Fiber optic cleaners are perfect for technicians who deal with a high volume of connectors, which can make it difficult to get in between to service and clean. This cleaner is specifically made to be used with LC/APC, LC/UPC, and MU fiber connectors and is the perfect solution to clean the ferrule end faces. An easy pushing motion engages the connector and initiates the cleaner which will remove dirt, oil, and debis which can interrupt the signal.
