This document specifies the product model, structural parameters, manufacturing length and performance requirements of butterfly optical cables (hereinafter referred to as optical cables), and describes the corresponding test methods, inspection rules, packaging, marking and. FTTH Butterfly Optic Cables are specifically designed to meet the growing demand for high-speed fiber-to-the-home deployments. Their flat, butterfly-shaped structure combines optical fibers with strength members, making them ideal for indoor wiring, drop cable installations, and last-mile network. The invention belongs to the technical field of optical cables, and discloses a butterfly-shaped drop-in optical cable for communication, which has a fitting part (1), a plurality of protection bodies (2), a plurality of butterfly-shaped drop-in units (3), a protective layer (4), The outer sheath. GJYXFHS optical cable is engineered for efficient conduit entry of optical cables, offering robust performance and durability. An additional steel wire strength member is attached to the outer side, followed by extrusion with black low smoke.
