FTTH Drop Cable Fiber Sleeve Suitable for Splicing of drop fiber and drop fiber. Which mainly contains three parts: heat-shrinkable tube, hot-melt tube and stainless steel needle. The Fiber Optic Cable Protection Sleeve is a specially designed optical fiber splice protection element composed of cross-linked polyolefin, heat shrinkable tube and reinforced stainless steel wire. It can improve the mechanical strength of the optical fiber fusion splice, protect the splice, and ensure the reliability of the splicing. Before shrinking the fusion splice protection sleeves, the transparent outer layer can be used to detect whether the light splicing part is connected correctly, so that the optical fiber can be assembled easily and safely, and provide protection. After shrinking, the transmission characteristics of the optical fiber can be maintained. Provide strength and protection.According to the number of reinforcing cores, it can be divided into single pin and double pin Smoove fiber optic splice.
