MicroDucts and FuturePath

MicroTechnology is a term given to smaller conduits and fiber used in Inside and Outside Plant Construction (ISP and OSP). MicroDucts were developed as a solution to house fiber cables that were smaller in size, but still carried significant capacity. Today, MicroCables range from 6 to 432-fiber counts. The glass fibers are the same type as those used in traditional fiber cables, only the cable design has been altered to reduce the diameter of the cable sheath and support system. MicroDucts bundled under one sheath are called FuturePath and provide multiple ducts in one structure for future expansion of networks.



Dura-Line MicroDucts are the best way to utilize empty space and expand your fiber network as additional capacity is needed. Manufactured from 100% virgin grade HDPE, with a built-in permanently lubricated lining, SILICORE, these smaller conduits save you time and money while providing growth in your communications network.

  • Size range of 5mm OD to 18 mm OD
  • Smooth or Ribbed interior lining
  • Revitalize existing networks with Overrides
  • MicroDucts can either be Direct Buried (DB) or installed in an existing conduit (DI)
  • Customize with color, stripe, print markings, and more
  • Available in HDPE, or fire retardant Riser, Plenum or LSZH materials

Aerial Drop Duct

Aerial Drop Ducts are a cost-effective total solution for drop optical fiber cables when distributing Fiber to the Home solutions in an aerial environment. This ruggedized product is fully UV and thermal standardized for use in outdoor aerial exposed applications for up to 25 years.

  • Flexible and easy to install on poles (max span 30 meters)
  • Dielectric, non-metallic for wide range of accessories for all weather conditions
  • Size range: 7-12mm OD
  • Meets standard tests for: climactic aging, corrosion, mechanical and vibration


MicroDucts bundled into an easy-to-handle unit known as FuturePath. The MicroDucts are lined with Silicore to reduce friction during cable placement. FuturePath is placed as a cable pathway allowing the network to expand as needed, while placing only the cable required for immediate needs. Using reduced diameter Fiber Optic Cable (MicroCable), FuturePath can accommodate fiber cable over 288 cost fibers per MicroDuct or more, depending on the design. FuturePath is installed like standard conduit, no special tools are required, providing easy, one-step placement of multiple pathways. Place the fiber needed today, leaving empty pathways for future network expansion.

  • Standard Configurations: 2-way, 3-way, 4-way, 7-way, 12-way, 19-way, 24-way
    MicroDuct Size: Range from 5mm OD to 18mm OD
  • Cost effective – multiple pathways for one installation cost
  • Ships on standard reels or coils
  • Designed for Direct Buried (DB) underground or Direct Install (DI) inside existing pathways

FuturePath Figure-8 Aerial

FuturePath Figure-8 Aerial is a bundled package of MicroDucts for easy installation in an aerial environment. FuturePath makes the best use of limited available space on the pole while reducing installation cost and time to deploy. No special installation hardware or tools needed for deployment other than standard aerial installation equipment.


  • MicroDucts factory bundled with a polyethylene oversheath
  • Configurations: 7-way or 4-way
  • Extra High Strength Galvanized Steel Strand
  • Utilizes industry standard aerial strand hardware
  • Black UV outer sheath
  • Multiple pathways in place for future growth

FuturePath Flat

MicroDucts arranged in a "flat" or "linear" configuration are the perfect solution primarily designed for lat mile customer connection. This bundled configuration works in many different installation techniques including Direct Buried, Vertical Long-Haul, aMicroTrenching, and also indoor behind the wall installations.


  • Highly flexible, can be rolled for installation
  • Up to 7 MicroDucts within one bundle
  • Customizable with MicroDuct size and color, jacket color, stripe and print line
  • User-Friendly deployment of more than one MicroDuct at one time

FuturePath In-Building

Dura-Line manufactures a wide range of highly specialized MicroDucts and FuturePath products engineered for use inside building and in areas where fire, smoke, or toxicity and critical factors to consider for human and asset safety. These areas are typically confined spaces like tunnels, or data centers where certain fumes can cause damage to sensitive equipment. These specialized products are manufactured to comply to relevant International Standards and National Building Code. They have the same unique properties as standard FuturePath, allowing flexible, expandable networks.


  • Low Smoke Zero Halogen (LSZH) fire-retardant material recommended for indoor tunnel applications manufactured to relevant EN & IEC standards
  • Riser Rated products are used within buildings, whether vertical or horizontal, in backhoe applications and workstation drops. Products are UL/ETL listed to UL 20204
  • Plenum Rated products are used exclusively in designated return air plenums and under floor return airspaces
  • Size Range: MicroDucts are available from 5 mm to 18 mm Outer Diameter, with bundled configurations from 2-way to 24-way

FuturePath Jumbo
