What is ASU80 Fiber Optic Cable?
ASU80 is a lightweight, self-supporting, all-dielectric Optical Fiber Cable designed for aerial deployment in spans of up to 80 meters, commonly used in urban backbone, backhaul, and FTTH access networks.
ASU80 belongs to the ASU (Aerial Self-Supporting, Single-tube) cable family, a cost-optimized alternative to traditional ADSS cables. The "U" in ASU stands for "single," referring to the single loose tube that makes up the cable's core. This single loose tube contains the optical fibers (typically 2 to 24 cores) and is filled with water-resistant gel to protect against moisture. The core is reinforced with two parallel FRP (Fiber Reinforced Plastic) strength members, making the cable completely dielectric—meaning it contains no metallic components and does not conduct electricity.

FRP strength members – Two parallel non‑metallic FRP rods, offering tensile strength and stiffness for self‑supporting aerial installation.
Rip cord – Nylon thread for slitting the jacket lengthwise to access the inner tube.
PBT loose tube – Hard PBT tube housing fibers, with crush resistance, moisture protection, and mechanical isolation.
Fiber jelly – Water‑blocking thixotropic gel filling the tube, preventing water ingress and cushioning against micro‑bending.
Optical fibers – Single‑mode or multi‑mode, carrying signals; typical count 2 to 24 fibers.
Benefits of ASU80 Mini ADSS cable
Excellent tensile strength and crush-resistance
Two parallel FRP strength members and a PBT loose tube enable the cable to withstand aerial installation tension and external crushing, ensuring fiber integrity during construction and long-term use.
Compact, easy-to-access design for simple installation and handling
The flat, compact structure combined with a rip cord allows on-site stripping without special tools, providing quick fiber access and significantly reducing installation time and difficulty.
All-dielectric loose tube construction immune to EMI, UV‑protective outer jacket
Fully non-metallic design eliminates electromagnetic interference risks, making it safe for installation near power lines. The UV-resistant PE jacket prevents aging under prolonged sunlight exposure.
Optimized fiber counts (4. 6. 8. 12. 24) to minimize deployment costs
Offers the most common low fiber counts tailored for FTTx and access networks, avoiding excess fiber waste while keeping material and inventory costs low.
Engineering Applications ASU80 Mini ADSS cable
Urban FTTH & Access Networks
ASU80 cables are ideal for Fiber-to-the-Home (FTTH) deployments and access networks in urban areas. Their self-supporting design allows for spans up to 80 meters, perfectly matching the typical 40-meter distance between urban utility poles. The all-dielectric construction simplifies installation and eliminates grounding concerns.
This lightweight and compact cable enables rapid, cost-effective rollout of high-speed data, voice, and video services directly to residential and business users.
Rural Broadband & Long-Haul Trunking
Designed for use in both urban and rural networks, the ASU80 cable's robust performance makes it well-suited for long-distance trunk lines and bridging the digital divide in remote areas. Its UV-resistant PE outer sheath can withstand various outdoor weather conditions.
With low attenuation and high bandwidth, it maintains high-quality signal transmission over long-distance LAN backbones, serving as an economical solution to replace GYFTY cables in certain scenarios.
High-Voltage Power Line Communication
ASU80 is a fully dielectric, non-metallic cable, making it ideal for communication routes on overhead high-voltage power transmission systems. The all-dielectric material eliminates induced voltage and the risk of electrical discharge, ensuring safe operation in high EMI environments.
Its self-supporting system with FRP strength members also makes it suitable for lightning-prone zones and long-distance overhead lines, providing reliable communication for power grid monitoring and control.
Duplex (Aerial & Pipeline) Installations
The cable's versatile design is certified for both aerial and ducted pipeline laying methods. Its compact, lightweight nature facilitates handling and installation in confined spaces like pipelines while also saving on transportation costs.
Filled with a special water-blocking compound, ASU80 guarantees critical fiber protection against moisture in underground ducts. This dual-use capability allows for seamless outdoor distribution and local area network communication.

ASU80 Mini ADSS cable Selection Guide
Choose ASU80 (Mini ADSS) for short‑span aerial applications (≤80 m) in urban utility pole networks, FTTH access, or medium/low‑voltage (≤35 kV) distribution lines. Its compact, lightweight design (≈40% lighter than ADSS) and single‑loose‑tube construction make it the most economical choice for low‑core‑count (≤12 cores) deployments where span is short and hardware costs must be minimized. Best for pole‑to‑pole drops in residential areas.
Choose ADSS for long‑span (≤200 m) aerial routes, especially near high‑voltage power lines (10 kV to 1000 kV+). Its double‑sheath, aramid‑reinforced structure handles extreme spans, harsh weather, and high‑voltage environments without grounding. Ideal for river crossings, mountainous terrains, and utility backbone networks. However, it carries the highest material and hardware costs.
Choose AS Cable for medium‑span (80‑150 m) urban/metro backbone, backhaul, and campus interconnection where fiber counts up to 144 cores are required but high‑voltage compatibility is not needed. It offers a balance between cost and capacity, with S‑Z stranded multi‑tube design and moderate installation complexity – suitable for general aerial self‑supporting routes on communication poles.
Quick summary:
Short span, low cost, low core count (≤12) → ASU80
Long span, high voltage, high core count → ADSS
Medium span, medium cost, high core count (≤144) → AS Cable
