Admonishments
Important safety admoni shmen ts are used throughou t thi s manual to warn of possi ble haza rds to
persons or equipment. An admonishment identifies a possible hazard and then explains what
may happen if the hazard is not avoided. The admonishments — in the form of Dangers,
Warnings, and Cautions — must be followed at all times. These warnings are flagged by use of
the triangular alert icon (seen below), and are listed in descending order of severity of injury or
damage and likelihood of occurrence.
Danger: Danger is used to indicate the presence of a hazard that will cause severe personal
injury, death, or substantial property damage if the hazard is not avoided.
Warning: Warning is used to indicate the presence of a hazard that can cause severe personal
injury, death, or substantial property damage if the hazard is not avoided.
Caution: Caution is used to indicate the presence of a hazard that will or can cause minor
personal injury or property damage if the hazard is not avoided.
General Safety Precautions
Caution: Elect ronic modules can be damage d by electrostatic di scharge (ESD). To prevent this,
take the following precautions:
• Wear an anti-static-discharge wrist strap while handling modules.
• Place modules in anti-static packing material when transporting or storing them.
Warn i ng : 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 dama ge the retina of the eye. Do not look int o the ends of any optical fi ber. 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 ov er a ny radiating transceiv er or optical fiber connec tor to avoid
the potential of dangerous amounts of radiation exposure. This practice also prevents dirt
particles from entering the transceiver or connector.

1DESCRIPTION
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
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
processing functions instead of using resistors, capacitors, feedback loops, or applicationspecific integrat ed cir cu its.
The SDR PCIx host card is installed in a server and cabled to the LRCS remote (radio head)
units and the GPS receiver. Power is provided by the server with configuration and software
management through the server communications interface. Communications with the network
is through the server and associated hardware and software.

3.1Optical and Electrical Connections
ADCP-75-163SDR • Issue 1 • Septembe r 2004
Optical and electrical connections with the remote unit and GPS are supported by four optical
and two electrical por ts. The el ectr ical i nterf ace to the GPS is th rough coa xia l cable connect ion s
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.

coaxial communications cable (RG316 or equivalent) should be used for all coaxial connections.
3.2.2Coaxial 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 conne ction for the PPS (1 pul se pe r second) sign al. Use the follo wing pr ocedur e to
install the coaxial cables and connect them to the DHU:

Each SDR P CIx Host Card and its asso cia ted r emot e (r adio head ) u nit is co nnec ted o ver a pa ir
of optical fibers. One fiber transports the forward path optical signal and the other fiber
transports the r eve rse path optical s ignal. When diversi ty i s used a third f ib er is connected to th e
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 sec uri ng f iber 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.
3.3.2Optical Connections
The optical interface between the SDR PCIx Host card and the remote (radio head) unit is
supported by two optic al ports. Each of the SDR PCI x Hos t c ar d optical ports provi des a d uplex
LC-type optical transceiver which is mounted on the SDR PCIx Host card front. The remote
(radio head) unit has SC connectors.
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.
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
Ta ble 1 for transceiver port designations. See Figure 3 for port designations.
Danger: This equipment uses a Class 1 Laser according to FDA/CDRH rules. Laser radiation
can seriously dama ge the retina of the eye. Do not look int o the ends of any optic al fi ber. 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 ov er a ny radiating transceiv er or optical fiber connec tor to avoid
the potential of dangerous amounts of radiation exposure. This practice also prevents dirt
particles from entering the transceiver or connector.
Use the following p roc edure to install t h e f or wa rd and reverse path op ti cal f ibers and to connec t
them to the SDR PCIx Host card:
1. Obtain the required lengths of single-mode fiber optic cable.
2. Route the fiber optic cable between the
SDR
PCIx Host card and the remote (radio head)
unit (if not already routed) and cut to required length. Allow sufficie nt slack for dressing and
organizing the cables at each unit. Maintain a minimum bend radius of 2 inches (50 mm).
Note:
Maximum path length for 9/125 single-mode fiber optical fiber is 10 km (32,808 ft.).
3. Terminate each optical fiber with a field-installable LC type fiber optic connector as
shown in Figure 4. Follow the instructions provided by the connector manufacturer for
installing the connector.
4. Test each fiber for optical loss.
5. Designate one of the fi be rs as the forward path fiber and th e othe r as the reverse path fibe r
and label both ends of each fiber with the path designation.
6. Use the plastic joiner provided with the LC connectors to join the SDR PCIx Host card
forward and reverse path connectors together (see Figure 4). Make sure the forward path
and reverse path connectors are oriented as shown.
7. Remove dust caps from the optical fiber connectors and the primary optical transceiver.
Note: Leave the dust cap in place on any unused optical transceiver.
8. Clean each connector (follow connector supplier’s recommendations) and then insert the
optical fiber connector pair into SDR PCIx Host card optical FWD/REV port.
9. Place the optical fibers within the cable guides provided on the cable management tray and
then dress and secure the fibers at the SDR PCIx Host card per standard industry practi ce.
