Optical fiber with electrical encoding
DCFirst Claim
1. A fiber optic connector for use with a complementary connector, comprising:
- means for holding the end of an optical fiber;
an engagement member, connected to the holding means, configured for positive mechanical and electrical engagement with an engagement portion of the complementary connector so as to maintain the holding means registered to the complementary connector;
a contact element mechanically supported by the engagement member and configured for electrical engagement with a contact portion of the complementary connector; and
means for establishing a defined value of an electrical characteristic between the engagement member and the contact element.

Abstract
A fiber optic connector system. A first connector (25) associated with the fiber (15) includes a fiber holder (40) and a first engagement member. A second complementary connector (30) includes a fiber receptacle (95) and a second engagement member (90). The fiber holder is maintained in a precise position by the second connector when the first and second engagement members engage one another. The second connector may be associated with a radiation source. Associated with the first connector is a contact element (75) electrically coupled to the first engagement member through a network (80) for establishing a defined electrical characteristic therebetween. A second contact element (92, 103) associated with the second connector is normally insulated from the second engagement member and is mounted relative to the second engagement member so that the first and second contact elements make electrical contact with each other when the first and second engagement members are mechanically engaged with each other. Sensing circuitry (32) provides an electrical signal that represents the electrical characteristic between the second contact element and the second engagement member. Thus, when the first connector is engaged with the second connector, the signal represents the defined characteristic. Different type of fibers are provided with different values of this characteristic in the connector.
