DRH3985A&3917A&3919A&3919B Hardware Description 2 DRH Introduction DRH Introduction This chapter describes the function and exterior of the DRH as well as the ports and indicators on the DRH. 2.1 DRH Exterior This section describes the exterior and dimensions of a DRH. Figure 2-1 shows an DRH. Figure 2-1 DRH exterior Figure 2-2 shows DRH dimensions. Issue Draft A (2013-08-18) Huawei Proprietary and Confidential Copyright © Huawei Technologies Co., Ltd. DRH3985A&3917A&3919A&3919B Hardware Description 2 DRH Introduction Figure 2-2 DRH dimensions 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. Issue Draft A (2013-08-18) Huawei Proprietary and Confidential Copyright © Huawei Technologies Co., Ltd.

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 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.

This equipment complies with IC 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. Issue Draft A (2013-08-18) Huawei Proprietary and Confidential Copyright © Huawei Technologies Co., Ltd. 23 DRH3985A&3917A&3919A&3919B Hardware Description 5 Appendix For DRH3919A, please keep 2.24m or more. Cet équipement est conforme àl'exposition aux rayonnements IC limites établies pour unenvironnement non contrôlé. Cet émetteur ne doit pas être Co-placéou ne fonctionnant en même temps qu'aucune autre antenne ou émetteur.La distance d’installation et d’opération entre le radiateur et votre corps de chaque équipement doit être au minimum : Pour DRH3985A, 2.54m ou plus. Pour DRH3917A, 2.17m ou plus. Pour DRH3919A, 2.24m ou plus. 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.” Issue Draft A (2013-08-18) Huawei Proprietary and Confidential Copyright © Huawei Technologies Co., Ltd. 24
