Microducts are designed for long term protection of fiber optical cables. Direct Bury (DB) type of microducts are thick wall products that attain their mechanical robustness and functional performance through their intrinsic thick walls and need no further protection at underground installations.
The microduct bundle can be used as a direct buried product, meaning it can be installed directly into the ground.
It can also be used as a direct install product, where it is installed into an existing duct.
Construction of the Product
Microduct bundles are constructed using high density halogen-free polyethylene (HDPE) material.
Each microduct contains a permanent inner liner made of co-extruded silicone compound, which results in a low coefficient of friction (less than 0.1.
The inner surface of the microduct can be manufactured with either longitudinal grooves or a smooth finish.
The bundle is equipped with a sheath that is suitable for installation, handling, and marking.
The microducts come in customizable colors, allowing for aesthetic preferences or specific coding needs.
Both fully colored microducts and natural-colored microducts with colored stripes are available.
Metallic Tracing Wire:
An option for including metallic tracing wire is available.
This tracing wire helps in detecting the installed bundle of microducts during its lifetime.
Customers must specify whether they want the inclusion of tracing wire when placing an order
