3.3 Coaxial Cable Connections
3.3.1 General Cable Installation Procedures
Observe the general cable installation procedures that meet with the building codes in your area.
The building code requires that all cabling be installed above ceiling level (where applicable).
Each length of cable from the risers to each antenna must be concealed above ceiling.
The cable must be properly supported and maintained straight using tie-wraps, cable trays and
clamps or hangers every 10 feet (where practical above ceiling level). Where this is not practical,
the following should be observed:
• The minimum bending radius of the supplied ½” coax cable should be 7”.
• Cable that is kinked or has a bending radius smaller than 7” must be replaced.
• Cable runs that span less than two floors should be secured to suitably located
mechanical structures.
• The cables should be supported only from the building structure.
3.3.2 Fiber Optic Rules
• Use only single mode fiber for indoor applications.
• Use only 8-degree SC/APC connectors (green color).
• Use only fusion splice for connecting two fibers.
• Use minimum splicing/connectors to achieve minimum losses on the fibers (<0.5dB).
• 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.
• Verify the Fiber Optic connections. You may use the Optical Test Procedure described at
the end of this manual.
• Pay special attention while connecting the SC/APC connectors - you must hear the “click”
when the connection is made.
