1. A fiber optic connector having a boot, a crimp body, and a housing having at least two optical fibers therein, the fiber optic connector comprising:
a front end opening in the housing, the housing having a pair of short sides forming a top and a bottom and a pair of long sides joining the top and the bottom, the at least two optical fibers spaced apart between the top and the bottom formed by the pair of short sides, a separation between the top and the bottom is more than a separation between individual ones of the pair of long sides;
the crimp body positioned rearward of the front end of the housing, the crimp body having a rear portion; and
the boot receiving the rear portion of the crimp body and having a front extension, the front extension extending towards the front end of the housing and attached to the housing forward of a center portion of the boot, wherein the crimp body and the boot each have a respective contiguous longitudinal opening to accommodate the at least two optical fibers having ends terminated forward of the front end opening of the housing, and
wherein the longitudinal opening extends through a back portion of the boot rearward of the center portion of the boot;
wherein the front extension is located on the top of the housing;
wherein the fiber optic connector is configured to mate with an adapter having a keyway along a first wall of the adapter, the front extension configured to be received in the keyway when the fiber optic connector is mated with the adapter;
wherein the boot is configured to be displaced rearward relative to the at least two optical fibers to actuate the optical fiber connector for extraction from the adapter, the front extension configured to move rearward in the keyway relative to the at least two optical fibers when the boot is displaced rearward to actuate the optical fiber connector for extraction from the adapter.
