2.1.5 Cable Routing
Ensure all cables, e.g. power cable, feeder cable, optic fiber, commissioning cable, connecting
are properly routed and secured so that they are not damaged.
2.1.6 Manual Handling
During transportation and installation, take necessary handling precautions to avoid potential
physical injury to the installation personnel and the equipment.
2.2 Installation Requirements
• Working space available for installation and maintenance for each mounting arrangement.
Ensure unrestricted airflow.
• Ensure grounding connector is within reach of the ground wire.
• Ensure a power source is within reach of the power cord and the power source has
sufficient capacity.
• Where appropriate, ensure unused RF connectors are terminated.
• Do not locate the equipment near large transformers or motors that may cause
electromagnetic interference.
• Reduce signal loss in feeder cable by minimizing the length and number of RF connections.
• Ensure the equipment will be operated within the stated environment (refer to datasheet).
• Where appropriate, confirm available of suitably terminated grade of RF and optical fiber.
• Observe handling of all cables to prevent damage.
• Ensure same length for a pair of optic length for units in MIMO scenario.
2.3 Fiber Optic Rules
Attention!
Please refer to the Laser Safety section in the document Preface.
• Fiber optic cables require proper handling. Do not stretch, puncture, or crush the fiber
cable(s) with staples, heavy equipment, doors, etc.
• Always maintain the minimum bending radius specified by the cable manufacturer. The
minimum bend radius is usually 10 times the cable's outer diameter. In the case of single
optical fiber that is not in a cable, the minimum bending radius to be observed is 30mm.
• WDM, Wave Division Multiplexing, units require SMF
• Use SC/APC connectors (green color) 8 deg only.
• Use minimum splicing/connectors to achieve minimum losses on the fibers.
• Use precaution while installing, bending, or connecting fiber optic cables.
• Use an optical power meter and OTDR for checking the fiber optic cables.
• Make sure the environment is clean while connecting/splicing fiber optic cables.
• All fiber optic connections should be cleaned prior to attaching to termination points using a
dry cleaning device (i.e. Cletop or equivalent).
• Fiber connector protective caps should be installed on all non-terminated fibers and removed
just before they are terminated.
• Check the Fiber Optic connections.
• Pay special attention while connecting the SC/APC connectors - you must hear the “click”
when the connection is made.
