Lanview LFA410 Fiber Protection Sleeve 40 mm

The Lanview LFA410 Fiber Protection Sleeve 40 mm is an essential accessory designed specifically for optical fiber fusion splices. Supplied in a convenient 100-pack, these splice protection sleeves provide dependable mechanical strength and environmental protection at the vulnerable fusion point. Each sleeve functions as a flexible, heat-shrinkable element that significantly reduces its volume when exposed to heat, tightly sealing the spliced fiber. Integrated stainless steel rods offer robust structural rigidity, ensuring the weld area remains fully protected against bending, mechanical stress, and accidental damage during installation and ongoing operation.

Advantages

Using the Lanview LFA410 fiber protection sleeve ensures long-term reliability and stability for optical networks. The durable outer tube shrinks uniformly under heat, creating a tight barrier that effectively shields the delicate fiber fusion from moisture, dust, and various environmental contaminants. The inclusion of a high-grade stainless steel rod reinforces the splice point, preventing accidental breakage or micro-bends that could otherwise degrade signal transmission. With a standardized length of 40 mm and a generous pack size of 100 units, technicians have an ample supply of consistent, high-quality components for efficient and professional network deployments.

Suitable for

• FTTH and FTTx network installations and maintenance
• Data center fiber optic cabling and management
• Telecommunication infrastructure repair and splicing
• Local area network deployments requiring durable fusion protection

When it may not be suitable

This product is not suitable for mechanical splices that do not require heat-shrink protection or fusion welding. Additionally, the 40 mm length may not be compatible with splice trays or enclosures designed exclusively for different sleeve dimensions, such as 60 mm variants.

Key specifications

• Length: 40 mm
• Pack size: 100 pieces
• Reinforcement: Stainless steel rod
• Function: Heat-shrinkable protection for optical fiber fusion splices
• Protection features: Mechanical strength, moisture resistance, and contamination prevention

How to use

Before initiating the fusion splicing process, slide the Lanview LFA410 protection sleeve onto one of the optical fibers. Once the fusion splice has been successfully completed and inspected, carefully position the sleeve centrally over the exposed splice point so that the stainless steel rod provides balanced support along the weld. Transfer the sleeved fiber into a dedicated heat oven or heat-shrink tool compatible with fiber protection sleeves. Apply heat according to the standard operating instructions of your heating tool, allowing the sleeve to uniformly shrink and tightly encapsulate the fiber and reinforcing rod. Allow the sleeve to cool completely before handling or placing it into a splice tray.

What to consider before purchase

• Verify that your fiber splice trays or closures accommodate 40 mm length sleeves
• Confirm that your equipment utilizes fusion splicing methods requiring heat-shrink protection
• Check the quantity requirements for your project to ensure the 100-pack meets your operational needs

Usage recommendations: Always store unused Lanview LFA410 fiber protection sleeves in a clean, dry environment away from direct sunlight and excessive humidity to maintain the integrity of the heat-shrink material and stainless steel components.
