Fiber optic snap-on number tubes are labeling sleeves designed to attach directly to cables, allowing easy marking with numbers, letters, or symbols for organized cable management.

Overview

Fiber optic snap-on number tubes are small, durable sleeves that snap onto fiber optic cables to provide clear identification and organization. They are widely used in telecommunications, data centers, and industrial wiring to prevent cable confusion, ensure proper routing, and maintain system reliability .

Types and Features

1. C-Type Snap-On Sleeves

• Designed for 0.9–4mm cable diameters.
• Adjustable and flexible for different wire sizes.
• Can display numbers or letters for easy identification.
• Often used as network cable ID markers . 2. M-Type Snap-On Number Tubes
• Made of UL-qualified POM material with fire resistance (94V-2 rating).
• M-shaped design stabilizes the tube on the cable, preventing flipping.
• Features double-column and double-hole design for neat arrangement of numbers and letters.
• Can display numbers 0–9, letters A–Z, and symbols like + or -.
• Waterproof, non-deformable, and easily combinable for complex wiring routes.
• Equipped with inverted whiskers on the jaws to prevent slipping when clamped onto the wire .

Installation

• Snap-on tubes are tool-less and can be attached directly to cables.
• They can be mounted between clips, on panels, or along cable trays.
• Some types include adhesive pads or clip-in bases for additional stability .
• The design allows for easy removal or repositioning without damaging the cable.

Applications

• Telecommunication cabinets and data centers for organized fiber routing.
• Industrial wiring where multiple cables require clear identification.
• Network maintenance to quickly identify and trace cables.
• Complex installations using multiple colored markers to indicate different routes or functions .

Summary

Fiber optic snap-on number tubes provide a reliable, reusable, and organized solution for labeling fiber optic cables. Choosing between C-type or M-type depends on cable diameter, marking requirements, and environmental conditions. Their durable materials, easy installation, and clear marking capabilities make them essential for professional cable management.
