EPFU Enhanced Performance Fibre Units Air-Blown Micro Optical Fiber Cable For FTTX Network FTTH
■ Introduction:
The EPFU cable is designed for use in FTTx networks, particularly for FTTH (Fiber to the Home) applications. It features a core made of optical fibers and filler elements arranged in parallel within photosensitive resin. This is then encased in a low-friction material forming the outer sheath. The cable is specifically engineered with grooves that facilitate long-distance air-blowing installation using air-blowing equipment.
■ Features:
- Available in 2, 4, 6, 8, and 12 fiber options.
- Uses G657A2 bending-insensitive fibers.
- Stable structure with excellent mechanical and temperature performance.
- Special grooves enhance blowing distance.
- Lightweight with appropriate stiffness for repeated installations.
- Gel-free design makes stripping and handling easy.
- Cost-effective compared to traditional cables.
- Complete accessories included, reducing manpower and installation time.
