Do I need a separate steel messenger wire when installing ASU?

No. ASU is self-supporting. FRP rods bear the aerial tension. It saves messenger wire, clamps and installation labor cost compared with figure-8 cable.

What fittings should I use for ASU cable?

Use dedicated mini ADSS / ASU fittings: suspension clamp, tension clamp, vibration damper, downlead clamp. Ordinary figure-8 fittings are not recommended.

What is the outer sheath material?

Standard: Black UV-stabilized HDPE. Optional: LSZH (low smoke zero halogen) for special fire safety requirements.

Can ASU be buried directly or put into ducts?

Not recommended. ASU is designed for aerial use only. For duct or direct burial, please choose GYTA/GYTS type cables.

Can ASU be used under high voltage power lines?

Only for short span and low voltage adjacent scenarios. Standard long-span ADSS is the correct solution for high voltage crossing.

Key features

All-dielectric non-metallic structure, completely immune to electromagnetic and lightning interference.

The outer sheath is made of weather resistant PE material, which has excellent UV resistance and high and low temperature resistance.

Supports multi specification configurations such as 2-24 cores, with options for single-mode and multi-mode.

The integrated FRP reinforcement provides high tensile strength.

It can withstand long-term outdoor wind, sun, snow and ice loads, and has a longer service life.

All-dielectric construction, no metal, lightning & EMI immune, no earthing required

Self-supporting aerial design, no separate steel messenger wire, save hardware & labor cost

Small diameter & lightweight, low load on utility poles, easy handling & installation

Central loose tube with water-blocking gel, excellent waterproof & stable optical performance

Bend-insensitive G.657A1/A2 fiber optional, low attenuation, good for FTTH last mile

AI-Powered supplier vetting

SummaryThe supplier operates in intelligent optical equipment, optical and communication cable production, robots, and related network and security equipment. It reports more than 10 production lines, multiple customization modes, OEM service for well-known brands, CAD-based R&D, an available SDK, and five R&D patents. However, R&D audit documentation is unavailable, supplier-management-system certification is listed as NIL, overseas service infrastructure is absent, and only limited service-capability evidence is provided. Financial information is reported as zero across the stated indicators, but no financial conclusion is made here because monetary and financial figures are excluded. Customer-case evidence is not provided.

Supplier typeThe supplier’s stated business scope covers intelligent optical equipment, optical cable auxiliary production robots, optical and communication cables, communication equipment, and related computer, network, security, and data-center products. This indicates a manufacturer and seller of industrial optical and communication products rather than a service-only supplier.

CertificationsSupplier-management-system certification is explicitly listed as NIL. No other certification evidence is provided in the slices, so the supplier does not demonstrate certification holding for this field.

R&D capabilityThe supplier reports CAD capability, an available SDK, five R&D patents, and R&D engineers responsible for new-product design and technical support. At the same time, only one year of total R&D-engineer experience is stated and required R&D audit documents are unavailable, so the evidence supports some innovation resources but not a fully verifiable R&D system.

Production capacityThe supplier operates more than 10 production lines and lists extensive equipment covering ribbon, loose-tube, sheath, stranding, coloring, twisting, and extrusion processes. This directly supports broad cable-related manufacturing capability; however, only one quality assurance and quality control inspector is reported.

Customization capabilityThe supplier explicitly offers customization from designs, customization from samples, full customization, minor customization, and flexible customization. This is direct evidence of a broad range of customization services.

Product Q&A

Q:What is ASU cable?

ASU stands for All-dielectric Self-supporting Unitube optical cable, also called mini ADSS. It is a short-span aerial fiber cable specially designed for FTTH last-mile deployment, self-supporting without steel messenger wire.

Q:What span lengths are available?

Standard versions are **80m (ASU-80)** and **120m (ASU-120)**. Do NOT use for span longer than 120 meters.

Q:What fiber counts can you supply?

2, 4, 6, 8, 12, 24 cores are regular. Custom fiber counts available upon request.

Q:What fiber types are optional?

ITU-T G.652D, G.657A1, G.657A2. G.657A2 is preferred for FTTH due to excellent bend resistance.

Q:Is ASU cable metal-free? Why this matters?

Yes, fully all-dielectric with FRP strength members only, no steel. It is lightning-proof and immune to EMI/RFI, no earthing required, safe to run near power lines.
