PA-3000 ADSS Wedge Anchor Clamp for 8–12mm Cable

As aerial fiber optic networks continue to expand, reliable cable anchoring hardware plays a critical role in maintaining network stability, cable tension, and long-term installation performance. For ADSS (All-Dielectric Self-Supporting) optical fiber cables, the anchor clamp must provide sufficient mechanical strength while securely gripping the cable without damaging its outer jacket.

JERA LINE's PA-3000 ADSS Wedge Anchor Clamp is designed specifically for this purpose. Also known as an ADSS tension clamp or wedge-type anchor clamp, the PA-3000 provides a practical solution for securing round ADSS cables on overhead telecommunication lines.

In our latest installation video, we demonstrate how the PA-3000 is assembled and installed, showing its simple structure, tool-free operation, and self-adjusting wedge design.

What Is an ADSS Wedge Anchor Clamp?

An ADSS anchor clamp is a mechanical fitting used to anchor and tension ADSS fiber optic cables on poles and other overhead support structures.

Unlike traditional metal cable grips, a wedge-type anchor clamp uses a specially designed wedge mechanism to grip the cable. When the cable is tensioned, the wedge automatically increases its gripping force, helping keep the cable securely positioned.

The PA-3000 is designed for 8–12 mm diameter ADSS cables and is suitable for overhead telecommunications applications, including FTTH, FTTx, GPON, CATV, and metropolitan access networks. JERA specifies a maximum span of approximately 100 meters for the intended application and an MBL (Maximum Breaking Load) of 8.0 kN.

Key Features of the PA-3000

1. Tool-Free Installation

One of the most important advantages of the PA-3000 is its tool-free installation design.

The installer does not need a dedicated tensioning tool to secure the cable in the clamp. The cable can be positioned inside the clamp and secured through the wedge mechanism.

This helps simplify field installation and can reduce installation time, particularly when contractors need to deploy large quantities of ADSS cable hardware.

For telecom contractors and network operators, faster installation can translate into lower labor costs and improved project efficiency.

2. Self-Adjusting Wedge Design

The PA-3000 uses self-adjusting wedges to grip the ADSS cable.

As the cable is subjected to tensile loading, the wedge mechanism helps maintain the cable's position inside the clamp. This provides a secure anchoring solution without requiring excessive manual adjustment.

The self-adjusting structure also makes the product easier for installers to operate in outdoor working environments.

3. Cable-Friendly Grip

ADSS cables contain optical fibers that need to be protected from excessive mechanical stress. Therefore, an anchor clamp should provide sufficient holding force without unnecessarily damaging the cable jacket.

The PA-3000 uses an extended wedge structure designed to provide a smoother gripping transition and help protect the cable during installation and operation.

This cable-friendly design is particularly important for aerial fiber networks where the cable may experience continuous environmental loads such as wind, temperature changes, and ice.

4. Stainless Steel Bail

The PA-3000 is equipped with a stainless steel bail, providing a strong and corrosion-resistant connection between the clamp and the supporting hardware.

The open bail design also makes it convenient to install the clamp onto compatible pole brackets, hooks, and other aerial line fittings.

JERA's ADSS anchor clamp range uses stainless steel and UV-resistant polymer components to provide mechanical strength and resistance to outdoor environmental conditions.

5. Fast Installation with an Open Bail

The open bail is another practical feature for field installation.

Instead of requiring the installer to completely disassemble the supporting hardware, the clamp can be attached to a compatible hook or bracket through the open bail structure.

This can be particularly useful for maintenance work, network expansion, and rapid deployment of aerial communication lines.

6. Anti-Drop-Off Design

The PA-3000 incorporates an anti-drop-off design to help keep the wedge components properly positioned during installation.

This is especially useful when technicians are working on poles or elevated structures, where small components can be difficult to handle.

The design helps make the installation process more controlled and convenient.

The above specifications are based on JERA LINE's current PA-3000 product information.

How Does the PA-3000 Work?

The working principle of the PA-3000 is straightforward.

First, the ADSS cable is positioned inside the clamp body. The cable is then secured by the wedge components. Once the clamp is connected to the appropriate pole bracket or hook, the cable tension causes the wedge system to grip the cable securely.

The basic installation process can be summarized as:

Step 1 – Open the Clamp

Open the stainless steel bail and prepare the clamp for cable installation.

Step 2 – Insert the ADSS Cable

Place the 8–12 mm ADSS cable into the designated gripping area of the clamp.

Step 3 – Position the Wedge

Position the self-adjusting wedge correctly around the cable.

Step 4 – Secure the Bail

Connect the stainless steel bail to the appropriate pole bracket or hook.

Step 5 – Check the Installation

Verify that the cable is correctly positioned and that the wedge and bail are securely installed.

Because the clamp is designed for tool-free installation, the process can be completed quickly without additional specialized installation equipment.

Where Is the PA-3000 Used?

The PA-3000 is designed for outdoor aerial telecommunications applications.

Typical applications include:

•  FTTH network construction
•  FTTx access networks
•  GPON networks
•  CATV networks
•  Metropolitan fiber networks
•  Aerial ADSS cable routes
•  Pole-to-pole fiber optic installations
•  Last-mile telecommunications infrastructure

It can be used at intermediate poles and other suitable aerial support points where the ADSS cable needs to be securely anchored. JERA specifies the PA-3000 for ADSS cables with diameters from 8 to 12 mm.

Why Cable Protection Matters in ADSS Installation

ADSS cables are designed to be self-supporting, meaning they do not rely on a metallic messenger wire for mechanical support. Consequently, the cable anchoring system must handle the mechanical loads generated by the aerial span.

However, applying excessive or concentrated pressure to the cable can potentially affect the cable jacket and the optical fibers inside.

This is why the design of the gripping area is important.

The PA-3000 combines a self-adjusting wedge mechanism with an extended body/wedge structure to provide a secure grip while helping minimize unnecessary cable jacket stress. JERA specifically lists "no cable jacket damages" and an extended body length for better attenuation of fiber cable among the product features.

Mechanical Reliability and Testing

For aerial cable hardware, mechanical strength is one of the most important performance characteristics.

JERA conducts tensile strength testing on its cable hardware to evaluate the ability of products to withstand mechanical loads. The company's internal laboratory also conducts various product-related tests, including tensile, UV-resistance, and corrosion-related testing.

The PA-3000 has a specified 8.0 kN Maximum Breaking Load, providing a clear mechanical performance reference for cable installation planning.

PA-3000: A Practical Choice for Aerial ADSS Networks

A good ADSS anchor clamp needs to achieve a balance between mechanical strength, cable protection, installation efficiency, and environmental durability.

The PA-3000 combines these requirements in a compact wedge-type design:

•  8–12 mm ADSS cable compatibility
•  8.0 kN MBL
•  Tool-free installation
•  Self-adjusting wedges
•  Stainless steel bail
•  Open-bail design
•  Anti-drop-off structure
•  Cable-friendly gripping design
•  Suitable for outdoor aerial applications
•  Designed for spans up to 100 meters

For contractors, distributors, and telecommunications network operators looking for an efficient anchoring solution for medium-span ADSS deployment, the PA-3000 provides a simple and reliable option.
