Description

Technical Field

[0001] The invention relates to an optical cable pigtail for on-site non-melting connection. Background Art

[0002] Optical cable pigtail refers to an optical fiber connector with a section of optical fiber. In the current optical communication connection, the optical cable pigtail needs to be fused with other optical cables and optical fibers through a fusion splicer to make an optical fiber connector. The optical signal is transmitted by docking or connecting with other optical fiber connectors through an optical fiber adapter. This is a traditional optical communication connection method that is currently widely used. It requires expensive fusion splicers and higher skills to achieve optical fiber connection. The operation is cumbersome and cannot be popularized or applied to the public. At the same time, it is not suitable for on-site wiring in high places, small spaces, the wild, and future large-scale smart cities such as 5G, which hinders the further application of optical fiber. Therefore, we invented an optical cable pigtail that can be connected on-site without fusion. No expensive equipment or special skills are required. The termination and connection of optical fibers on site can be achieved through very simple operations. Summary of the invention
