The fiber optic transition assembly has a housing with a front opening and an internal passageway that is defined by a wall and a narrow region. The housing is adapted to receive epoxy adhesive. The fiber optic transition assembly has a boot that is positioned at least partially inside the housing for receiving the multi-fiber cable to provide strain relief to the plurality of optical fibers extending therethrough. The fiber optic transition assembly has a plug supported by the boot and retained by the housing to prevent epoxy adhesive from entering the multi-fiber cable. ## Claims ### Claim 1 A fiber optic cable transition assembly, comprising: a fiber optic cable including a plurality of optical fibers; a plurality of furcation tubes; a housing extending from a first end of the housing to an opposite second end of the housing along an axis, the housing defining an internal passageway, the fiber optic cable entering the internal passageway through the first end, the plurality of furcation tubes entering the internal passageway through the second end, with the plurality of optical fibers extending within the passageway from an end of the fiber optic cable into the plurality of furcation tubes; a first plug fully surrounding the fiber optic cable and the axis and positioned in the internal passageway; and a second plug fully surrounding the plurality of furcation tubes and the axis and positioned in the internal passageway. ### Claim 2 (depends on 1) The fiber optic cable transition assembly of claim 1, further comprising: a first boot fully surrounding the fiber optic cable and the axis and extending through the first end into the internal passageway; and a second boot fully surrounding the plurality of furcation tubes and extending through the second end into the internal passageway. ### Claim 3 (depends on 2) The fiber optic cable transition assembly of claim 2, wherein a portion of the first plug is received inside the first boot; and wherein a portion of the second plug is received inside the second boot. ### Claim 4 (depends on 3) The fiber optic cable transition assembly of claim 3, wherein the portion of the first plug is configured to be coupled to the first boot by a snap connection; and wherein the portion of the second plug is configured to be coupled to the second boot by a snap connection. ### Claim 5 (depends on 4) The fiber optic cable transition assembly of claim 4, wherein the first plug is configured to prevent flow of epoxy into the first boot; and wherein the second plug is configured to prevent flow of epoxy into the second boot. ### Claim 6 (depends on 1) The fiber optic cable transition assembly of claim 1, wherein the housing defines an enclosed epoxy injection port. ### Claim 7 (depends on 6) The fiber optic cable transition assembly of claim 6, including a volume of hardened epoxy positioned in the internal passageway. ### Claim 8 (depends on 6) The fiber optic cable transition assembly of claim 6, wherein the housing defines an enclosed vent aperture. ### Claim 9 (depends on 8) The fiber optic cable transition assembly of claim 8, wherein the housing defines two enclosed epoxy injection ports. ### Claim 10 (depends on 1) The fiber optic cable transition assembly of claim 1, wherein the housing is cylindrical. ### Claim 11 (depends on 1) The fiber optic cable transition assembly of claim 1, wherein each of the first plug and the second plug includes a pair of sections. ### Claim 12 (depends on 11) The fiber optic cable transition assembly of claim 11, wherein each pair of sections are opposingly symmetrical. ### Claim 13 (depends on 11) The fiber optic cable transition assembly of claim 11, wherein each pair of sections are secured to each other around the fiber optic cable and around the furcation tubes, respectively, with mounting features. ### Claim 14 (depends on 13) The fiber optic cable transition assembly of claim 13, wherein the mounting features include opposing male inserts and female receivers. ### Claim 15 (depends on 1) The fiber optic cable transition assembly of claim 1, wherein an outer wall of the housing is thicker at the first end than at the second end. ### Claim 16 (depends on 1) The fiber optic cable transition assembly of claim 1, wherein the fiber optic cable and the plurality of furcation tubes include aramid yarn. ### Claim 17 (depends on 1) The fiber optic cable transition assembly of claim 1, wherein the internal passageway defines a narrow internal region that engages the first plug. ### Claim 18 (depends on 1) A method, comprising: assembling a conveyable assembly by: providing the cable transition assembly according to claim 1; and conveying the conveyable assembly thorough a cabling conduit by pulling, pushing and/or blowing the conveyable assembly though the cabling conduit.
