OSP Materials is the manufacturers representative for LYNDDAHL Telecom America across Michigan, Indiana, and Ohio. We help contractors, utilities, and broadband builders specify and source LYNDDAHL’s customizable HDPE microduct and conduit systems — so fiber installs move faster, stay protected, and stay ready for future cable blows.
Why LYNDDAHL microduct
Traditional conduit is often overbuilt for today’s fiber counts and underbuilt for tomorrow’s upgrades. Microduct lets you place pathways sized for air-blown fiber, bundle multiple ducts in one trench or bore, and add capacity later without a full dig-up. LYNDDAHL builds complete, tailored pipe solutions — not a one-size SKU — with production in Belmont, North Carolina and Ribe, Denmark, and U.S. manufacturing positioned for BEAD / BABA-aligned projects.
What OSP Materials helps you specify
- Microduct sizes from 5 mm to 27 mm, colors, and bundle configurations
- Thick or thin wall; smooth or ribbed inner surfaces for blow performance
- Sheathed outdoor bundles and indoor microduct options
- Fittings and accessories: couplers, reducers, end caps, and related path hardware
- Pathway design matched to plow, trench, or directional install methods
LYNDDAHL Microduct Sizes and Specifications
LYNDDAHL HDPE microduct is available from 5 to 27 mm OD as single ducts or 2- to 24-way bundles, with smooth or ribbed inner surfaces and an optional co-extruded low-friction lining, made in Belmont, NC.
