Optical fiber connector protection tube, electro base FO-PTUB-45, length 45 mm

The electro base Optical fiber connector protection tube FO-PTUB-45 is a 45 mm protection sleeve designed to shield exposed fiber connectors and pigtails during storage, transport and installation. It provides a compact mechanical barrier around connector ferrules and short fiber stubs to reduce the risk of bending, abrasion and contamination. The protection tube simplifies handling of fiber ends in patching, splicing and temporary storage scenarios while helping to maintain connector integrity.

Advantages

The protection tube delivers straightforward mechanical protection in a lightweight, durable sleeve that fits common connector types. Its 45 mm length balances coverage and compactness, making it suitable for use in equipment racks, bags and splice trays. The design reduces accidental fiber bending and abrasion, and it helps keep connector endfaces cleaner by limiting direct contact. The product is easy to apply and remove, supporting efficient field and workshop workflows.

Suitable for

• Short-term protection of exposed connectors and pigtails during transport
• Temporary covering of fiber ends while preparing for splicing or termination
• Storage of spare connectors in splice trays, cases or cabinets
• Use during on-site maintenance to prevent mechanical damage

Key specifications

• Length: 45 mm
• Function: mechanical protection against bending and abrasion
• Primary use: protection of exposed optical fiber connectors and pigtails
• Compatibility: intended for common connector ferrule sizes and standard pigtails
• Form factor: compact protection sleeve for easy handling and storage

How to use

Slide the protection tube over the exposed connector or pigtail until it covers the ferrule and a portion of the fiber stub. Ensure the tube seats comfortably without forcing or compressing the connector. For removal, pull the sleeve off gently, taking care not to touch the connector endface. Use the sleeve during transport, storage or between working steps to reduce handling-related contamination and mechanical stress.

Usage recommendations

Store protection tubes in a clean, dry container to avoid debris transfer to connector endfaces. Inspect sleeves for damage before use and replace any that are deformed. Do not use the sleeve as a substitute for permanent connector strain relief; employ appropriate boots, splice protectors or cable management hardware for long-term installations.
