Abstract
A factory processed and assembled optical fiber arrangement is configured to pass through tight, tortuous spaces when routed to a demarcation point. A connector housing attaches to the optical fiber arrangement at the demarcation point (or after leaving the tight, tortuous spaces) to form a connectorized end of the optical fiber. A fiber tip is protected before leaving the factory until connection is desired.
Claims20
A connector arrangement comprising:
- a ferrule assembly terminating an optical fiber of an optical cable, the ferrule assembly including an optical ferrule and a hub supporting the ferrule, the optical ferrule receiving the optical fiber so that an end of the optical fiber is accessible at an end face of the optical ferrule;
- a front connector housing arrangement, the front connector housing arrangement including a first body defining an interior in which the ferrule assembly is disposed so that the end face of the optical ferrule is accessible through an open front of the first body, the first body including a first portion of a keying arrangement at the interior, the first body also including a first portion of a latching arrangement;
- and
- a rear connector housing arrangement that couples to the front connector housing arrangement, the rear connector housing arrangement including:
- a keying member coupled to the hub of the ferrule assembly in a rotationally fixed position, the keying member having an exterior that includes a second portion of the keying arrangement, the second portion of the keying arrangement being configured to engage the first portion of the keying arrangement in only one rotational orientation to rotationally key the ferrule assembly to the first body;
- an anchor member disposed about the optical fiber, the anchor member being attached to a jacket or strength layer of the optical cable;
- and
- a second body coupling together the keying member and the anchor member, the second body including a second portion of the latching arrangement that is configured to engage the first portion of the latching arrangement of the first body to secure the keying member and the anchor member to the first body.

A connector sub-assembly configured to be moved through a duct, the connector sub-assembly comprising:
- a ferrule assembly terminating an optical fiber of an optical cable, the ferrule assembly including an optical ferrule, a hub supporting the ferrule, and a dust cap mounted about the ferrule, the optical ferrule receiving the optical fiber so that an end of the optical fiber is accessible at an end face of the optical ferrule, the dust cap covering the end face of the optical ferrule;
- a keying member disposed about the optical fiber, the keying member being coupled to the hub of the ferrule assembly in a rotationally fixed position, the keying member including a portion of a keying arrangement at an exterior surface of the keying member;
- an anchor member disposed about the optical fiber, the anchor member being attached to a jacket or strength layer of the optical cable;
- a body coupling to the keying member to hold the keying member at a rotationally fixed location relative to the body, the body also coupling to the anchor member to hold the anchor member at a rotationally fixed location relative to the body, the keying member and the anchor member being carried with the body so that the keying member and the anchor member move axially in unison with the body when the body is moved axially;
- and
- a coil spring disposed about the optical fiber between the hub of the ferrule assembly and the anchor member, the coil spring being disposed within the body to be carried with the body.
