ASI makes ordering Fiber Optics easier with the Universal Fiber Optics System. ASI has eliminated the five-hole/six-pin confusion by offering tubing that accepts both connections. This allows dentist to use both the American 5 Hole type handpieces and/or European 6 pin type handpieces. ASI’s Universal Fiber Optic System includes the power supply, single tubing with bulb, and six-pin adaptor.
