How to splice an outdoor 4-core fiber optic cable to a terminal box

Splicing a 4-core outdoor fiber optic cable involves careful preparation, precise splicing (mechanical or fusion), and organized routing within a weatherproof termination box to ensure low-loss, durable connections.Step 1: Prepare the Fiber CableStrip the outer jacket: Use a fiber cable stripper to remove the protective outer jacket and any strength members, exposing the individual fiber cores without damaging them .Clean the fibers: Wipe each fiber with lint-free wipes and isopropyl alcohol to remove dust, dirt, or coating residues .Cleave the fibers: Use a high-quality fiber cleaver to create a smooth, perpendicular end face, which is critical for low-loss splicing .Step 2: Choose a Splicing MethodFusion splicing: Aligns and welds the fiber ends using a fusion splicer, producing a permanent, low-loss connection (typically
