downlink is very low at the downlink ports. Therefore, there is no dangerous RF radiation when the antenna is not connected. Laser Safety Fiber optic ports of the GX system emit invisible laser radiation at the 1310/1550 nm wavelength window. The laser apertures /outputs are the green SC/APC Bulkhead adapters located on the front panel of the equipment.

1 Introduction GX quad-band remote (“GX”) offers a cost-effective 40 W (46 dBm) high power remote outdoor coverage solution for MA2000 distributed antenna systems (DAS). GX is a fiber-fed, multi-frequency, multi-operator remote designed to complement the MA2000 lower power, standard remotes. GX can also be installed as a dedicated solution for new sites, providing complete RF coverage options for open indoor, tunnel and adjacent outdoor spaces.
Key Features and Capabilities Multi-Frequency/Multi-Service RF Transport Platform: Accommodates CDMA, GSM, UMTS, HSPA, LTE, EDGE, EVDO technologies and more. Four model-dependent bands per enclosure Cost-Effective Higher Power: Optimizes and reduces the number of antennas required to cover open and outdoor areas by offering 46 dBm composite power per frequency band Operator-Grade Operation: Advanced signal handling and management ensures operator-grade performance.
1.1 System Architecture GX provides a complete solution consisting of GX-Quad remote units at the remote locations, and head end elements, which are shared with any existing or new MA1000/MA2000 deployment. GX consists of a uniquely designed, non-obtrusive unit that includes all of the required RF, fiber optic and power interfaces. All mobile services are distributed through service/band dedicated RF connection ports over antennas installed at the remote locations.
1.1.2 MIMO Scenario Figure 1-3 illustrates a MIMO scenario supported by two GX Quad-Band units. In MIMO installations each MIMO stream is supported by a single GX unit. The MIMO1 and MIMO2 services are conditioned via two independent sectors in the RIU-12 (i.e., SectorA and SectorB) and routed through separate optical modules in the OCH.
1.1.3 Signal Path In the downlink path, combined RF signals (from up to four supported services) from the radio interface unit (RIU) are converted into optical signals by the OCH. The optical signals are then transmitted to the GX at the remote site via optical fiber. The signals are filtered and amplified at the GX and transmitted through the service specific output ports to the broadband antennas. In the uplink path, GX converts the RF signals transmitted from the service antennas into optical signals.
1.2 System Monitoring and Management The GX-Quad Remote Unit is centrally managed via the MobileAccess SC-450 Controller. Note: The GX Quad-band solution is supported by SC-450 v5.4 and higher. The GX remote is not connected directly to the controller; it is connected to the OCH-GX element (that is connected to the controller). Thus, the controller monitors views and manages the GX via the OCH-GX, hosting the GX unit. The following shows the Configuration tab of the selected GX unit.
1.3 GX Quad-Band Remote Interfaces All of the GX interfaces (except for the power connector) are located externally on the underside of the unit (facing down when unit is mounted). The unit interfaces include the RF, power, optical link and external alarms connections. The power connector is located in a separate side panel. Figure 1-6. Example of GX Quad-Band Remote (AC) Interfaces – Side Panel (Left) and Underside (Right) Table 1-1 and Table 1-2 provide descriptions of the GX-Quad connectors and LEDs.
Interface Description EAWS CPL -50 dB Coupler port EAWS 50 dB coupling 850 MHz CPL -50 dB Coupler port 850 MHz 50 dB coupling 700 MHz CPL -50 dB Coupler port 700 MHz 50 dB coupling FILTER_ OUT/ FILTER_ IN* Connections to external filter – only relevant if External Filter (ordered separately) is installed on GX-Quad Table 1-1. GX Interface Descriptions LED Description RUN Green – power on ALM Off – normal operation Red - fault COMM.
1.4 External Multiplexer (optional) Note: The external combiner is optional and ordered separately (P/N: AK-GX-ECPL-COMB). The 4x1 external multiplexer filters and combines the service specific RF signals received from the GX and transmits the converged input signals through a single output port to the broadband service antenna.
2 Installation Guidelines This chapter provides the general guidelines for installing the GX Quad-band Remote Unit and includes information such as site considerations and installation requirements. 2.1 Site Considerations The distance between the GX service antenna and the coverage area should correspond to line of sight (LOS) requirements for maximum coverage area. The maximum fiber path loss is 6 dB.
2.2 Installation Requirements Working space available for installation and maintenance for each mounting arrangement. Ensure unrestricted airflow. Ensure grounding connector is within reach of the ground wire. Ensure a power source is within reach of the power cord and the power source has sufficient capacity. Where appropriate, ensure unused RF connectors are terminated. Do not locate the equipment near large transformers or motors that may cause electromagnetic interference.
