Direct Installation (DI) 24-way 8/5mm+1-way 10/8mm (PE Sheath 1.7mm)

HDPE Tube Bundle

Direct Installation (DI) 24-way 8/5mm+1-way 10/8mm (PE Sheath 1.7mm)

A bundle of micro- or mini-tubes with strengthened wall thickness is encased in a single thin HDPE sheath, forming a duct assembly specifically engineered for fiber optical cable deployment. This robust design enables versatile installation—either retrofitted into existing ducts or directly buried underground—supporting seamless integration into fiber optical cable networks.

The micro ducts are optimized for high-efficiency fiber optical cable blowing, featuring an ultra-smooth inner surface with low-friction properties to minimize resistance during air-assisted cable insertion. Each micro duct is color-coded per Figure 1, facilitating quick identification and routing of fiber optical cable types (e.g., single-mode, multi-mode) during network installation and maintenance.

  • Bundle Tube Type all Dielectric ASU Self-Supporting Optical Cable

    Bundle Tube Type all Dielectric ASU Self-Suppor...

    The structure of the optical cable is designed to connect 250 μm optical fibers. The fibers are inserted into a loose tube made of high modulus material, which is then filled with waterproof compound. The loose tube and FRP are twisted together using SZ. Water blocking yarn is added to the cable core to prevent water seepage, and then a polyethylene (PE) sheath is extruded to form the cable. A stripping rope can be used to tear open the optical cable sheath.
