SB Quartz Capillaries

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

SB Quartz Capillaries are essential for optical communication, crafted from high-purity quartz. They feature a square hole with an inner diameter accuracy of ±0.001mm, ensuring high dimensional positioning accuracy, outstanding physical and chemical properties, and superior UV transmission. Capable of precisely positioning up to four optical fibers, these capillaries facilitate quick curing and bonding with UV adhesive for stable fiber positioning. Their fiber-like polishing characteristics allow for easy achievement of the required optical polishing surface, making them ideal for use in optical connectors, fiber joints, and couplers.

Features of SB 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 4 matrix array fibers or more matrix array fibers can be quickly cured and bonded by ultraviolet adhesive to fix and position the fiber.
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 capillaries of various inner hole shapes and structures are accurately made by CNC wire drawing tower, and optical fiber dimensional tolerance and positioning accuracy are high.
