How many cables can be placed in an innerduct?
• In the underground cable plant the general rule is one cable to one innerduct. This allows future access to each cable individually if the need should arise to remove or replace it. If multiple cables are placed in a innerduct all cables will have to be removed to remove one due to spiraling of the cables when placed. In the premise plant when plenum and riser products are being installed the general rule is a fill of no more than 40% of the ID.
