Application areas

Fiber connection and fixation: used for bonding and sealing of fiber optic connectors to ensure the stability and reliability of connectors and reduce signal attenuation. It can also be used for fiber coating, coating a layer of wetting glue on the surface of the fiber to protect the fiber from damage by the external environment.

Optical device manufacturing and packaging: When manufacturing various optical devices, such as wavelength division multiplexers, optical switches, optical attenuators, etc., optical communication glue is required for bonding and fixing. For the packaging of optical modules, such as To-can packaging and BOX packaging, glue can provide good sealing performance and mechanical protection.

Optical chip bonding: In the bonding process of optical chips and carriers, substrates, etc., optical communication glue can ensure good electrical connection and mechanical stability between chips and other components, while meeting the requirements of optical chips for high precision and low stress.

Optical path system construction: When constructing an optical path system, such as the connection between optical fiber arrays and optical waveguides, the coupling of lenses and optical fibers, etc., optical communication glue can be used to fix and adjust the position of optical components to ensure the accuracy and stability of the optical path.

Advantages

Excellent optical performance: With high light transmittance, it can reduce the loss of light during transmission and ensure the efficient transmission of optical signals. Some glues can also achieve refractive index matching to avoid refraction and reflection of light at the interface of different media and improve the efficiency of light transmission.

Good bonding performance: It has excellent bonding effect on materials such as optical fiber, metal, glass, ceramic and most plastics, and can firmly bond optical components and parts of different materials to ensure the reliability and stability of the connection. It is not easy to loosen or fall off in long-term use.

Good curing characteristics: Many optical communication glues have fast curing speed and can reach high strength in a short time, improve production efficiency, and are suitable for large-scale automated production. At the same time, some glues can be cured at room temperature without high temperature heating or complex curing equipment, which reduces production costs and process difficulties.

High chemical stability: It can resist the erosion of various solvents and chemicals, and can maintain stable performance in different chemical environments and harsh working conditions. It will not deteriorate, degrade or affect the bonding effect due to contact with chemicals.
