Reasons for high splicing loss in optical cables
Poor Fiber Cleave: Angled or chipped cleaves prevent proper core alignment. Dirty Fibers: Dust, oil, and residue reduce splice quality. Misalignment: Incorrect positioning of fibers leads to light leakage. Core vs Cladding Mismatch: Using different fiber types without adjustment. Fiber splice loss measures how much signal drops when you join two fiber ends. What is a mechanical splice? What is a fusion splice? Why splice? Fiber splicing is one way to join two optical fibers together so the light energy from one optical fiber can be transferred to another.
