Reversible polarity MPO fiber optic connector

A fiber-optic connector comprising:

• a connector body including a housing with a top surface and a bottom surface, the top surface and the bottom surface being joined together by two opposing side surfaces of the housing;
• the housing having a top slot and a bottom slot thereupon along a longitudinal axis, the top slot and the bottom slot being provided on the top surface and the bottom surface, respectively;
• a first polarity change element slidably positioned within the top slot;
• and
• a second polarity change element slidably positioned within the bottom slot;
• wherein the first polarity change element is slideable relative to the top slot on the housing and configured to remain within the top slot between a first forward facing surface and a first rearward facing surface on the top surface of the housing, the first forward facing surface and the first rearward facing surface configured to prevent removal of the first polarity change element from the connector housing,
• wherein the second polarity change element is slideable relative to the bottom slot on the housing and configured to remain within the bottom slot between a second forward facing surface and a second rearward facing surface on the bottom surface of the housing, the second forward facing surface and the second rearward facing surface configured to prevent removal of the second polarity change element from the connector housing,
• wherein, in operation, a polarity change of the fiber-optic connector is carried out by sliding the first polarity change element within the top slot toward the first forward facing surface of the housing and retracting the second polarity change element within the bottom slot away from the second forward facing surface of the housing.
