8.3. Cable Guidelines
The following lists cable installation guidelines at the subscriber's premises:
! To prevent tripping, a wiring duct is to be provided at the subscriber's premises
to house data cables. Wiring channel type, location, and methods of securing are
to be discussed with the subscriber.
! Cables not housed in wiring channel must be dressed in a manner to avoid a trip
hazard. Avoid trailing wires across passageways.
! External data cables are to be protected in metal conduit that is to be secured to
the building structure in accordance with manufacturers recommendations.
! Outside wiring channels must not be located as to cause a trip hazard (e.g. roof
walkways)
! Observe recommended minimum bend radii when installing copper cables.
Wherever a cable changes direction, ensure that it does so in a smooth curve
with a radius of at least 50 mm in order to prevent damage.
! A maintenance loop is to be left in the cable just before the cable reaches the
SPR to prevent strain on the connector.
! Data cables threaded into holes drilled in walls are to be covered by a waterproof
sheath to prevent water penetration.
! Silicone sealant should be used to plug any holes on both internal and external
wall surfaces once cables are in place.
! All data cables should be labeled with both the source and destination at each
end. Un-used cable ends must also be identified with labels to assist with future
upgrades.
Warning: Cables with exposed ends (i.e., not yet crimped) should be covered
with protective polythene bags during external cable installation processes.
Note: A minimum separation of 200 mm should exist between power and data
cables.
