The ASU/Mini ADSS design uses a compact, light-weight, single loose tube architecture that delivers robust mechanical strength and weather protection:
Optical Fibers (8 / 12 / 24 Cores): High-grade single-mode optical fibers (compliant with ITU-T G.652D) housed within a central PBT loose tube. Fibers are standard color-coded (Blue, Orange, Green, Brown, Slate, White, Red, Black, Yellow, Violet, Pink, Aqua) for rapid identification during splicing.
Moisture & Hydroblock Filling: The loose tube is injected with a specialized water-blocking jelly compound. Hydro-expandable dry materials inside the cable core further prevent longitudinal water ingress, ensuring maximum signal stability over decades.
Non-Metallic Strength Members: Integrated with two parallel Fiber Reinforced Plastic (FRP) rods placed on opposing sides of the cable core. These FRP members handle the necessary tensile forces, enabling self-support across 80m–120m spans without metal conductors.
UV-Stabilized Outer Sheath: Extruded with high-density Polyethylene (HDPE) or low-smoke zero-halogen (LSZH) jacket materials. This jacket offers long-term resistance against intense ultraviolet radiation, extreme thermal cycles (-40°C to +70°C), physical abrasion, and environmental stress cracking.
| Parameter | Specification Detail |
| Fiber Core Options | 8 Cores, 12 Cores (12 Hilos), 24 Cores |
| Fiber Type | G.652D Single-Mode (SM) |
| Cable Structure | Central Uni-tube + Dual FRP Strength Members |
| Installation Type | Aerial Self-Supporting (Pole-to-Pole / Pole-to-Building) |
| Operational Span | 80 Meters to 120 Meters (Customizable up to 150m) |
| Outer Sheath Material | UV-Resistant Black HDPE / PE |
| Outer Diameter (OD) | ~6.5 mm – 8.0 mm (Depending on core count) |
| Approximate Weight | ~40 kg/km – 60 kg/km |
| Attenuation @ 1310 nm | $\le 0.36\text{ dB/km}$ |
| Attenuation @ 1550 nm | $\le 0.22\text{ dB/km}$ |
| Grounding Requirement | None (100% All-Dielectric / Non-Metallic) |
100% Dielectric Safety (No Grounding Required): Containing zero metallic components, the ASU cable is completely immune to electromagnetic interference (EMI) and electrical induction. It can be strung safely along low-to-medium voltage power lines and utility poles without risk of electrical discharges, short circuits, or lightning damage.
Simplified & Economical Installation: Because it is self-supporting, technicians do not need to install steel lashing wires or separate messenger cables. The compact diameter and lightweight nature allow for fast deployment using standard tension and suspension clamps, significantly reducing installation labor and time.
Superior Climate Resilience: Water-blocking jelly and high-density outer sheathing safeguard optical performance under heavy rain, high winds, snow accumulation, or continuous heat exposure.
FTTH / FTTx Last-Mile Access Networks: Secondary aerial distribution links between main trunk closures and local subscriber distribution boxes (FAT/ODP).
Rural & Suburban Regional Telecom: Connecting remote areas across short-to-medium pole spans efficiently.
Smart City & Outdoor CCTV Backhaul: High-capacity, interference-free optical links for urban surveillance systems, traffic control devices, and enterprise inter-building connections.

ASU Mini is a compact single loose tube aerial cable with non-metallic strength members. It is designed for self-supporting outdoor aerial runs where light weight, small diameter and dielectric construction matter more than very long spans.
The compact ASU construction typically self-supports spans of about 80 to 120 metres without metal conductors. Longer or heavily loaded crossings should be specified as full ADSS with aramid yarn reinforcement.
Common builds are 8, 12 and 24 cores of G.652D single-mode fibre in a PBT loose tube with water-blocking fill, FRP strength members and a UV-stabilised HDPE or LSZH sheath rated from -40 to +70 degrees Celsius.
