INTRODUCTION
GX products offer scalable, cost-effective 40 W (46 dBm)
high-power remote outdoor coverage solutions for Corning
distributed antenna systems (DAS).
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.
GX is a fiber-fed, dual-band, multioperator remote designed to
complement lower power, standard remotes. GX can also be
installed as a dedicated solution for new sites, providing
complete RF coverage in large open indoor, tunnel, and
adjacent outdoor spaces.
Using low-loss fiber optic cabling, GX remote units can
distribute multiple BTS signal sources for 2.3 GHz and 2.5 GHz
TDD to multiple remote locations between 2 to 15 km from the
headend to remotes. GX efficiently supports all operator
modulations with linear MCPA (multicarrier power amplifier)
up to 40 W.
GX remotes offer high RF power coverage capabilities with
compact design for added spaces savings and
weather-resistant enclosures to fit various site needs..

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. The conditioned MIMO1 and MIMO2 signals are then
transferred via the interface box* (IFB) and routed through the
optical central hub (OCH)
†
optical modules. For the TDD band,
an integrated IF clock module (pilot), installed in the IFB enables
transmitting the converged wideband RF/IF and pilot signals
through the interface box to the OCH. The OCH converts the RF
signal to an optical signal for transport over low-loss fiber
cabling to/from multiple GX remotes, where they are converted
to high-level RF signals. The GX includes an internal combiner
so that both WCS and 2.5 GHz TDD bands services are
transmitted via a single output port (SISO) or two for MIMO.
An external low-loss combiner is used to combine the
dual-band GX with the quad-band GX to support six bands
services on a single output port.
The GX remotes (and OCH) are managed and controlled via the
headend control module (HCM)
‡
installed in the headend
chassis, enabling local and remote management and providing
single-source, centralized common headend controls of all
installed elements.
*Each interface box supports connections to up to two HEUs or integrated
headend units (IHUs) via ERFCv2 cables.
†RF connections between the interface box and the OCH are performed using
QMA-to-QMA cables (accessory kit part number: AK-RIU4-OCH-CABLES).
‡In deployments with the ONE solution, GX remotes require an SC-450 interfacing
between the OCH and HCM for management capabilities.
Notes:
•
Only extended radio interface modules (RIMe) support
GX-E17E85P19L70-40-AC and GX-E17E85P19L70-40-DC. See
ordering information in this document for relevant part
numbers.
•
The dual-band GX with WCS and 2.5 GHz TDD support is
supported by SC-450 v7.6 and higher and ONE
v3.3 and higher.

Corning Optical Communications User Manual | CMA-601-AEN | Page 10
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/2.5 GHz TDD
(dual-band) remote alongside a GX quad-band remote where it
supports connections to two OCH optical modules per service
group (i.e., three OCH-8 or six OCH-4 units).
Block Diagram of IFB System Description | Figure 1.3
1.2.3 GX Deployed with MA1K/MA2K
Platform
Figure 1.4 illustrates a GX dual-band remote MIMO scenario
deployed with an MA1000/2000 headend alongside two GX
quad-band remotes providing MIMO coverage for the
CELL/ESMR, PCS, EAWS, and 700 LTE bands..
Note: GX quad-band models GX-E17E85P19L70-40-AC and
GX-E17E85P19L70-40-DC do not support coexistence with other GX
models. The quad-band services must be routed through separate
RF paths (i.e., different RIU-12 sector and optical module).
The MIMO1 and MIMO2 services are conditioned via two
independent sectors in the RIU-12 units, ensuring a constant RF
level for each MIMO stream. The conditioned MIMO1 and
MIMO2 signals are routed through separate optical modules in
the OCH. Each optical module converts the RF signal to an
optical signal for transport over low-loss fiber cabling to/from
connected GX remote, where they are converted to high-level
RF signals.
The GX dual-band remote includes an internal combiner so that
both WCS and 2.5 GHz TDD bands services are transmitted via a
single output port (SISO) or two for MIMO. In addition, an
external low-loss combiner is used to combine the dual-band
GX with the quad-band GX to support six bands services on a
single output port.

