For the signal cable that is often bent or pulled out/plugged in, the bending radius should be at least 7 times larger than its diameter. The cables should be bundled as follows:
l l l l Cables of different types should be routed separately. The cables cannot be coiled. The cables should be tightly and neatly bundled. Ensure that the jackets of the cables are not damaged. Two adjacent cable ties should be spaced 200 mm and face the same direction. The cable ties at the same horizontal line should be on the straight line. Extra length of cable ties should be cut off. Labels or nameplates should be attached or bundled on the cables after they are installed. The cables should be routed in category as follows:
l l l Cables of different types should be routed separately. Cables of different types cannot be crossed. Space between cables of different types should be larger than 30 mm when the cables are routed parallel inside the cabinet. Space between cables of different types should be larger than 100 mm when the cables are routed parallel outside the cabinet. If such requirements cannot be met, the cables should be separated with specified objects. Special Cabling Specifications Cabling specifications for routing the power cables and the PGND cables are as follows:
l l l l l l l Positions of routing the cables should meet requirements of the engineering design and the general cabling specifications. If the cable is not long enough, replace the cable. Do not add connectors or solder joints to lengthen the cable. Insulating treatment should be done on the cables if they need to be bundled and routed on the metal cable racks. Do not install fuses or switches on the cables. The -48 V power cable and GND cable should be bundled together. Grounding points at both ends of the PGND cables should be in proper electric contact and processed with antirust treatment. The low-voltage AC power cable for the NodeB should be covered with a metallic conduit and be buried in the ground for at least 50 m before they are led into the equipment room. Note that if such cables are shorter than 50 m, they should be completely buried in the Issue 01 (2007-11-29) Huawei Technologies Proprietary 3-79 3 Installing RRU3804 and SRXU Hardware RRU3804 User Guide ground. If such cables are routed overhead and led into the room, surge protection for the connector of the AC power cable will be affected. The PGND cables should be buried in the ground or routed indoors. The PGND cables should not be routed overhead before they are led into the equipment room. l The specifications for routing the E1/T1 cables are as follows:
l l l l l l l Positions of routing the cables should meet requirements of the engineering design and the general cabling specifications. The cables should not be routed overhead outdoors. If the cables have to be routed outdoors, the cables should be covered with metallic conduits which are reliably grounded at both ends. If the cables have to be routed outdoors and it is impossible to install them under the ground, they should be covered and shielded with metallic conduits which are reliably grounded outdoors or connected to the grounding bar in the room. If the cables are covered with metallic jackets, ensure that both ends of each jacket are reliably grounded outdoors or connected to the grounding bar in the room. Extra length of E1 cables should be reserved when they are curved. Before the E1 cables are led out of the cabinet, they should be properly grounded. The wires not in use should be grounded in the equipment room. The specifications for routing the optical cables are as follows:
l l l l l l l l l Positions of routing the cables should meet requirements of the engineering design and the general cabling specifications. Extra length of the optical cable should be reserved at the point that the cable is curved. Do not stretch the optical cables, step on the cables, or place heavy objects on the cables. Keep the cables away from sharp objects to avoid damage. The optical cable that is curved or pressed or the optical connector which is damaged cannot be used. Extra optical cables should be coiled on the specified device such as the fiber coiler. Use moderate force to coil the optical cables. Do not bend the cables forcibly lest they be damaged. PVC corrugated tubes should be used to cover the optical cables for protection purpose when they are led out of the cabinet. Dustproof caps should be used to cover the optical connectors not in use. If one end of the optical cable is connected to an optical device, do not look directly at the end face of the optical connector. Otherwise, your eyes may be hurt. Use soft materials such as fireproof cotton to fill in the optical connector at the top of the cabinet. You need to check whether the optical connector is polluted before installing the cables.
