2.2 DRH Functions
This section describes the main functions of the DRH.
The Distributed Remote Head (DRH) performs the following functions:
Receives downlink baseband data from the DCU and sends uplink baseband data to the
DCU.
Receives RF signals from the antenna system, down-converts the signals to intermediate
frequency (IF) signals, amplifies the IF signals, and performs analog-to-digital
conversion. The transmit (TX) channel filters downlink signals, performs
digital-to-analog conversion, and up-converts RF signals to the TX band.
Multiplexes receive (RX) and TX signals on the RF channel, which enables these signals
to share the same antenna path. It also filters the RX and TX signals.
The DRH can be powered by the AC/DC power module. In this case, this DRH is called
AC DRH.
An DRH consists of a high-speed interface unit, signal processing unit, power amplifier, and
dual-duplexer. Figure 2-3 shows the logical structure of the DRH.

3.2 DRH PGND Cable
An DRH PGND cable connects a DRH and a ground bar, ensuring the proper grounding of
the DRH. The maximum length of a DRH PGND cable is 8 m (26.25 ft).
Exterior
A PGND cable is green or green and yellow with a cross-sectional area of 16 mm2 (0.025 in.2).
An OT terminal is installed at each end of the cable. Figure 3-1 shows a PGND cable.
Figure 3-1 PGND cable
(1) OT terminal (M6, 16 mm2 or 0.025 in.2)
(2) OT terminal (M8, 16 mm2 or 0.025 in.2)
If the customer prepares the PGND cable, a copper-core cable with a cross-sectional area of 16 mm2
(0.025 in.2) or larger is recommended.
One OT terminal must be added to each end of the PGND cable onsite.
You can determine the color of the cable and whether to use corresponding two-hole OT terminals
based on local regulations.
Figure 3-2 shows a two-hole OT terminal.
Figure 3-2 Two-hole OT terminal
3.3 DRH Power Cable
The DRH power cable is a -48 V DC shielded cable. It feeds -48 V DC power to a DRH. The
maximum length of a DRH power cable delivered with DRH s is 50 m (164.04 ft) by default.

The maximum length of power supply that a DRH power cable supports is 150 m (492.12 ft).
Contact Huawei engineers when a DRH power cable greater than 50 m (164.04 ft) is required.
If a power device provided by the customer is used, the recommended specification of the circuit
breaker on this power device is 15 A to 30 A.
Exterior
There are three types of DRH power cables in terms of cross-sectional areas: 5.3 mm2 (0.008
in.2) (10 AWG) and 8.2 mm2 (0.013 in.2) (8 AWG) complying with North American standards
and 6 mm2 (0.009 in.2) complying with European standards.
A tool-less female connector (pressfit type) needs to be added to one end of the DRH power
cable and a corresponding terminal needs to be added to the other end based on the
requirements of the connector on the external power device, as shown in Figure 3-3.

3.5 CPRI Fiber Optic Cable
CPRI fiber optic cables are classified into multimode fiber optic cables and single-mode fiber
optic cables. They transmit CPRI signals.
Multimode fiber optic cables connect the DCU and DRH or interconnect two DRHs. The
maximum length of the multimode fiber optic cable between the DCU and DRH is 150 m
(492.12 ft) and the multimode fiber optic cable between two DRHs has a fixed length of 10 m
(32.81 ft).
A single-mode fiber optic cable consists of the single-mode pigtail and trunk single-mode
fiber optic cable, and the single-mode pigtail and trunk single-mode fiber optic cable are
interconnected using the ODF. The maximum length of the single-mode pigtail is 20 m (65.62
ft) on DCU side and 70 m (229.66 ft) on DRH side.
The ODF and trunk single-mode fiber optic cable are provided by the customer and must comply
with the ITU-T G.652 standard.
The ODF is an outdoor transfer box for fiber optic cables, which interconnects the single-mode
pigtail and trunk single-mode fiber optic cable.
A multimode fiber optic cable and a single-mode fiber optic cable are connected to a multimode
optical module and a single-mode optical module, respectively.
Exterior
Multimode fiber optic cable: The multimode fiber optic cable has a DLC connector at each
end, as shown in Figure 3-5.
Figure 3-5 Multimode fiber optic cable
(1) DLC connector
(2) Breakout cable
(3) Label on the breakout cable
When a multimode fiber optic cable connects a DCU and a DRH, the breakout cable on the DCU
side is 0.34 m (1.12 ft) and the breakout cable on the DRH side is 0.03 m (0.098 ft).
When a multimode fiber optic cable connects two DRHs, the breakout cable on both sides is 0.03 m
(0.098 ft).
Figure 3-6 shows the connection of the multimode fiber optic cable between a DCU and a
DRH.

