B-Lite™ Micro-blown cables
High speed and long reach in access networks

Build your FTTH network with KINOPTIC solutions

Short description of the solution

Micro-blown cables are compact and low friction cables that can be installed inside microducts. These microducts have a smaller size (typically 8/10mm) compared with traditional ducts (45/50mm). Nexans micro-blown cables allow an optimization of the duct occupancy rate and provide a better cable / fiber optic density.

Advantages of the solution

Fast installation

  • More flexible infrastructure
  • The installation of microducts is done in a one step process. The possibility to have separate microducts allows to have individual cable management and to optimize the fibre count in different sectors of the network

Fast & Easy cable installation and removal

  • Blowing speed of 60 meter per minute
  • Easy removal without disturbing the other cables as the cable is in an individual microduct

Compact cables

  • The drums are lighter and easier to move
  • Cable coiling is much easier

Long reach installation

  • Low friction coefficient is optimized with lubricant input
  • The distance is then much longer compared to traditional duct installation

Easy mid span access

  • Special toolingSpecial toolings have been developed to remove in a safe way the external sheath
  • The micro bundle structure is easy to remove with a direct access to the fibres
  • This structure is thus optimized for frequent mid span access (urban connexions)
  • The bundle structures provide an easy coiling and avoid kink issues


  • Possibility to push on 100+ meters
  • The cable can be pushed manually of mechanically for fibre to home access without the need of air compressor
