TB Quartz Capillaries

Name: TB Quartz Capillaries
Brand: Shenzhen Solar Valley Scitech Development Co., Ltd.

TB Quartz Capillaries, made from high-purity fused quartz, are fundamental to optical communication. They offer exceptional inner diameter precision (±0.001mm), ensuring high dimensional accuracy, excellent physical and chemical durability, and superior UV transmission. Designed to precisely position three optical fibers in an isosceles triangular arrangement, these capillaries enable quick curing and bonding with UV adhesive for stable fiber placement. Their fiber-like polishing qualities facilitate the easy attainment of the necessary optical polishing surface for fiber connections, making them suitable for optical connectors, fiber joints, and couplers.

Features of TB Quartz Capillaries

Material: high purity fused quartz, silica (SiO2) content > 99.99%, softening point > 1650℃, high strength, high wear resistance, high transmittance.
Properties: The quartz capillary is melted and drawn at high temperature. The surface is transparent, which eliminates local hidden micro-cracks on the surface. It is not easy to crack and break when dispensing glue to fix the optical fiber, and the dispensing qualification rate is high.
The quartz capillary is a transparent surface with high ultraviolet transmission characteristics. The capillary and 3 isosceles triangular optical fibers can be quickly cured and bonded by ultraviolet adhesive to fix and position the optical fibers.
Environmental Properties: The production process does not use any chemical solvents, and the materials and production process do not contain or involve substances controlled by the European Union.
High dimensional accuracy: Quartz capillary with triangular inner holes are accurately made by CNC wire drawing tower, and optical fiber dimensional tolerance and positioning accuracy are high.
