ASU Fiber Optic Cable
ASU Fiber Optic Cable (All-Dielectric Self-supporting Unitube Cable) is a specialized aerial fiber optic solution engineered for overhead installation without the need for additional steel messengers or support structures. Also commonly known as Mini ADSS, this cable features a compact, all-dielectric design that delivers exceptional performance in short-span aerial applications.
Key Applications
FTTx Last-Mile Connectivity – ASU cable is widely deployed in FTTH and FTTB projects for the final overhead segment from distribution boxes to end-user premises, with spans typically within 120 meters.
Rural and Remote Area Networks – With poles spaced 90–100 meters apart in rural settings, ASU 100 provides an economical and lightweight solution for connecting underserved communities.
Urban and Suburban Utility Pole Networks – In densely spaced urban environments where poles average 40 meters apart, ASU 80 offers easy installation with minimal visual impact.
Infrastructure Crossings – ASU 120 is ideal for longer spans across roads, rivers, and bridges where poles are spaced further apart.
Electromagnetic Interference-Prone Areas – The all-dielectric construction makes ASU cable suitable for installation in lightning-prone regions and areas with high electromagnetic interference.
Core Advantages
Lightweight and Compact Design – With cable diameters ranging from 6.2 mm to 8.0 mm and weights as low as 40 kg/km, ASU cables impose minimal additional load on utility poles and enable faster, more cost-effective deployment.
All-Dielectric Construction – The complete absence of metallic components eliminates the risk of electrical interference, provides superior lightning protection, and enhances overall safety when installed near power lines.
Exceptional Environmental Durability – UV-resistant polyethylene sheathing, water-blocking gel compounds, and moisture-proof construction ensure reliable performance in temperatures ranging from -20°C to +65°C, with a service life exceeding 30 years.
High Tensile Strength – FRP strength members deliver short-term tensile strength up to 1500 N (ASU 120), providing robust mechanical performance while maintaining cable flexibility.
Cost-Effective Alternative – As a more economical alternative to full-scale ADSS cables for short-span applications, ASU reduces both material costs and installation complexity without compromising performance.
Comprehensive Compliance – 100% factory-tested cables with CE, ISO, and Anatel certifications guarantee quality and reliability.

FAQ
Q1: What does ASU stand for in fiber optic cables?
A: ASU stands for All-Dielectric Self-supporting Unitube Cable. It is a fiber optic cable specifically designed for overhead installation, allowing direct suspension between utility poles without relying on separate steel strands or support structures.
Q2: What is the difference between ASU and ADSS cables?
A: The primary difference lies in the span length. ASU cables are designed for shorter spans of 80–120 meters and use FRP as reinforcing material, making them lighter and more compact. ADSS cables support longer spans (up to 200+ meters) and typically use aramid yarn (Kevlar) reinforcement, resulting in a heavier and larger-diameter cable.
Q3: What installation methods are compatible with ASU cables?
A: ASU cables are designed for aerial self-supporting installation using smaller pre-formed fittings. Their lightweight design enables faster deployment compared to heavier long-span cables. The cables can be directly suspended on utility poles and are also suitable for transitioning to conduit in FTTH last-mile applications.
Q4: Is ASU cable suitable for harsh environmental conditions?
A: Yes. ASU cables feature UV-resistant polyethylene sheathing, water-blocking gel compounds, and moisture-proof construction. They operate reliably in temperatures from -20°C to +65°C and resist moisture, UV radiation, and temperature fluctuations. The all-dielectric construction also provides excellent protection against lightning and electromagnetic interference.
Q5: What fiber counts and span options are available?
A: ASU cables are available with 2 to 24 fiber cores in three span configurations: ASU 80 (up to 80 meters), ASU 100 (up to 100 meters), and ASU 120 (up to 120 meters). Fiber options include G.652D, G.655, and multimode varieties. Custom configurations are available upon request.
