1. A fiber optic connector including:
an integrally formed connector housing having a single piece construction, the connector housing including a first end and a second end, the connector housing including a connector housing axial passage that extends from the first end of the connector housing to the second end of the connector housing;
a ferrule, the ferrule having a first end and a second end, the first end of the ferrule extending beyond the first end of the connector housing, the second end of the ferrule abutting an annular shoulder of the connector housing and secured to the first end of the connector housing, the ferrule including a ferrule axial passage that extends from the first end of the ferrule to the second end of the ferrule, wherein the ferrule axial passage is coaxially arranged with the connector housing axial passage;
an end cap, the end cap including a first end and a second end, the first end of the end cap secured to the second end of the connector housing, the end cap having an end cap axial passage that extends from the first end of the end cap to the second end of the end cap, wherein the end cap axial passage is coaxially arranged with the connector housing axial passage, wherein a first end portion of the end cap fits over a cylindrical second end portion of the connector housing having a diameter D3, and a second end portion of the end cap extending between the second end and an inner annular shoulder of the end cap has a length L1 extends away from the second end of the connector housing, wherein the length L1 is less than the diameter D3;
wherein the end cap axial passage has an end cap minimum diameter D1, wherein the second end of the connector housing has an internal diameter D2, wherein the internal diameter D2 of the second end of the connector housing is greater than the end cap minimum diameter D1.
