Enhanced Performance Fibre Units (EPFU)
Air-blown Micro Optical Fibre Cables for C-NET                            

Micro air-blown fiber unit (MABFU)

Introduction:

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.

Features and Benefits:

● 2、4、6、8 and 12 fibres options.
● Stable structure, good mechanical and temperature performance.
● Designed with special grooves to advance blowing distance.
● Lightweight and proper stiffness , repeat installation.
● Designed with no gel, easy stripping and handling.
● Better costs advantage compared to traditional product.
● Complete accessories, less manpower, lower installation time.

Note: It is recommended that the structure of 2 fibres unit consist of 2 filled fibres, for it is proved that 2 fibres unit
with 2 filled fibres is better than the one with zero or one filled fibre in the blowing performance and the fibre stripping-ability