3.6 DRH RF Jumper
The 1/2" DRH RF jumper transmits and receives RF signals between a DRH and an antenna.
A fixed-length RF jumper used by an DRH is 2 m (6.56 ft), 3 m (9.84 ft), 4 m (13.12 ft), 6 m
(19.68 ft), or 10 m (32.81 ft). A variable-length RF jumper used by a DRH has a maximum
length of 10 m (32.81 ft).

When the distance between an DRH and an antenna is less than 10 m (32.81 ft), one end of the RF
jumper is connected to the ANT-TX/RXA or ANT-TX/RXB port at the bottom of the DRH, and the
other end is connected to the antenna.
When the distance between a DRH and an antenna is greater than 10 m (32.81 ft), one end of the RF
jumper is connected to a feeder, and the other end is connected to the antenna.
If the customer prepares the RF jumper, the length of the RF jumper should be as short as possible
and not exceed 2 m (6.56 ft.).
Exterior
An RF jumper has a DIN male connector at one end and a customized connector at the other
end.
Figure 3-9 shows an RF jumper with a DIN male connector at each end.

5.1 U.S.A Regulatory Compliance
This device complies with Part 15 of the FCC Rules. Operation is subject to the following two
conditions:
This device does not cause harmful interference.
This device must accept any interference received, including interference that may cause
undesired operation.
If this device is modified without authorization from Huawei, the device may no longer
comply with FCC requirements for Class B digital devices. In that a case, your right to use the
device may be limited by FCC regulations. Moreover, you may be required to correct any
interference to radio or television communications at your own expense.
This device has been tested and found to comply with the limits for a Class B digital device,
pursuant to Part 15 of the FCC rules. These limits are designed to provide reasonable
protection against harmful interference in a residential installation.
This device generates, uses and radiates radio frequency energy. If it is not installed and used
in accordance with the instructions, it may cause harmful interference to radio
communications.
However, there is no guarantee that interference will not occur in a particular installation. If
this device does cause harmful interference to radio or television reception, which can be
determined by turning the device off and on, the user may take one or more of the following
measures:
Reorient or relocate the receiving antenna.
Reinforce the separation between the device and receiver.
Connect the device into an outlet on a circuit different from that to which the receiver is
connected.
Consult the dealer or an experienced radio or TV technician for assistance.
This equipment complies with FCC RF radiation exposure limits set forth for an uncontrolled
environment. This transmitter must not be co-located or operating in conjunction with any
other antenna or transmitter. The minimum installed and operated distance between the
radiator and your body of each model as below.
For DRH3985A, please keep 2.54m or more.
For DRH3917A, please keep 2.17m or more.

Some Information
(a) The nominal passband gain is 37dB;
(b) The nominal bandwidth for each band is as follows:
850M (DRH3985A): 27.95MHz
AWS (DRH3917A): 48.05MHz
1900M (DRH3919A): 63.07MHz;
(c) The rated mean output power is 2*20W;
(d) The input and output impedance are 50Ω;
(e) The following notice:”The Manufacture’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 3.5dB, 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.”
