1 DESCRIPTION
Software Defined Radio (SDR), refers to wireless communication in which the transmitter
modulation is generated and receiver demodulation recovered by software operating on a
computer. To select the desired modulation and demodulation type, configuration programs
must be run by microcomputers controlling the transmitter and receiver.
The most significant asset of SDR is versatility. Wireless systems employ protocols that vary
from one service to another. Even in the same type of service, for example wireless fax, the
Warning: To prevent electrical shock, never install equipment in a wet location or during a
lightning storm. When installing or modifying telephone lines, disconnect lines at the network
interface before working with uninsulated lines or terminals. Disconnect all power feeds before
working with uninsulated lines or terminals.
Danger: This equipment uses a Class 1 Laser according to FDA/CDRH rules. Laser radiation
can seriously damage the retina of the eye. Do not look into the ends of any optical fiber. Do not
look directly into the optical transceiver of any digital unit or exposure to laser radiation may
result. An optical power meter should be used to verify active fibers. A protective cap or hood
MUST be immediately placed over any radiating transceiver or optical fiber connector to avoid
the potential of dangerous amounts of radiation exposure. This practice also prevents dirt
particles from entering the transceiver or connector.
Warning: This equipment generates, uses, and can radiate radio frequency energy and if not
installed and used in accordance with the instruction manual, may cause interference to radio
communications. It has been tested and found to comply with limits for a Class B digital device
pursuant to Subpart B of Part 15 of FCC Rules, which are designed to provide reasonable
protection against such interference when operated in a residential environment. If interference
to TV and radio reception does occur relocate or reorient the antenna of the affected radio or TV.
This equipment does not exceed Class B limits for radio emission for digital apparatus, set out
in the radio interference regulation of the authorization methods of Industry Canada.
This equipment complies with the applicable sections of RSS-131. The term “IC:” before the
radio certification number only signifies that Industry Canada Technical Specifications were met.
This product conforms to all applicable standards of 21 CFR 1040.

protocol often differs from country to country. A single SDR set with an all-inclusive software
repertoire can be used in any mode, anywhere in the world. Changing the service type, the
mode, and/or the modulation protocol involves simply selecting and launching the requisite
computer program. A SDR PCIx Host Card is shown in Figure 1.
Figure 1. SDR PCIx Host Card
Software Defined Radio (SDR) allows a single device to adapt to different communications
environments and systems by selecting the most appropriate protocol and frequency needed for
a link. One device may work with a wireless local area network protocol in the city, and then be
reconfigured to work with terrestrial and satellite protocols to deliver broadband applications to
rural and remote areas.
SDR works much like desktop computing, where a single hardware platform carries out many
functions based on the software applications loaded. SDR uses software to perform radio-signal

3 SDR PCIx HOST CARD CABLING
3.1 Optical and Electrical Connections
Optical and electrical connections with the remote unit and GPS are supported by four optical
and two electrical ports. The electrical interface to the GPS is through coaxial cable connections
using two type SubMiniature version A (SMA) female connectors. Single-mode fiber provides
the optical connection between the SDR PCIx Host Card and Remote Units. The forward and
reverse ports provide the optical communication channel in a non-diversity system. The REV
DIV port provides receive optics for a diversity system. Each optical port uses a small form
factor LC-type optical transceiver. Modular optical transceivers are field replaceable and
available separately.
3.2 Coax Cabling
3.2.1 Coaxial Cable Requirements
The
SDR
PCIx Host card is equipped with
SMA
-type female 50-Ohm connectors for connecting
the timing input/output signals from the GPS unit. High performance, flexible, low loss 50-ohm
coaxial communications cable (RG316 or equivalent) should be used for all coaxial connections.
3.2.2 Coaxial Cable Connections
The RF interface between SDR PCIx Host card and the GPS is supported through a pair of type
SMA female connectors mounted on the DHU front panel. One connector provides the coaxial
cable connection for the REF (10 MHz sine wave) signal. The other connector provides the
coaxial cable connection for the PPS (1 pulse per second) signal. Use the following procedure to
install the coaxial cables and connect them to the DHU:
1. Obtain the required lengths of high performance, flexible, low loss 50-ohm coaxial
communications cable (RG316 or equivalent) for all coaxial connections.
ADCP-75-163SDR • Issue 1 • September 2004
Page 8

2. Route the timing input/output coaxial cables (if not already routed) between the SDR PCIx
Host card and the GPS interface device (per system design) and cut to the required length.
Allow sufficient slack for dressing and organizing cables at the SDR PCIx Host card.
3. Terminate each cable end with the appropriate male connector following the connector
supplier’s recommendations.
4. Connect the cables to the connectors on the SDR PCIx Host card as shown in Figure 2.
Figure 2. Coax Connectors
5. Dress and secure cables at the SDR PCIx Host card per standard industry practice.
6. Connect the coax cables to GPS receiver as specified in instructions provided with that unit.
3.3 Optical Cabling
3.3.1 Optical Options and Requirements
Each SDR PCIx Host Card and its associated remote (radio head) unit is connected over a pair
of optical fibers. One fiber transports the forward path optical signal and the other fiber
transports the reverse path optical signal. When diversity is used a third fiber is connected to the
REV DIV port. 9/125 single-mode optical fiber is used for the optical transport connection.
With 9/125 single-mode fiber, the optical path may be up to 10 kilometers in length. Optical

fibers must be terminated with duplex LC connectors for connection with the SDR card.
Remote unit has SC connectors.
The maximum length of the optical links is dependent on the loss specifications of the optical
fiber and the losses imposed by the various connectors and splices. The system provides an
optical budget of 20dB (typical) when used with 9/125 single-mode fiber.
Whenever possible, use conduit or a guideway to route optical fibers between the SDR PCIx
Host card and the remote (radio head) unit. Avoid routing optical fibers through ladder type
cable racks or troughs that do not provide sufficient support to limit bending or prevent
accidental damage. Tie-wrapping is not recommended as a means of securing fiber optic cables.
Provide sufficient slack at each unit for connecting each fiber to the required port. Fibers may
be pre-terminated or terminated on-site using field-installable LC type connectors.
3.3.2 Optical Connections
The optical interface between the SDR PCIx Host card and the remote (radio head) unit is
supported by two optical ports. Each of the SDR PCIx Host card optical ports provides a duplex
LC-type optical transceiver which is mounted on the SDR PCIx Host card front. The remote
(radio head) unit has SC connectors.
The FWD and REV ports provide forward and reverse optical communications channels in a
non-diversity system. The REV DIV port provides receive optics for a diversity system See
Table 1 for transceiver port designations. See Figure 3 for port designations.
Note: To insure that all optical connectors and transceivers remain dust-free during
installation, leave all dust caps and dust protectors in place until directed to remove them
for connection.

Danger: This equipment uses a Class 1 Laser according to FDA/CDRH rules. Laser radiation
can seriously damage the retina of the eye. Do not look into the ends of any optical fiber. Do not
look directly into the optical transceiver of any digital unit or exposure to laser radiation may
result. An optical power meter should be used to verify active fibers. A protective cap or hood
MUST be immediately placed over any radiating transceiver or optical fiber connector to avoid
the potential of dangerous amounts of radiation exposure. This practice also prevents dirt
particles from entering the transceiver or connector.
