Optical Fibre Cable Extrusion Line Manufacturers in India

Introduction

Optical fibre cable lines differ fundamentally from conductor-insulation lines: instead of coating a metal conductor, they apply protective buffer and sheathing layers around delicate glass or plastic fibres under tightly controlled, low-tension conditions. Excess heat or tension damages the fibre, so these lines prioritise gentle handling and precise micro-layer control.

Sai Extrumech supplies secondary coating and sheathing lines using PBT for loose-tube buffering and PE/LSZH for outer jackets, with small-bore precision extruders, fibre pay-off with active tension control, excess-fibre-length (EFL) management, and water or air cooling calibrated to prevent post-extrusion shrinkage. Tight-buffer lines apply a thin UV-cured or thermoplastic layer directly over the coated fibre.

Applications:

  • Telecommunications and broadband infrastructure
  • FTTH (fibre-to-the-home) drop and distribution cables
  • Data-centre interconnect and long-haul backbone
  • Indoor tight-buffer patch and riser cables

Why Sai Extrumech: Our buffering and sheathing lines are tuned for stable, low-tension processing so fibre attenuation stays within spec across the full production run.
