Optical fiber protection tube Electro Base FO-PTUB-45-1FL — 45 mm length, 2.0 mm diameter

Electro Base FO-PTUB-45-1FL is a protection tube for optical fiber with a length of 45 mm and an outer diameter of 2.0 mm. It is designed to protect fibre end sections and splices from mechanical damage and contamination, providing a compact and rigid sleeve that supports and shields the fiber in tight spaces. The tube is intended for use within splice closures, distribution boxes and equipment cabinets where localized reinforcement of fiber joints is required.

Advantages

The protection tube offers a straightforward method to guard fiber joints and end sections without adding significant bulk. Its 45 mm length and 2.0 mm diameter balance flexibility and rigidity to fit common splice and termination applications. The tube reduces the risk of microbending and protects adhesive or heat-shrink splice areas from dirt and incidental contact, helping to preserve optical performance over time.

Suitable for

• Protection of single fiber splices and pigtail terminations
• Use inside splice closures, distribution boxes and patch panels
• Reinforcement of fiber end sections during routing and installation

Key specifications

• Length: 45 mm
• Outer diameter: 2.0 mm
• Type: protection tube for single optical fiber
• Function: mechanical protection and contamination shielding for splices and fiber ends
• Application environment: indoor enclosures, cabinets and splice trays

How to use

Slide the protection tube over the prepared fiber or splice sleeve so that it fully covers the splice or reinforced end section. Center the tube over the splice area and, if required, secure it within the splice tray or closure using the tray’s retention features or with a small amount of compatible adhesive. Ensure that no excessive bending occurs at the tube ends and that the fiber routing maintains the minimum bend radius specified for the fiber type.

Usage recommendations

Store tubes in a clean, dry environment prior to installation. Inspect the tube and surrounding area for debris before application. Do not apply excessive heat or mechanical force that could deform the tube or damage the fiber.
