What is Innerduct used for?
Innerduct refers to smaller diameter conduits (i.e., ducts, conduit, or tubes) that are used to divide larger conduits into subsections. They facilitate the proper placement and positioning of fiber optic cables in underground conduit systems.
What is fiber Innerduct?
Innerduct is a plastic tube, rated for the environment in which it is installed (such as plenum or riser) that is pulled into place to act as a pathway for the fiber optic cable.
What is Innerduct made of?

Can you bury Innerduct?
Innerduct — Multiple lengths in sizes usually 1-1/4″ and smaller pulled parallel into a larger conduit to divide it into multiple conduits. Direct Buried — Burying one or more conduit lengths directly in the ground as pathways for future cable installation.
Is Innerduct required for fiber?
If future cable pulls in the same duct or conduit are a possibility, fiber optic innerduct should always be used. Without it, future fiber cable pulls can entangle existing operating fiber cables and cause service interruption.
What is the difference between Innerduct and conduit?
Innerduct has become a generic term used to describe most any type of duct, conduit or premise wiring raceway. Conduit and duct usually refer to a stand alone tube vs. innerduct which refers to a duct installed inside of another duct to subdivide that duct into multiple pathways for cables.
How do you size an Innerduct?
As a rule of thumb, 2~4 pcs of 1” (25.4mm) innerduct can be pulled through a 100mm conduit. The most popular fiber optic innerduct sizes are 1” (25.4mm) and 1.25” (31.8mm). Fiber cables with a maximum diameter of 1” (25.4mm) can be pulled in 1.25” innerduct.
How do you pull an Innerduct?
Preparing innerduct for pulling
- While it is still on the spool, cut off approximately the first 10 feet of innerduct from the end to be pulled, using an innerduct cutter.
- After you discard the excess, use a knife to notch the end of the innerduct that will be pulled, again being sure not to cut the pullstring.
Can I run fiber and electrical in the same trench?
Yes, fiber can be run near power. Fiber signal is transmitted as light which does not experience the same interference issues as other electrical signals.
How deep should fiber be buried?
Corning Cable Systems recommends that fiber optic cable be buried a minimum depth/cover of 30 inches (77 cm).

What is the difference between innerduct and direct bury?
Innerduct — Multiple lengths in sizes usually 1-1/4″ and smaller pulled parallel into a larger conduit to divide it into multiple conduits. Direct Buried — Burying one or more conduit lengths directly in the ground as pathways for future cable installation.
What is the color of the innerduct?
