12. The fiber optic connector assembly of claim 1 , wherein the strain relief boot is disposed entirely rearward of the inner housing, and wherein an axial length of the strain relief boot is at least as long as an axial length of the inner housing.
13. The fiber optic connector assembly of claim 1 , wherein at least a portion of an inner wall of the strain relief boot circumferentially surrounds the longitudinal axis, the portion of the inner wall being circumferentially uninterrupted.
14. The fiber optic connector assembly of claim 1 , wherein the socket is a socket in a fiber optic adapter.
15. The fiber optic connector assembly of claim 1 , wherein a tapered axial region of the strain relief boot is radially narrower than at least one radial dimension of the outer housing.
16. The fiber optic connector assembly of claim 15 , wherein the tapered axial region of the strain relief boot is radially narrower than all radial dimensions of the outer housing.
17. The fiber optic connector assembly of claim 1 , wherein the strain relief boot is adapted to be flexed away from the longitudinal axis of the connector within the inner housing.
18. The fiber optic connector assembly of claim 1 , wherein the outer housing is axially spring loaded.
19. A fiber optic connector assembly, the assembly having a mated configuration and a non-mated configuration, comprising:
a socket including first locking features; and
a fiber optic connector having a longitudinal axis extending from a front to a back of the connector, the connector including second locking features, an inner housing supporting a ferrule, an outer housing that moves axially relative to the inner housing, and a strain relief boot;
wherein in the mated configuration a forward portion of the outer housing is housed in the fiber optic socket such that the second locking features lockingly engage the first locking features;
wherein the outer housing is operably coupled to the strain relief boot such that the outer housing and the strain relief boot axially move together relative to the inner housing; and
wherein in the mated configuration axial rearward movement of the strain relief boot causes the outer housing to engage and flex resilient latch arms disposed in the socket to disengage the first locking features from the second locking features.
20. The fiber optic connector assembly of claim 19 ,
wherein the first locking features include projections defined by the resilient latch arms; and
wherein the second locking features include catches protruding from opposing sides of the inner housing and notches positioned rearward of the catches, the notches being configured to receive the projections when the assembly is in the mated configuration.
21. The fiber optic connector assembly of claim 19 , wherein in the mated configuration axial rearward movement of the strain relief boot causes the outer housing to spread apart the resilient latch arms disposed in the socket to disengage the first locking features from the second locking features.
22. A fiber optic connector assembly, the assembly having a mated configuration and a non-mated configuration, comprising:
a socket including one or more first locking features; and
a fiber optic connector having a longitudinal axis extending from a front to a back of the connector, the connector including one or more second locking features, an inner housing supporting a ferrule, an outer housing that moves axially relative to the inner housing, and a strain relief boot;
