1. A fiber optic plug comprising:
- a fiber optic connector comprising a connector housing and a plug ferrule least partially disposed within the connector housing and capable of being mounted upon an end portion of at least one optical fiber; and
a plug body extending lengthwise between a first end and a second end, the first end opposed from the second end, and having a shroud proximate the first end thereof, the shroud defining a pair of openings on opposite sides thereof, the openings extending lengthwise from at least a medial portion of the shroud to the first end of the plug body, wherein the fiber optic connector is disposed within the plug body such that the plug ferrule is accessible within the shroud via the first end of the plug body; and
wherein the lengthwise extending plug body defines a longitudinal axis, and wherein the fiber optic connector is disposed in a fixed position with respect to the plug body relative to rotation about the longitudinal axis such that the openings defined by the shroud are aligned with the plug ferrule; and
wherein the plug body further comprises a shaft proximate the shroud; and
a collar disposed upon the shaft such that travel of the collar in the lengthwise direction is limited while permitting rotation of the collar about the longitudinal axis relative to the shaft.

Abstract
A relatively small fiber optic plug is provided to facilitate pulling of the fiber optic plug and an associated fiber optic cable through small passageways. The fiber optic plug may include a shroud that protects the fiber optic connector and that may further define at least one opening, and preferably a pair of openings. The openings are sized to receive portions of an adapter sleeve once the fiber optic plug is mated with a fiber optic receptacle. The fiber optic plug may also include a cap mounted upon and adapted to swivel relative to the remainder of the fiber optic plug to serve as a pulling grip during installation of the fiber optic cable. Further, the fiber optic plug may include a crimp band that is mechanically coupled to both the fiber optic cable and the plug body in order to isolate the fiber optic connector from torque otherwise created by forces to which the fiber optic cable is subjected.

10. A fiber optic plug comprising:
-
a fiber optic connector comprising a connector housing and a plug ferrule at least partially disposed within the connector housing and capable of being mounted upon an end portion of at least one optical fiber; and
a plug body extending lengthwise between a first end and a second end, the first end opposed from the second end, and having a shroud proximate the first end thereof, the shroud defining a pair of openings on opposite sides thereof, the openings extending lengthwise from at least a medial portion of the shroud to the first end of the plug body, wherein the fiber optic connector is disposed within the plug body such that the plug ferrule is accessible within the shroud via the first end of the plug body; and
wherein the shroud defines a lengthwise extending groove for receiving a corresponding alignment member of a fiber optic receptacle in order to align the fiber optic plug with the fiber optic receptacle.
