Patent attributes
A fiber optic adapter, including: a mating retainer; an alignment sleeve received in the mating retainer, a ferrule of a fiber optic connector being adapted to be inserted into the alignment sleeve through an insertion port of the fiber optic adapter; and an adjustment element configured to adjust a circumferential angle of the alignment sleeve relative to the mating retainer to a predetermined circumferential angle and hold the alignment sleeve at the predetermined circumferential angle relative to the mating retainer. The adjustment element may adjust the circumferential angle of the alignment sleeve with respect to the mating retainer to the predetermined circumferential angle, for example, at which the fiber insertion loss of the coupled connectors is minimal, and hold the alignment sleeve at the predetermined circumferential angle. In this way, it may improve the alignment accuracy of the coupled connectors.
