A cleaner is provided for cleaning the end surface area of a ferrule of a fiber optic connector. The system includes an optical detection device, and an ultrasonic detection device, and a conveyance device for transporting the bank note along a defined path proximate the detection devices. Each of the end members is comprised of a truss having an upper wire and a lower wire. Given the same duplexer spacing, a higher band spacing that can be realized with SAW filters is created between transmission and reception band or the corresponding frequency sub-ranges.
