The RU performs the following functions:
Receives downlink baseband data from the BBU and sends uplink baseband data to the BBU. 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. Provides a built-in Bias Tee (BT). The built-in BT couples RF signals and OOK signals and transmits them through the TX/RX port A. The built-in BT also supplies power to the tower mounted amplifier (TMA).

Issue 05 (2014-06-30) Huawei Proprietary and Confidential Copyright Huawei Technologies Co., Ltd. 11 RRU3260 Installation Guide Requirements for the Installation Scenarios Application scenarios:
3 Information About the Installation To ensure proper heat dissipation of the RU, the following requirements must be met:
The RU cannot be installed in an enclosed cabinet without a cooling system. The RU cannot be installed in an enclosed camouflage box. The RU cannot be installed in an enclosed equipment room without a cooling system. When multiple RUs are installed in centralized mode, the minimum clearance requirements must be met. For details about the minimum clearance requirements, see 3.5.2 Clearances for Three or More RUs and 3.5.3 Installation Spacing Between RUs. RU mounting kits in assembled installation mode are not allowed in indoor scenarios. If the RU is improperly installed, heat dissipation of the RU deteriorates and the RU may not work properly, as shown in Figure 3-5. Figure 3-5 Improperly installed RUs Method of installation:
To ensure the heat dissipation of the RU and waterproofing of the ports at the bottom of the RU, the vertical deviation angle of an RU must be less than or equal to 10 degrees, as shown in Figure 3-6. On a tower, an RU can be installed on a pole, angle steel, or U-steel. The side-mounted installation mode (one side instead of the rear of an RU is mounted on the support) is recommended for RUs on the main pole secured on a tower. This installation mode allows multiple RUs to be installed next to each other at the same level on a pole. When the horizontal distance between the main and auxiliary poles on a tower is equal to or greater than 810 mm (23.62 in.), the side-mounted mode is recommended for installing RUs on the auxiliary pole to meet the minimum clearance requirements. Otherwise, the standard mode is recommended for installing RUs on the auxiliary pole.

If a cable listed below is not required, skip the routing requirements of the cable. General Cabling Requirements Requirements for Bending Radius The bending radius of the 7/8'' feeder must be more than 250 mm (9.84 in.), and the bending radius of the 5/4'' feeder must be more than 380 mm (14.96 in.). The bending radius of the 1/4'' jumper must be more than 35 mm (1.38 in.). The bending radius of the super-flexible 1/2'' jumper must be more than 50 mm (1.97 in.), and the bending radius of the ordinary 1/2'' jumper must be more than 127 mm (5 in.). The bending radius of the power cable or PGND cable must be at least three times the diameter of the cable. The bending radius of a fiber optic cable is at least 20 times the diameter of the fiber optic cable, and the minimum bending radius of the breakout cable at each end of the fiber optic cable is 30 mm (1.18 in.). The bending radius of the E1/T1 cable must be at least three times the diameter of the cable. The bending radius of the signal cable must be at least five times the diameter of the cable. Requirements for Cable Binding The same types of cable must be bound together. Different types of cable must be separately routed with the minimum spacing of 30 mm
(1.18 in.) and cannot be entangled. The cables must be bound tightly and neatly. The sheaths of the cables must not be damaged. Cable ties are installed in the same direction, and those at the same horizontal line must be in a straight line. The excess of indoor cable ties is trimmed off, and the excess of outdoor cable ties allows about 5 mm (0.2 in.), without remaining rough edges. Labels or nameplates must be attached to both ends, joints, or turns of cables after they are installed. Security Requirements Cables should be placed away from sharp objects or wall burrs. If these positions are inevitable, protect the cables with protection pipes. Issue 05 (2014-06-30) Huawei Proprietary and Confidential Copyright Huawei Technologies Co., Ltd. 81 RRU3260 Installation Guide 9 Installing RU Cables Cables must be routed away from heat sources, or heat-insulation materials are added between cables and heat sources. Sufficient slack (recommended for about 0.1 m [0.33 ft]) is provided in cables at turns or the position close to a device, facilitating cable and device maintenance. Indoor Cabling Requirements Cables are routed indoors through the feeder window. Drip loops must be made outside the feeder window, and the requirements for the minimum bending radius are met. When cables are routed indoors, engineers are required indoors for cooperation. The feeder window must be waterproofed. Outdoor Cabling Requirements Cables routed outdoors must be led through a pipe when they may be damaged. AC power cables, transmission cables, and cables buried in the ground must be protected. If cables at the cabinet bottom need to be routed through a pipe along the ground, lead the pipe into the cabinet base for about 30 mm (1.18 in.) to 50 mm (1.97 in.), not into the cabinet. Block the pipe with waterproof tape or silicon gel, and secure the pipe to the cable hole at the cabinet bottom with metal piece. If cables at the cabinet bottom need to be routed through a pipe along the metal cable trough, do not lead the pipe into the cabinet base. The cable trough must be sealed and routed through the cable hole at the cabinet bottom. When routing RU cables, ensure that the highest positions of the routes of all RU cables
(except RF cables and AISG cables) must be lower than the bottom of the RU. Cables are secured with cable clips. Cables are routed neatly along the specified cabling direction and secured with cable clips. The positions for cable clips are determined onsite. For example, the cable clips for the 7/8" feeder are installed at the spacing of 1.5 m (4.92 ft) to 2 m (6.56 ft) in the same direction, and the cable clips for the power cables are installed at the spacing of 1.5 m
(4.92 ft) to 2 m (6.56 ft) in the same direction. Cable clips must be vertical with cables, and the cables in a cable clip must be parallel. After routing cables neatly and correctly, tighten the screws on cable clips. Secure cables on the cable tray, as shown in Figure 9-1.

