Cleerline's Optipop Cassette-Style Fiber Optic Cleaner effectively removes light oil, dust and other contaminants from fiber connector end-faces without damaging fragile optical lenses and plastic housings. It uses a densely woven, anti-static microfiber cloth that provides over 400 cleanings per reel. Optipop Cleaners are compatible with both 1. 25mm and 2. 5mm ferrule connectors, including SC, FC, ST, MU, LC, MT and MPO/MTP. It features a replaceable tape reel to lower the overall cost per clean -- simply press a built-in lever to expose a fresh section of the cleaning cloth and drag the fiber connector tip across the tape. The Optipop Cassette-Style Fiber Optic Cleaner is designed for both field technicians and data center environments.
