FCC Antenna Requirements
The user must assure that the installation meets FCC RF exposure limits. Minimum distance
between any person and the operating antenna must be 24 inches or 60 cm. The antenna must be
mounted on a stable, permanent structure.
Maximum ERP is 5 watts per FCC regulations per rule part 90.219(e)(1). The FCC licensed and
qualified installer user must calculate the total transmitted power, taking into account the losses of
the cables and splitters etc, plus the gain of the antenna to assure compliance with the maximum
exposure regulation.
Lightening protection is required on all antennas as loss or damage as a result of lightening is not
covered by the warranty. Antennas must be connected prior to turning up power to the unit.

Frequency Bands of Operation and RF output power control
The authorized bands of use include:
> 763-775 –793-805 MHz
> 758 -768 –788-798 MHz
> 806-824 –851-869 MHz
> 450-512 MHz
> 150-174 MHz
> 896-941 MHz
The plug-in cards determine the frequency transmitted. The manufacturer factory-sets the
operating bands for each plug-in card. Each card can accommodate frequencies across the entire
band or more. The operating bands can not be modified by the user. Consult the manufacturers
data sheet and this operating manual to confirm proper operation. RF Output is controlled
automatically by an ALC (automatic level control) circuit within the cards. The user can not set the
output power to exceed the FCC limits. The user can set the output power lower than the designed
maximum using the software supplied by the manufacture.

Fiber DAS Option: Model SAFE-1020 & SAFE-1015
Connect all units with power. Single-mode Fiber Connections are required for the fiber DAS option.
Power up the Head-End Unit and confirm the frequencies are set properly. See below. The
frequencies should have been programmed at the factory, but the installer must always confirm the
correct settings once the equipment is in the field. In a fiber DAS, power up and connect the
Remotes.
Setting up the Head-End Off-Air Unit
The SAFE-1000 Head-end sets up the same way regardless if it is a BDA or fiber DAS.
The first step is to assure the individual channel frequencies are programmed properly.

The channel card is now programmed to pass 450.0000 MHz.
Proceed to program each card in the subrack.
Note: All the cards should have been programmed to the proper frequencies per order at the
factory. Nonetheless, the installer must confirm the proper settings.
The Head-End “Off-Air” Unit receives an input from its Off-Air antenna which is pointing to the
donor base-station site - or from other radio signal source.
Each Channel Card plug-in card of the SAFE-1010 Head-End Unit accepts a broadband signal from
the Off-Air Receiver Card and filters everything out except the single desired frequency. That
frequency is set via the terminal program shown above.
The acceptable RF input power range per card = -100dBm to -10 dBm. Internal Automatic Level
control will amplify (or attenuate) the signal so that it is at the appropriate level to drive the next
stage. The next stage is a power amplifier (in the BDA case) or a fiber optic transmitter (in the Fiber
DAS case).

RF Input Levels
Typical input range into the SAFE-1020 and SAFE-1030 Channelized Head-end unit is -95 to -
10dBm
Within this range the Safe-Com Head-end will automatically compensate and adjust the level for
optimal drive into the fiber distribution system.
A signal injected into the Head-end unit below -95dBm will not drive the
fiber DAS properly causing low CNR. The system will automatically squelch signal below -95dBm.
A signal much above -10dBm will generate distortion and
at very high power levels, > 0 dBm, may damage the equipment.

Card System
The Safe-Com DAS is a “Opto-channelized” system. This means the individual RF carriers are
transported independently, on a dedicated RF and optical path, minimizing the opportunity to
generate intermodulation. Each plug-in card on the down-link carries a single RF channel.
There are four types of cards:
> Downlink Cards –these cards carry the signal from the base station to the
remote units (and towards the mobile radio user) . Two types: HEDL: Head-End Downlink and RDL:
Remote Downlink.
> Uplink Cards –these cards carry the signal transmitted by the users mobile
radio, received at the remote unit and transported by fiber to the head-end and its connected
base-station. Two types: RUL: Remote UpLink and HEUL: Head-End UpLink
A short pigtail with an SC/APC connector on the plug-in cards provides the optical interface.
A 50 ohm SMB jack provides the RF interface. It is located on the front panel of each individual
plug-in card.

Connecting the fiber
The SAFE-1000 uses standard singlemode fiber to connect the head-end with the remote Units.
Up to four remote units can be used with each Head-end.
Multiple Head-ends can be added to expand the System.
SC/APC are the standard connectors used. They use an 8 degree polish angle.
The number of fibers required for each remote depends on the Fiber Configuration of your system.
The number of fiber connections inside the Head-end Unit depends on the Topology of your
system.
Inside the Head-end unit one will find up to eight green SC/APC adapter ports.
Topology –Star: Each Remote requires a dedicated home run connection directly back to the
Head-end
Star is the default topology.
Fiber Configuration –Dual: Each Remote uses 2 fibers. One for uplink and one for downlink
Number of fiber connectors at Head-End: Eight (8)
Number of fiber connectors at Remote: Two (2)
Topology - Star: Each Remote requires a Home run connection directly back to the Head-end
Fiber Configuration - Single: Each Remote uses 1 fiber. Uplink and Downlink are optically
multiplexed onto the same fiber strand.
Number of fiber connectors at Head-End: Four (4)
Number of fiber connectors at Remote: One (1)
Topology - Linear: The fiber hops from Head-end to each Remote in a linear daisy chain. No
need to run each Remote to the Head-end.
Fiber Configuration - Dual: Each Remote uses 2 fibers. One for uplink and one for downlink same
fiber strand.
Number of fiber connectors at Head-End: Two (2)
Number of fiber connectors at Remote: Four (4) except the last Remote which has one (2)

Linear Topology
Setting up the Remote Unit
The Remote Unit accepts bidirectional optical signals via single mode fibers from the Head-End
Unit.
It converts the optical signals to RF –radio frequency.
The RF port is connected to a distributed antenna system consisting of antennas, splitters and taps.
The Remote Unit monitors the incoming signal and assures proper levels so as to guarantee the
radiated emissions downlink do not exceed FCC limits.
The uplink path provides a fixed gain back-haul to the Head-end. The system monitors the
incoming RF signal (from the antenna) and attenuates when excessive signal is detected at the
uplink input port. This is to prevent damage to the internal circuitry. Excessive RF input (above -
10dBm) can damage the unit so care should be take not to key up radios or cellphone near the unit,
especially during installation process. Radios including cellphones should not be used in close
proximity to the units.

Installation
Installation - Wall-Mounting:
When mounting the Remote on the wall, it is critical to provide
spacers between the unit and the wall. A one inch space is
appropriate to allow for air flow.
Power is hardwired into the unit. The power applied is based on the
model number ordered. Consult the order number and the
company data sheet to confirm power type. Options include
120VAC, 12VDC, -48VDC.
RF cable selection is based on the RF connector requested .
Default type is a panel mounted 50ohm SMA female. Therefore the
RF cable required will be 50ohm SMA Male.
