The present invention relates to an optical fiber connector arrangement that finds application in the general field of optical interconnection. The optical fiber connector arrangement () comprises a first optical fiber connector () including a first optical fiber () and a counterpart optical fiber connector () including a counterpart optical fiber (); wherein the first optical fiber connector () is configured to mate with the counterpart optical fiber connector (). The first optical fiber () of the first optical fiber connector () has a core diameter Dand a Numerical Aperture NAand the counterpart optical fiber () of the counterpart optical fiber connector () has a counterpart core diameter Dand a counterpart Numerical Aperture NAAt least one of the ratio (DD) or the ratio (NANA) either exceeds 1.15 or is less than 0.85.

Optical fiber connector

The present invention relates to an optical fiber connector that finds application in the general field of optical inter-connection. The optical fiber connector () includes a body () having a bore () configured to receive an optical fiber; an alignment sleeve () that is arranged coaxially with the bore (); an optical fiber () having an end face (); wherein the optical fiber () is arranged within the bore (). At least at the end face () the optical fiber connector includes an optical signature component () having a predetermined optical signature.

Optical fiber connector validation

The appliance includes a brushhead having conductive fiber bristles by which a potential is applied to electrochemically activate a teeth whitening substance, such as peroxide, in the vicinity of the teeth. An impedance appliance system () or an optical appliance system () provides information concerning whether the conductive fiber bristles are adjacent a tooth surface or gum region. The impedance system uses an electrical signal through the fiber to determine the impedance of a circuit which includes the tooth or gum surface, the impedance being different, depending on whether a tooth or gum surface is in the circuit. The optical system generates a light beam which is directed to the mouth surface through a conductive fiber, the color of the returning light indicating whether the surface is a tooth or gum region. If a tooth is determined, the teeth whitening substance is activated at that bristle, while if gum tissue is determined, the teeth whitening substance is not activated at that bristle.
