Implementation Issues - Cable Plant (Cont.)

• In general, there is no need to use conduits or inner duct when using cable trays, unless it is desired to provide extra protection against accidental cuts.
• If inner duct is desired for some reason, consider using PVC pipes. They are much cheaper and almost as effective.
• If inner duct or PVCs are used, pull wires should be installed with junction boxes atleast every 300ft on straight runs and every second 90° bent.
