CLEP-25-M is a simplified pen type cleaner, which allows the cleaning of the end-faces of fibre connectors and in-adapter ferrules with one simple action. The pen cleaner features a special microfiber tissue that removes all contaminations and secures them. Its antistatic property prevents static load that could bring new contamination after the cleaning. The cleaners are used for a wide range of applications, including cleaning of fiberoptic connector endfaces alone and connected in patchpanels and adapters.
