1 1 INTRODUCTION GX products offer scalable, cost-effective 40 W (46 dBm) high-power remote outdoor coverage solutions for Corning distributed antenna systems (DAS). 1.1 Key Features and Capabilities GX remotes compliment both the MA1000/MA2000 platform and the Corning® optical network evolution (ONE™) solution, sharing a common equipment headend and element management system (EMS) with the other system remotes.
1.2 System Description 1.2.1 GX Dual-Band with Corning® Optical Network Evolution (ONE™) Solution Figure 1.2 illustrates a scenario including the dual-band GX MIMO remote supporting the WCS and 2.5 GHz TDD bands and two quad-band GX remote units each supporting ESMR/CELL, PCS, 700 LTE, and EAWS deployed with the Corning® optical network evolution (ONE™) solution. The MIMO1 and MIMO2 RF signals, received from the BTS, are conditioned by the headend unit (HEU), ensuring a constant RF level.
Example of GX Dual-Band with Quad-Band Remotes in Corning® Optical Network Evolution (ONE™) Deployment | Figure 1.
1.2.2 GX Interface Box (IFB) to ONE Headend The IFB is a combiner/splitter interface box which supports connections to two HEUs, combines the RF services and routes them through optical central hub (OCH) modules towards the GX remotes. The IFB includes an integrated intermediate frequency (IF) clock module for generating a 2970 MHz pilot signal required for synchronizing the TDD band. The IFB enables deploying a GX high-power WCS/2.
Example of GX Dual-Band alongside GX Quad-Band Remotes in an MA2K System Deployment | Figure 1.
1.3 System Monitoring and Management The GX dual-band remote unit is centrally managed via the SC-450 (v7.5 and higher) in MA1K/MA2K solutions and via the headend control module (HCM v3.2 and higher) when deployed with Corning® optical network evolution (ONE™) solutions*. *In Corning optical network evolution (ONE) solution deployments, the SC-450 is also required for the GX management. The GX remote management connection is performed via the optical central hub (OCH) to which it is physically connected.
Example of GX Dual-Band HCM Device Configuration Tab | Figure 1.6 1.4 GX Dual-Band 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, ground, optical link, and external alarms connections. The power connector (AC/DC) is located on the side panel. See Figure 1.7. Example of GX Dual-Band Remote Interfaces | Figure 1.

2 2 INSTALLATION GUIDELINES This chapter provides the general guidelines for installing the GX dual-band remote 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.
• Do not locate the equipment near large transformers or motors that may cause electromagnetic interference. • Wavelength division multiplexing (WDM) units require single-mode fiber. • Reduce signal loss in feeder cable by minimizing the length and number of RF connections. • Use minimum splicing/connectors to achieve minimum losses on the fibers. • Ensure the equipment will be operated within the stated environment (refer to datasheet).
3 3 SYSTEM INSTALLATION This chapter describes the installation procedure for the GX dual-band remote unit. 3.1 Selecting GX Dual-Band Mounting Location consideration that the unit must be mounted adjacent to the GX RF interfaces to facilitate the connections (DIN-DIN cables = 1.2 m). 3.2 Unpacking and Inspection Select the mounting location (wall/pole): Unpack and inspect the cartons as follows: • General surroundings 1.
