kevlar
Aramid yarn is a superior material for reinforcing optical cables, suitable for ADSS optical cables, non-metallic optical cables, and indoor optical cables. Has special properties such as low density, high tensile modulus, high fracture strength, and low elongation at break; At higher temperatures, it can maintain inherent stability, low shrinkage rate, low creep, and high glass transition temperature; In addition, it has high corrosion resistance, non conductivity, and strong chemical resistance.
Optical cable grease
Fiber optic cable grease is one of the important components of communication optical cables. In order to ensure the sealing of the optical fiber and prevent the infiltration of moisture and water, in addition to filling the gaps of the optical cable with optical cable grease, it is also necessary to apply optical fiber grease on the optical fiber to ensure its good mechanical and optical performance and transmission stability, extend its service life, and improve the product qualification rate.
grating
An optical device composed of a large number of parallel slits of equal width and spacing is called a grating. The commonly used grating is made by carving a large number of parallel scratches on a glass sheet. The scratches are opaque parts, and the smooth part between the two scratches can be transparent, equivalent to a slit. The refined grating is engraved with thousands or even tens of thousands of notches within a width of 1cm. This type of grating that uses transmitted light diffraction is called a transmission grating, and there are also gratings that use reflected light diffraction between two notches. For example, many parallel notches are engraved on a surface coated with a metal layer, and the smooth metal surface between the two notches can reflect light. This type of grating is called a reflection grating.
Fiber optic flange
Fiber optic flange, also known as fiber optic adapter or fiber optic coupler. Fiber optic flange is a device for detachable (movable) connection between optical fibers, and is a connecting component in fiber optic movable connectors. It precisely connects the two end faces of the optical fiber to maximize the coupling of the optical energy output from the transmitting fiber to the receiving fiber, and minimize the impact on the system caused by its intervention in the optical link. The optical fibers are connected by adapters through their internal opening sleeves to ensure the highest connection performance between them. Each pair of optical transceivers needs to be equipped with 2 flanges, which are divided into ST interface, SC interface, and FC interface.
