The Fujikura ALCOA CT-04B is a high-precision fiber cleaver engineered to produce minimal endface angles for low-loss optical fiber splices. This compact, self-contained instrument delivers consistent cleave quality across single-mode and multi-mode fibers, making it essential for telecommunications, data center, and laboratory environments where splice reliability directly impacts network performance.
