EPFU Air-blown Micro Cables for C-NET

MABFU is the important part of the air blown fibre cable, and it is the most popular product of the indoor optical fibre cables for generic cabling in Europe、Japan 、South Korea and so on.
The MABFU is the product that with small diameter, lightweight, highly flexibility and proper stiffness, and it can be blown into the microduct of 5.0/3.5mm. The fibres are coated with a soft acrylate resin which provides excellent dimensional and thermal stability to cushion the fibres, in addition, the resin can be easily stripped in connecting the fibres. The outer sheath is a thermoplastic that is of low friction.
The surface of the sheath is designed with special grooves, compared to the surface of the traditional optical fibre cable, it provides not only the high level of mechanical protection, but also the perfect blowing performance.

Product Name: Enhanced Performance Fibre Units (EPFU)

Fiber: ITU-T G.652.D/G.657A1/G.657A2, OM1/OM3/OM4 Fibers
