Cable Tray Support Systems

Each access provider should have at least one metric designator 103 (trade size 4) conduit at each entrance point.

Additional conduits may be required for campus cabling. Conduits used for optical fiber entrance cables should have three inner ducts [two metric designator 40 (trade size 1.5) and one metric designator 27 (trade size 1) or three metric designator 32 (trade size 1.25)]. Consider the use of soft-sided duct material as a substitute for inner duct, which may optimize the use of finite conduit cross-sectional area.

All cables should be tied and labeled, and cables shall not be left abandoned under the access floor. Cables shall be terminated on at least one end in the MDA or an HDA or shall be removed.
