What kind of adhesive is best for fiber optic patch cords
The FOC Termination Epoxy Matrix and UV Curable Optical Adhesive or Fiber Optic Coatings Matrix offer these properties in a comparison format for each material option. The use of an inappropriate material or incorrect application is a direct source of reliability and quality. Optical Clarity and Transmission: The adhesive must be perfectly clear and highly transparent across the specific wavelengths of light transmitted through the fiber. Any haze, yellowing, or impurities will absorb or scatter light, leading to unacceptable signal loss (attenuation). The FOC Termination Epoxy. Adhesives for fiber optic components that perform well on glass, metal, ceramic and most plastic substrates provide excellent chemical and solvent resistance. They also can act as an electrical insulator and may be used in high-strength optical alignment applications. Epoxies are thermosetting plastics that remain stable over time and can be tailored for specific applications because they can be formulated for different viscosities, operating temperatures, and cure times. Some adhesives may degrade or lose their bonding.
