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. ## Claims ### Claim at position 1 1-73. (canceled) ### Claim 74 A fiber optic connector assembly, comprising: a fiber optic arrangement configured to be pushed or pulled through a duct, the fiber optic arrangement including: an optical cable defining a longitudinal axis; a ferrule that holds a distal end of an optical fiber extending from a terminated end of the optical cable; a ferrule hub that carries the ferrule; a spring positioned proximal to at least a portion of the ferrule hub along the longitudinal axis; and a protrusion positioned proximal to at least a portion of the ferrule hub along the longitudinal axis and protruding radially away from the longitudinal axis; a proximal housing including an axial slot extending along an entire length of the proximal housing parallel to the longitudinal axis, an opening and latch members; and a distal housing, the latch members of the proximal housing being configured to hold the proximal housing to the distal housing by sliding the distal housing toward the proximal housing along the longitudinal axis, wherein the proximal housing is configured to be inserted over the optical fiber by passing the optical fiber through the axial slot perpendicular to the longitudinal axis and such that the spring is positioned within the proximal housing; and wherein the opening of the proximal housing is configured to receive the protrusion to limit movement along the longitudinal axis of the proximal housing relative to the fiber optic arrangement. ### Claim 75 (depends on 74) The fiber optic connector assembly of claim 74, wherein the protrusion is an alignment member. ### Claim 76 (depends on 75) The fiber optic connector assembly of claim 75, wherein the protrusion includes a ramp and a shoulder. ### Claim 77 (depends on 74) The fiber optic connector assembly of claim 74, wherein the protrusion includes a shoulder. ### Claim 78 (depends on 74) The fiber optic connector assembly of claim 74, wherein the protrusion protrudes from a keying member of the fiber optic arrangement. ### Claim 79 (depends on 78) The fiber optic connector assembly of claim 78, wherein the keying member includes two protrusions protruding radially away from the longitudinal axis. ### Claim 80 (depends on 74) The fiber optic connector assembly of claim 74, wherein the protrusion is positioned distal to the spring along the longitudinal axis. ### Claim 81 (depends on 74) The fiber optic connector assembly of claim 74, wherein the latch members are positioned on opposite sides of a circumference of the proximal housing. ### Claim 82 (depends on 74) The fiber optic connector assembly of claim 74, wherein the latch members have arrow shapes. ### Claim 83 (depends on 74) The fiber optic connector assembly of claim 74, wherein the latch members include ramp surfaces and shoulders. ### Claim 84 (depends on 74) The fiber optic connector assembly of claim 74, wherein the latch members are configured to be received in apertures of the distal housing. ### Claim 85 (depends on 84) The fiber optic connector assembly of claim 84, wherein the latch members include distal facing shoulders. ### Claim 86 (depends on 74) The fiber optic connector assembly of claim 74, wherein the latch members are configured to be received in slots of the distal housing. ### Claim 87 (depends on 84) The fiber optic connector assembly of claim 84, wherein the distal housing includes tapered slits leading from proximal ends of the distal housing to the apertures. ### Claim 88 (depends on 74) The fiber optic connector assembly of claim 74, further comprising a protective arrangement configured to enclose the fiber optic arrangement. ### Claim 89 (depends on 88) The fiber optic connector assembly of claim 88, wherein the fiber optic arrangement is configured to be pushed or pulled through the duct while enclosed in the protective arrangement. ### Claim 90 (depends on 74) The fiber optic connector assembly of claim 74, wherein the proximal housing defines a trumpet shape.
