Micro Quartz Capillary Tubes for Passive Optical Communication Components

Micro Quartz Capillary Tubes for Passive Optical Communication Components

Micro quartz capillary tubes are precision-engineered components widely used in passive optical communication systems for applications like fiber alignment, splicing, and beam expansion. Here are the key product details:

Material Properties
High-Purity Fused Silica: Excellent optical clarity (UV to IR transmission), low thermal expansion, and high chemical resistance.
Diameter Tolerance: Typically ±0.5 µm for critical dimensions.
Surface Quality: Smooth bore (Ra < 1 nm) to minimize light scattering.

Key Specifications
Inner Diameter (ID): 50 µm to 1,500 µm (customizable).
Outer Diameter (OD): 125 µm to 3,000 µm.
Length: Standard 1–100 mm (longer lengths on request).
Roundness/Circularity: <1% deviation.
Coating Options: Anti-reflective (AR) coatings for specific wavelengths (e.g., 1310 nm, 1550 nm).

Applications in Optical Communications
Fiber Ferrule Alignment: Ensures precise core alignment in connectors.
Fusion Splicing Protectors: Shields spliced fibers in splices/connectors.
Micro-Optic Lenses/Collimators: Acts as a housing or beam-shaping element.
Capillary Splice Systems: Used in passive alignment devices.

Performance Advantages
Thermal Stability: Withstands temperatures up to 1,200°C.
Low Insertion Loss: <0.1 dB in optimized designs.
Hermetic Sealing: Ideal for protecting sensitive optical components.

Compliance & Standards
Telcordia GR-1221/GR-1209 (reliability for telecom environments).
ISO 9001/14001 certified manufacturing.

Customization
Non-standard IDs/ODs, tapered designs, or metallized coatings (e.g., Au, Al) for soldering.

Packaging
Cleanroom-packed in trays or gel-free tubes to prevent contamination.
