1. A method of making an angle polish cut (APC) optical fiber connector comprising:
providing a unitary connector housing defining an interior containing a first ferrule and a second ferrule, each ferrule having a flange and an angle polished cut and being located in an original rotational position, the unitary connector housing comprising a perimeter wall extending 360° about the interior and a contiguous ferrule flange wall extending across the interior, first and second ferrule springs biasing the first and second ferrules forward in the interior of the unitary housing such that the flanges of the first and second ferrules engage the contiguous ferrule flange wall, the unitary connector housing having a contiguous two-ferrule opening through a front end of the unitary connector housing, each of the first ferrule and the second ferrule extending through the contiguous two-ferrule opening such that the first and second ferrules protrude forwardly from the front end of the unitary connector housing;
reaching into the interior of the unitary connector housing through the contiguous two-ferrule opening with a tool to engage the first ferrule;
rotating the first ferrule gripped by the tool in the unitary connector housing about a longitudinal axis of the first ferrule while the second ferrule remains in the original rotational position;
wherein reaching into the interior of the unitary connector housing comprises meshing the tool with structure on a flange of the first ferrule so that the tool and ferrule are engaged for conjoint rotation;
wherein meshing the tool with structure on the flange of the first ferrule comprises inserting a protrusion on the tool into a slot on the flange of the first ferrule.
