Product Overview

The Quartz Flared Fiber Protection Tube (OD2mm x Wall 0.25mm x Length 12mm) is a precision-engineered micro component designed for bare fiber protection in optical communication devices. Manufactured from high-purity fused silica (SiO2 > 99.99%), it features a unique bell-mouth flared design that combines smooth fiber insertion with secure locking — protecting delicate bare fibers from mechanical damage, thermal stress, and environmental contamination.

Core Design: Flared Bell-Mouth Structure

FeatureBenefit
Flared Inlet (Large End)Guides fiber threading smoothly, eliminating insertion resistance and preventing coating abrasion
Narrow Locking End (Small End)Secures fiber in position, preventing pull-out and bending-induced core fracture
Burr-Free Precision EndsEliminates risk of fiber coating cut from sharp tube edges

Key Features

  • 1100°C High Temperature Resistance: Replaces conventional heat-shrinkable sleeves under extreme thermal conditions, ideal for industrial base stations and power substations
  • Strong Acid & Alkali Resistance: Outstanding chemical durability against corrosive environments, ensuring long-term protection in harsh conditions
  • High Purity Without Metal Precipitation: SiO2 > 99.99% with zero ion leaching, preserving signal integrity in precision optical paths
  • UV Transmittance: Excellent optical clarity for UV-curable adhesive curing and visual fiber inspection
  • Precision Bore & Smooth Inner Wall: Tight diameter tolerance with low-friction inner surface for consistent fiber positioning

Applications

ApplicationDescription
Fiber Connector & Pigtail SleevesPre-installed inside FC/SC/LC connectors to protect fibers against pull stress and bending breakage during plugging/unplugging; ideal for optical modules and transceivers
Fusion Splice Joint ProtectionSealed tube encapsulates fusion splices to isolate damage from high heat, grease and moisture; widely used in high-temperature industrial base stations and power substations
Multi-Core Bundled Fiber ManagementFlared opening gathers multiple bare fibers for neat cable routing; applied in optical splitters and fiber distribution boxes

Competitive Advantages

vs. Heat-Shrinkable Sleeves: Withstands 1100°C vs ~200°C limit; transparent quartz enables visual inspection without sleeve removal; zero outgassing in vacuum or high-temperature environments

vs. Ceramic Ferrules: Lighter weight with comparable hardness; UV-transparent for adhesive curing; precision bore with smoother inner wall finish; more cost-effective for high-volume deployment

vs. Plastic Protection Tubes: Superior thermal stability with no softening or deformation; excellent organic solvent resistance; long-term dimensional stability without yellowing or embrittlement
