1Introduction
MA200 QX remote is a compact, modular, cellular indoor coverage remote solution for the MA2000 distributed antenna
systems (DAS).
It is a fiber fed, compact and scalable multi-service platform designed to complement the MA1000 and MA2000 supporting up
to four services (CELL, PCS, and AWS1/3).
All services are received from the headend, over an optic fiber pair, converted back to RF and distributed over a common
DAS antenna infrastructure.
Service support can be quickly added as needed by inserting card like modules into the chassis without any downtime or
additional cabling. In addition, two QX units can be cascaded to provide various combinations of SISO and MIMO services.
MA2000 QX remotes share a common equipment headend and element management system (EMS) with other remotes on
the MA1000/MA2000 platform. Management and configuration options are provided for each QX service module (i.e., RHM
and AO) and for the QX chassis fans via a web session to the SC-450 controller.
MA2000 QX
Figure 1-1
1.1 Key Features and Capabilities
The following benefits are achieved with the QX platform:
•Multiservice platform - supports up to four services: CELL850, PCS1900 and AWS3 services in various configurations.
•Multi-operator optimized platform - services from a number of operators can be supported by the same chassis or by
different units and distributed over a common DAS antenna infrastructure.
•Optic fiber savings - all services routed to an QX unit are routed over a single optic fiber
•Modular design - seamless service upgrades – simply insert a module in the MA2000 QX and configure
•Scalable MIMO upgrades - upgrade any or all services from SISO to MIMO by cascading another QX unit
•Small footprint - 3 U height rack; 4 U height rack including SCU-F unit
•Simple maintenance - All connections and status LEDs located on front panel; Modular, hot-swap, field replaceable
service modules, including fan modules
•Web management - web management via the SC-450 controller

Corning Optical Communications User Manual I CMA-255-AEN I Page 12
1.2 System Architecture
MA2000 QX compliments the MA2000 DAS solution and coexists alongside other MA1K and MA2K remotes, sharing a
common headend. The QX remote unit provides coverage for up to four RF services over a common fiber/coax antenna
infrastructure. The QX is installed at the remote end on floor level and operates in conjunction with the service combiner unit
(SCU-F) which combines the service signals and distributes them to up to four broadband antennas.
Headend:
At the headend MA2000 elements provide interface to the wireless service provider’s network, condition the signals and
convert them to optical signals for transportation over fiber optics towards the remote ends.
•Radio Interface Unit (RIU) - the RIU conditions and custom tunes the RF downlink signals from an operator’s signal
source (BTS or BDA) to ensure a constant RF level. In the uplink, the signal (at the required level) is routed back to the
operator’s signal source.
•Base Unit (BU) – RF-to-optic converter unit – The BU is a wideband unit that convert the RF downlink signals from the
RIU into optical signals for routing over single or multi-mode fiber optic cabling (SM/MM) to/from the QX units located at
the remote locations up to 2 km away.
•System Controller (SC-450) - the system controller enables centralized remote management and control of MA2000
elements. This unit connects directly to the RIU and BU and allows management of these as well as their hosted
elements (e.g. QX) via a controller web session.
Remote End:
At the remote end, the optical signal is reconverted to RF, filtered, amplified to the appropriate level, combined with other
signals and distributed over the broadband antenna infrastructure. The QX unit is installed, along with the SCU-F. The QX
system remote end consists of the following elements:
•MA2000 QX - each QX unit provides coverage for four RF services (e.g. CELL, PCS, LTE 700 MHz, and AWS3) via two
types of service dedicated internal modules (RHM and AO). Each of these modules is monitored via the controller as an
independent unit:
•Remote Hub Module (RHM): The RHM is a service-specific module, supporting two services, that performs optical to
RF conversion of signals received from the BU. Signals are automatically filtered and amplified for transport over
broadband coax cable to a passive antenna. Uplink signals from the antennas are then converted to optical signals
before being transmitted back to the BU.
•Add-On Module (AO): The AO is a single service module coupled with an RHM to deliver an additional service at a
lower incremental cost. The AO receives RF signal from the RHM and amplifies it to transport across the broadband
coax.
•Service Combiner Unit (SCU-F): The SCU-F is a passive unit that can combine service signals from up to two fully
loaded QX units and distributes the combined signals over broadband antennas.
Note: The QX can be used with any flavor of SCU (i.e. SCU-F, SCU-FT, SCU-4, SCU-8).