Issue 05 (2014-06-30) Huawei Proprietary and Confidential Copyright Huawei Technologies Co., Ltd. 83 RRU3260 Installation Guide Figure 9-2 Securing cables on the tower 9 Installing RU Cables Special Cabling Requirements Cabling Requirements for Power Cables Power cables must be installed in the position specified in engineering design documents. If the length of power cables is insufficient, replace the cables rather than adding connectors or soldering joints to lengthen the cables. Cables must be routed by only qualified and trained personnel before all preparations are made. Cables are routed in an untangled and orderly fashion. If DC power cables need to be routed on the tower platform, lay out the cables on the guardrail with the shortest distance and route the cables along the guardrail. Issue 05 (2014-06-30) Huawei Proprietary and Confidential Copyright Huawei Technologies Co., Ltd. 84 RRU3260 Installation Guide 9 Installing RU Cables If DC power cables need to be routed close to a device on the tower, secure the cables to the guardrail or pole with cable clips. The device cannot be far away from the position for securing the cables. Cabling Requirements for PGND Cables PGND cables for the base station must be connected to the same ground bar. PGND cables must be buried in the ground or routed indoors. They should not be routed overhead before they are led into the equipment room. The exterior of the coaxial wire and the shield layer of the shielded cable must have proper electrical contact with the metal surface of the equipment to which they are connected. PGND cables and signal cables must be installed in an untangled and orderly fashion. A certain distance must be reserved between them to prevent interference from each other. Fuses or switches must not be installed on the PGND cables. Other devices must not be used for electrical connections of the PGND cables. All the metal parts in the housing of the equipment must be reliably connected to the ground terminal. Cabling Requirements for E1 Cables E1 cables must not cross power cables, PGND cables, or RF cables when routed. If transmission cables are routed with power cables, PGND cables, or RF cables in parallel, the spacing between them must be greater than 30 mm (1.18 in.). E1 cables are routed straightly and bound neatly with cable ties. Sufficient slack is provided in E1 cables at turns. E1 cables cannot be squeezed by the cabinet door when routed through the cabinet, as shown in Figure 9-3. Figure 9-3 E1 cables routed through the cabinet Cabling Requirements for Fiber Optic Cables Fiber optic cables must be routed by at least three qualified and trained personnel before all preparations are made. Fiber optic cables are used within the temperature range of -40C to 60C. If the current temperature is out of the range, make protection measures or route the cables again. Cables are routed in an untangled and orderly fashion. Do not bind fiber optic cables at turns. Issue 05 (2014-06-30) Huawei Proprietary and Confidential Copyright Huawei Technologies Co., Ltd. 85 RRU3260 Installation Guide 9 Installing RU Cables Do not stretch, step on, or place heavy objects on fiber optic cables. Keep the cables away from sharp objects. When fiber optic cables are routed, the excess of the cables must be coiled around special devices, such as a fiber coiler. An unarmored fiber optic cable must be bound using binding straps. If a fiber optic patch cord needs to be secured in a cabinet or a piece of equipment, use binding straps to bind it and then use cable ties to secure the binding straps to the cabinet or equipment. Ensure that the fiber optic cables can flexibly move in the cable ties. Do not bend the fiber optic cables sharply. The following figure shows how to bind the fiber optic cables correctly. Figure 9-4 Binding fiber optic cables When coiling fiber optic cables, apply even strength. Do not bend the cables with force. Vacant optical connectors must be covered with dustproof caps. Fiber optic cables cannot be squeezed by the cabinet door when routed through the cabinet, as shown in Figure 9-5, Figure 9-6 and Figure 9-7. Figure 9-5 CPRI fiber optic cables routed through the cabinet (1) Issue 05 (2014-06-30) Huawei Proprietary and Confidential Copyright Huawei Technologies Co., Ltd. 86 RRU3260 Installation Guide Figure 9-6 CPRI fiber optic cables routed through the cabinet (2) 9 Installing RU Cables Figure 9-7 FE/GE cables routed through the cabinet If fiber optic cables need to be routed on the tower platform, lay out the cables on the guardrail with the shortest distance and route the cables along the guardrail. If fiber optic cables need to be routed close to a device on the tower, secure the cables to the guardrail or pole with cable clips. The device cannot be far away from the position for securing the cables. If the fiber optic cables close to a device are too long, coil the excess of the cables and secure them on the tower. 9.2 Cable Connections This section describes the cable connections for a single RU and multiple RUs.
