Branch Off Clip for Fiber Optic Cable Shrinkable Tube: Complete Installation

By Chengdu Focus Infra Materials Co., Ltd.

In outdoor fiber cabling, FTTH, splice closure, and telecom infrastructure projects, stable cable branching and reliable sealing are critical to long-term network performance. The Branch Off Clip for Fiber Optic Cable Shrinkable Tube has become an essential accessory for standardizing cable branching, enhancing sealing, and protecting fiber links from moisture, dust, and mechanical stress.

This guide covers core functions, correct usage, key benefits, and why Chengdu Focus Infra Materials is your trusted partner for high-quality branch off clips.

What Is a Branch Off Clip for Fiber Optic Cable Shrinkable Tube?

A branch off clip (also called fiber optic branch clip, cable branch sealing clip) is a professional accessory designed for fiber cable branching applications with heat shrinkable tubes and splice closures. It securely separates and fixes cable branches, assists heat shrink tubes in forming a tight, waterproof seal, and maintains stable routing in the closure port.

Paired with adhesive-lined heat shrink tubes, it provides environmental sealing for cable joints, effectively preventing water ingress and extending service life in harsh outdoor environments.

Core Functions & Advantages of Fiber Optic Branch Off Clips

1. Stable Cable Branching & Routing

It accurately separates and positions branch cables, avoiding extrusion, bending, or friction inside splice closures. This greatly reduces fiber bending loss and ensures long-term signal stability.

2. Superior Waterproof & Sealing Performance

When used with shrinkable tubes, the branch off clip supports even heat conduction. The hot-melt adhesive layer melts and fills gaps, forming an integrated waterproof seal that meets IP-rated protection requirements.

3. Strong Mechanical Protection

Made of high-strength, corrosion-resistant material, it withstands compression, tension, and outdoor weathering. It protects cable branches from damage during installation and operation.

4. Easy & Efficient Installation

With a user-friendly structure, installers can complete positioning and fixing quickly. It is compatible with most standard heat shrink tubes and fiber splice closures, reducing construction time and labor costs.

5. Wide Compatibility

Suitable for different cable diameters and various closure types. It supports 1-to-2, 1-to-3 branching and meets telecom, FTTH, utility, and railway communication applications.

How to Use Branch Off Clip with Shrinkable Tube?

1. Prepare branch cables and route them through the splice closure port.

2. Install the branch off clip to fix and separate the branch cables.

3. Place the heat shrinkable tube over the branch area and clip.

4. Apply even heat to shrink the tube; the adhesive seals gaps completely.

5. Check sealing and routing to ensure stable, protected branching.
