The SpecPro 4L fiber optic polisher from krell technologies inc. polishes up to four components simultaneously, including industry-standard connectors, multifiber ferrules, MIL-SPEC termini, optical bundles and bare fibers, and it is suitable for repairing and retropolishing damaged connectors. The compact, portable instrument can be AC- or battery-operated. It offers single-mode performance for R&D, low-volume cable assembly production and field applications. A proprietary independent suspension feature delivers uniform and consistent polishing at each connector position. The polisher interfaces with the company's SpecVision video inspection system for in-line viewing of fiber finishes.