Corning Optical Communications User Manual I CMA-255-AEN I Page 13
Figure 1-2 sows an example of an MA2000 QX deployment including two QX remote units (quad-band and tri-band). The QX
receives RF over optic service signals from the headend, reconverts the signals to RF over copper, adjusts them to the
required level and outputs each service to dedicated interfaces. The signals are combined by the SCU-F (along with services
from other QX units) and distributed over a common distributed antenna system infrastructure.
In the uplink, cellular service signals received at the DAS are separated by the SCU-F and routed to their dedicated QX ports.
The signals are then converted to optic and forwarded to the head-end for reconversion to RF and distribution to the relevant
BTS or BDA systems.
Note: Third party equipment is sold separately (i.e., cabling, antennas).

2Installation Guidelines
2.1 Infrastructure Preparation
This following installation rules are based on the assumption that site survey and installation planning (including power
requirements) have been completed.
2.2 Installation Requirements
The infrastructure preparation consists of two main phases:
Floor Planning: Planning the distribution of the antennas on each floor to provide the required coverage.
Telecom Closet Planning: Planning the layout of the devices and cables in the telecom closet or shaft.
2.3 Coaxial Cable Connections
2.3.1 General Cable Installation Procedures
Observe the general cable installation procedures that meet with the building codes in your area. The building code requires
that all cabling be installed above ceiling level (where applicable). The length of cable from the risers to each antenna must
be concealed above the ceiling.
The cable must be properly supported and maintained straight using tie-wraps, cable trays and clamps or hangers every 10
feet (where practical above ceiling level). Where this is not practical, the following should be observed:
•The minimum bending radius of 7-in is required for the supplied ½-in coax cable.
•Cable that is kinked or has a bending radius smaller than 7-in must be replaced.
•Cable runs that span less than two floors should be secured to suitably located mechanical structures.
•The cables should be supported only from the building structure.

2.3.2 RF Rules
•When using the MA2000 system in an environment in which other indoor coverage systems are installed, it is
recommended (where possible) that the antennas are placed at least two meters apart
•When bending coax cables, verify that the bending radius does not exceed the coax specifications.
•Use wideband antennas supporting a range of 800 MHz to 2500 MHz
•Use a VSWR meter (i.e. Site Master or equivalent) for checking coax cables, including the antennas. (< 2). The VSWR
must be measured prior to terminating the RUs in the remote communication rooms
•Terminate all unused SCU ports with a 50 ohm load
2.3.3 Coax Cable Lengths and Losses
Use coax ½”, 50 ohm, male-to-male QMA type, for connecting to SCU broadband antenna ports.
Note: The required distance between the antennas (installed in the ceiling) depends on the infrastructure and calculated path-
loss. For example, if there is free space-loss between the antennas, a minimum distance of 100 ft is required; if there are
partitions (loss) between the antennas, a distance of less than 100 ft between them is allowed.

2.4 Fiber Optic Rules
•Either single mode or multimode fiber can be used with QX products.
•Only Multimode fiber, 50/125 or 62.5/125um complying with ANSI/TIA/EIA-568-B series, EN50173-1 or ISO/IEC 11801
can be used. The fiber length can be up to 300 meters assuming the following qualifications:
•All fiber in a given length of fiber must be of the same core diameter.
•All Bulkhead adapters must be Single mode SC APC (Green) adapters.
•All terminations cross connections or patches must be direct fusion splice or the specified patch cords listed below.

•Use only 8-degree SC APC connectors (green color).
•Use only fusion splice for connecting two fibers.
•Use minimum splicing/connectors to achieve minimum losses on the fibers (<0.5 dB).
•Use precaution while installing, bending, or connecting fiber optic cables:
•Fiber optic cable is sensitive to excessive pulling, bending and crushing forces. Consult the cable specification sheet
for the cable you are installing.
•Do not bend cable more sharply than the minimum recommended bend radius.
•Do not apply more pulling force to the cable than specified.
•Do not crush the cable or allow it to kink. Doing so may cause damage that can alter the transmission characteristics
of the cable. The cable may have to be replaced.
•Use an optical power meter and light source for checking the fiber optic cables.
•Make sure the environment is clean while connecting/splicing fiber optic cables.
•All fiber optic connectors should be cleaned prior to connecting to the system
•Fiber connector protective caps should be installed on all non-terminated fibers and removed just before they are
terminated.
•Check the Fiber Optic connections.
•Pay special attention while connecting the SC APC connectors - ensure that you hear a “click”, indicating a secure
connection
•Never look directly into the end of a fiber that may be carrying laser light. Laser light can be invisible and can damage
your eyes.
