■Product Overview
Air-Blown Fiber Unit (BFU/EPFU) is a compact fibre unit designed for air-assisted installation into microduct networks. It is typically used to expand capacity by blowing additional fibre units through existing microducts without re-opening civil works.
■Typical Applications
Microduct networks for FTTH / access build-out
Staged expansion projects (add fibres when demand increases)
Duct bundle retrofit and restoration routes (route-dependent)
■Construction
Optical fibers: 250 μm (standard) or 200 μm (optional for higher density, subject to availability)
Unit body: fibre bundle with protective polymer layers
Outer jacket: low-friction thermoplastic (commonly HDPE-based), UV-resistant
■Available Fiber Types
Single-mode: ITU-T G.652.D, G.657.A1/A2 (by request)
Multimode: OM3/OM4 (by request)
■Technical Specifications (Typical / Configurable)
Values below are typical targets for BFU/EPFU products; final performance depends on unit OD, microduct ID, route profile, and blowing equipment settings.
■Fiber Count Options
Common: 1 / 2 / 4 / 6 / 8 / 12 fibers
Optional: 24 fibers (usually requires higher density fibre and a larger unit OD)
■Dimensional Range (Typical)
Item Typical Range Nominal OD 1.1 – 2.3 mm (depends on fiber count and fiber diameter) Unit weight ~1 – 4 kg/km (configuration dependent) ■Environmental
Item Typical Range Installation temperature -10 to +50°C Operating temperature -30 to +70°C Storage/transport -40 to +70°C ■Blowing Compatibility (To be specified per project)
Compatible microduct ID: commonly 3.5–5.0 mm ID for small units (varies)
Blowing distance: route dependent (duct cleanliness, joints, bends, lubricant, pressure, equipment)
■Marking & Packaging
Supplied on reels/spools; delivery length and reel size by agreement
Packing label typically includes fiber count, fiber type, length, and batch information
■Ordering Information (RFQ Copy)
Please specify: fiber count, fiber type (G.652.D / G.657 / OM), fiber diameter (200/250 μm if required), target microduct ID, and delivery length per reel.
