INTRODUCTION

The purpose of this Technical Note is to provide a practical comparison of highdensity polyethylene (HDPE) conduit (innerduct and micro duct), and fabric divider technologies, two options for sub-dividing installed larger conduit. For the purpose of clarity, both HDPE innerducts and micro ducts may be referred to as "HDPE conduit" when referencing both options simultaneously in this document, whereas Fabric Divider will be referenced as "Fabric Divider". Both technologies are used to house and protect fiber optic cables for various applications.

This Technical Note will focus on comparing each technology's installation techniques, advantages, strengths, and protection capabilities, along with cable installation considerations. It is intended to assist specifiers, contractors, and others with useful selection criteria when determining which technology to employ.