Example of GX Dual-Band alongside GX Quad-Band Remotes in an MA2K System Deployment | Figure 1.4
Corning Optical Communications User Manual | CMA-601-AEN | Page 12
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.
The OCH is connected directly to the SC-450 controller so that a
single management connection enables management and
monitoring capabilities for the GX and host OCH
.
Figure 1.5 and Figure 1.6 show examples of GX management
screens in the SC-450 and HCM management web GUI
applications.

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.
•
The system delay of the optical system must be taken into
consideration when there are neighboring BTS sites
overlapping in coverage.
•
In the MIMO scenario, one MIMO remote unit shall use two
pairs of optic fiber to ensure avoiding system delay.
2.1.1 Installation Location
Mounting surface shall be capable of supporting the weight of
the equipment.
In order to avoid electromagnetic interference, a proper
mounting location must be selected to minimize interference
from electromagnetic sources such as large electrical
equipment.
2.1.2 Environmental
Humidity has an adverse effect on the reliability of the
equipment. It is recommended to install the equipment in
locations having stable temperature and unrestricted airflow.
The installation location for the system should be well
ventilated. The equipment has been designed to operate at the
temperature range and humidity level as stated in the product
specifications at temperatures ranging from -40~70 degrees
Celsius and a relative humidity of maximum 95 percent.
2.1.3 Powering
•
The power supply unit provides power to all modules within
the equipment. Depending on the product variant, it is
recommended that the PSU operates on a dedicated AC
circuit breaker or fused circuit.
•
Pluggable equipment — the socket outlet should be installed
near the equipment and be accessible
2.1.4 Grounding Requirement
Verify that the equipment has been well grounded. This
includes GX dual-band unit, external combiner, antennas, and
all cables connected to the system. For GX grounding, use
provided copper wire grounding cable. Ensure lightning
protection for the antennas is properly grounded.
2.1.5 Cable Routing
Ensure all cables, e.g., power cable, feeder cable, optic fiber,
commissioning cable, connecting are properly routed (use drip
loops) and secured so that they are not damaged.
2.1.6 Manual Handling
During transportation and installation, take necessary handling
precautions to avoid potential physical injury to the installation
personnel and the equipment.
2.2 Installation Requirements
•
Working space available for installation and maintenance for

•
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.
Corning Optical Communications User Manual | CMA-601-AEN | Page 18
•
Do not locate the equipment near large transformers or
motors that may cause electromagnetic interference.
•
Reduce signal loss in feeder cable by minimizing the length
and number of RF connections.
•
Ensure the equipment will be operated within the stated
environment (refer to datasheet).
•
Where appropriate, confirm availability of suitably
terminated grade of RF and optical fiber.
•
Observe handling of all cables to prevent damage.
2.3 Fiber Optic Rules
ATTENTION!
•
Please also refer to the laser safety section in the document
preface material.
•
Fiber optic cables require proper handling. Do not stretch,
puncture, or crush the fiber cable(s) with staples, heavy
equipment, doors, etc.
•
Always maintain the minimum bend-radius specified by the
cable manufacturer. The minimum bend radius is usually ten
times the cable's outer diameter. In the case of single optical
fiber that is not in a cable, the minimum bending radius to be
observed is 30 mm.
•
Wavelength division multiplexing (WDM) units require
single-mode fiber.
•
Use minimum splicing/connectors to achieve minimum
losses on the fibers.
•
Use precaution while installing, bending, or connecting fiber
optic cables.
•
Use an optical power meter and optical time domain
reflectometer (OTDR) for checking the fiber optic cables.
•
Make sure the environment is clean while
connecting/splicing fiber optic cables.
•
All fiber optic connections should be cleaned prior to
attaching to termination points using a dry cleaning device
(e.g., Cletop or equivalent).
•
Fiber connector protective caps should be installed on all
non-terminated fibers and removed just before they are
terminated.
•
Check the fiber optic connections.
