Fujikura CT-05 SM MM High Precision Single Fiber Cleaver

The Fujikura CT-05 is a high-precision single-fiber cleaver for both single-mode (SM) and multimode (MM) conventional silica optical fibers. This manual tool delivers clean, low-loss cleaves essential for fiber splicing, connector installation, and field termination work. The CT-05 combines cost-effective operation with cleave quality comparable to more expensive instruments, making it a practical choice for labs and field technicians preparing fibers for fusion splicing or mechanical connector assembly.
