for installation by FCC LICENSEES and QUALIFIED INSTALLERS. You MUST have an FCC
LICENSE or express consent of an FCC Licensee to operate this device. You MUST register
Class B signal boosters (as defined in 47 CFR 90.219) online at www.fcc.gov/signal-
boosters/registration. Unauthorized use may result in significant forfeiture penalties, including
penalties in excess of $100,000 for each continuing violation. The installation procedure must
result in the signal booster complying with FCC requirements 90.219(d). In order to meet FCC
requirements 90.219(d), it may be necessary for the installer to reduce the UL and/or DL output
power for certain installations.
ATTENTION: This device complies with Part 15 of the FCC rules. Operation is subject
to the following two conditions: (1) this device may not cause harmful interference and
(2) this device must accept any interference received, including interference that may
cause undesired operation.
ATTENTION: FCC regulation mandate that the ERP of type B signal boosters should
not exceed 5W. This Digital Fiber DAS has a maximum DL composite output power of
5W (+37dBm) and UL composite output power of +24dBm, therefore the gain of the
DL antenna should be of 0dBi or less and maintain a minimum separation of 55 cm
from all persons, and the gain of the UL antenna should be 13dBi or less and maintain
a minimum separation of 55 cm from all persons.
IC Compliance
As per RSS 131 Issue 2:
Nominal passband gain: 80dB max
Nominal bandwidth: 90 kHz maximum for Canada market
Rated mean output power: +37dBm maximum in DL and +24dBm maximum in UL
Input and Output impedances: 50 ohms
The Manufacturer's rated output power of this equipment is for single carrier operation. For
situations when multiple carrier signals are present, the rating would have to be reduced by 3.5
dB, especially where the output signal is re-radiated and can cause interference to adjacent band
users. This power reduction is to be by means of input power or gain reduction and not by an
attenuator at the output of the device.
RF Exposure Statement for ISED: “This device complies with Health Canada’s Safety Code. The
installer of this device should ensure that RF radiation is not emitted in excess of the Health
Canada’s requirement. Information can be obtained at http://www.hc-sc.gc.ca/ewh-
semt/pubs/radiation/radio_guide-lignes_direct/index-eng.php”
UM-0840 3
The antenna/s used for this transmitter must be installed to provide a separation of at least 55 cm
in DL and 55 cm in UL from all persons and must not be collocated or operating in conjunction
with any other antenna or transmitter. Changes or modifications not expressly approved by the
party responsible for compliance could void the user’s authority to operate the equipment.
Selon RSS 131 Issue 2:
• Gain de bande passante nominal: 80dB max
• Bande passante nominale: 90kHz maximum pour le marché canadien
• Puissance nominale de sortie moyenne: + 37dBm maximum en DL et +24dBm maximum en UL.
• Impédances d'entrée et de sortie: 50 ohms
La puissance de sortie nominale du fabricant de cet équipement est pour le fonctionnement d'une

Product Description.
The UHF Low Fiplex Digital DAS has a modular structure that consists in two different modules in star
configuration, the Digital Master Unit model DH4L00-M (center of the star) and Digital Remote Unit model
DH4L37-R (legs of the star) that can operate in the UHF frequency range of 406-424MHz. Each one of the
different modules is enclosed in the same or equivalent case, therefore, product description and installing
instruction sections are valid for all of them.
The Fiplex Digital Master is a RF-to-Fiber and Fiber-to-RF conversion system. These conversions are done using
FPGA based Digital Signal Processing. It provides a connection to the Base Station and it centralises all the
connectivity of the DAS. It also provides the possibility to connect up to six Digital Remote Units.
The Digital Remote Unit, also is a RF-to-Fiber and Fiber-to-RF conversion system. These conversions are also
made using FPGA based Digital Signal Processing. It provides amplification to the RF signals needed to provide
signal amplification into the target area.
The Master and Remote Units is where the RF interfaces are located, the Master Unit has the “To Base” RF
Port, and the Remote Unit has the “To Mobile” RF Port.
The advantages of using digital signal transportation over fiber are to avoid the addition of the fiber analog noise
when it is used to transport analog signals. Along with this, the UL squelch of the Digital Remote Unit works not
only per channel but also per time slot, this makes the Fiplex Digital DAS solution unique by its outstanding
management of the UL noise.
The Fiplex Digital Master Unit also provides an access point to monitor and control all the system parameters
not only of the Digital Master Unit but also to each Digital Remote Unit connected on the system. This connection
can be done locally via USB or Web-Browser, or remotely using Ethernet (via SNMP protocol).
The DH4-L series are NFPA Ready orderable with AC or DC option. As optional it can have remote control via
Ethernet or via wireless modem.
The Digital Master Unit and the Digital Remote Units both have heavy duty IP67/NEMA4X cabinet for outdoor
usage, it is designed to be wall or pole mounted, however, to mount on standard 19” rack, a special mounting kit
can be supplied.
For more details refer to the product datasheet.

2.5 Interface with signal source
The interface with a Signal Source can be done in three different ways, depending on the availability of separated UL
and DL connectors.
In cases when the signal source will be picked from the air, there is no need to add a Signal Booster to feed the Digital
Master. The Digital Master in its standard configuration can pick the signals from the air just by connecting a donor
antenna to it.
In case when a BTS is used as a Signal Source and the coupling is made thru a Point Of Interconnection (POI). A POI,
can consist on a simple attenuator, duplexer, coupler or a combination of them and it is needed to accommodate the
DL level to the design requested level.

4.2 Starting Operation
BE SURE THAT “TO MOBILE” AND “TO BASE” PORTS ARE PROPERLY
LOADED EITHER WITH 50 OHMS DUMMY LOADS, OR RADIATING SYSTEM.
1. Turn on the repeater, connect computer to repeater through USB cable, and run Fiplex Control
Software. Check that all remote units are connected to the master through fiber optic checking link
status.
2. Enable channel filtering if needed and setup desired channel frequencies. If Fiplex Digital Fiber DAS is
used as channel selective, user has to know what frequencies are used in base station. Each channel
can be enabled independently. Channels not used can be showed / hidden using the “Show channels”
checkboxes. If remote units are on and connected through optical fiber, the corresponding uplink
frequencies will be automatically set, too.

UM-0840 25
5. Set up squelch settings. Controls are independent in UL (for each remote) and DL (master) bands.
Typical values for UL are between -110dBm and -100dBm for squelch threshold. For DL,
recommended value for squelch threshold is minimum level received in any active channel minus
10dB.
6. Setup desired filter bandwidth, depending on presence of adjacent channels. In principle,
recommended bandwidth filter is 90KHz due to its low delay, but if adjacent signal is detected, narrow
filters can be used. Fine gain can be set to equalize input signals.

6.3 Software description (Remote Unit)
While software connected to digital master allows configuration and monitoring of whole system, if
software is connected to remote unit, only parameters of this unit can be viewed / modified.
Then, status screen of remote unit only shows information regarding this unit:
UM-0840 37
Distribution and meaning of the controls contained in status page are very similar to single remote
frame of master status page, only optical frame is different due to only remote side of optical link is
monitored.
7 Local Software. Installation and troubleshooting
7.1 Installation
The following section will describe the steps to be followed in order to install and use the Fiplex
Control software with your Fiplex repeater.
1. Before connect USB cable between computer and repeater, run the
FiplexControlSoftware.msi File. Next screen will appear…
