Product Information


Simplifying the placement of fiber, while providing protection from harsh environmental elements, FieldShield Direct Bury 10/6 mm Microduct is specifically designed for applications requiring a small heavy duty drop feed. Rugged crush resistance protects FieldShield Direct Bury Microduct from the rigors of all industry standard ground deployment methods, while rigid column strength allows microducts to be deployed through occupied duct previously thought exhausted. Direct Bury 10/6 mm Microduct has an outer diameter of 10 mm and an inner diameter of 6 mm.

FieldShield Direct Bury 10/6 mm Microduct is a durable and crush resistant micro-conduit designed to increase the protection of fiber while decreasing installation and maintenance expenses. Manufactured using high density polyethylene (HDPE), FieldShield Direct Bury Microduct offers superior durability and protection.

Features and Benefits


  • Compliant to Telcordia GR-3155


  • Quick and easy to install
  • Direct Bury Microduct has high tensile strength and crush resistance that withstands all types of ground implementations including open trenching, vibratory plowing, micro-trenching and directional boring
  • Made from HDPE to prevent degradation


  • Optional external tone wire simplifies ground locating
  • Industry standard orange provides high visibility for direct bury applications
  • Standard nylon pull string simplifies deployment of fiber
  • Smooth core slip lining reduces drag co-efficient enabling fiber to be pushed or pulled with minimal resistance
  • Optional black color available to couple direct bury orange to a more aesthetically pleasing black color as it transitions above ground on the side of a living unit


  • Maximizes capacity of existing conduit previously considered exhausted
  • Provides industry leading protection for “last mile” feeds
