NTT Advanced Technology Corp. is offering the NeoClean-E cleaner, a pen-style optical connector cleaner designed to clean the end faces of in-adapter ferrules. It simplifies the cleaning process because the tube guides the cleaning tip correctly to the sleeve of the connector and applies sufficient pressure on the ferrule end face. It is available in two sizes, 1.25 and 2.5 mm, so it can accommodate multiple fiber optic connector types. It can be used in the field, and each cleaning cycle takes <3 s. The cleaner uses a replaceable cartridge that contains the cleaning section and thread. When the cleaning thread has been completely used, the cartridge is disposed of and replaced with a new one.
