Using a high-precision cleaver, you want to cut the fiber so that its end face is perfectly flat and perpendicular—ideally at a 90-degree angle. This fiber optic splicing technique involves the precise alignment of two fiber optic cables, held in place by a self-contained assembly rather than a permanent bond. A mechanical splice is designed to hold two fiber cables in a way that allows light to pass through seamlessly, with a typical loss. Learn how to splice fiber optic cable step by step in this complete guide! In this video, you'll see the full fiber splicing process — from fiber preparation, cleaving, and fusion splicing to final testing. All students and instructors must wear safety glasses in this lab. Safely dispose of all fiber scraps and cables after use. Whether repairing a broken cable or extending a fiber run, fiber optic splicing ensures light signals travel.
