ABSTRACT:
Polarization of the optical fibers (24, 32) of pin-and-socket-type optical fiber termini is provided by extending a sleeve (44) around an optical fiber terminus (15, 26), positioning the optical fiber terminus in a body (11, 12) with the sleeve (44) and body having means for positioning the sleeve (44) in predetermined rotational position, then rotating the optical fiber terminus (15, 26) until its fiber (24, 32) achieves a known polarization, and bonding the fiber and sleeve together by an adhesive (57). The terminus (15, 26) and sleeve (44) may be removed from the body (11, 12) and placed in an optical fiber connector (64, 67) by positioning the sleeve in a known rotational position relative to the connector, which will cause the optical fiber to have a predetermined polarization in the optical fiber connector.
