A ferrule positioned at the front end. The ferrule has a distal end face with a central region and recessed regions on opposite sides of the central region. The assembly includes a dust cap mounted on the ferrule. The dust cap has an open end and an opposite closed end. The fiber optic connector assembly also includes a tape member that covers the central region of the ferrule. The tape member can be secured to the dust cap such that when the dust cap is removed, the tape member simultaneously comes off with the dust cap. ## Claims ### Claim 1 An apparatus for applying protective sheeting on an end face of a ferrule connector, the apparatus comprising: a housing; a microscope for inspecting the end face of the ferrule connector, a portion of the microscope being positioned within the a housing of the apparatus, the housing defining an adapter port for receiving the ferrule connector, wherein when the ferrule connector is mounted into the adapter port, the end face of the ferrule connector projects within the housing for inspection by the microscope, the housing limiting access of loose particles of dust and debris therein; and an integrated tape application station including a mechanism for dispensing tape within the housing of the apparatus, the integrated tape application station applying a tape member to the end face of the ferrule connector while the ferrule connector is positioned within the adapter port of the housing. ### Claim 2 (depends on 1) The apparatus of claim 1, further comprising a feed roller to supply the tape member on a liner. ### Claim 3 (depends on 2) The apparatus of claim 2, further comprising a rewind roller that receives the liner from the feed roller after the tape member is removed. ### Claim 4 (depends on 1) The apparatus of claim 1, wherein the end face of the ferrule connector opposes the microscope to be inspected within the housing prior to application of the tape member. ### Claim 5 (depends on 3) The apparatus of claim 3, further comprising a roller that presses the tape member against the end face of the ferrule connector while the liner advances through the apparatus to be wrapped on the rewind roller. ### Claim 6 (depends on 1) The apparatus of claim 1, further comprising a blower for circulating air through the housing for removing contaminants from air. ### Claim 7 A method of applying a tape member to an end face of a ferrule connector using an apparatus, the apparatus including a housing that includes a microscope positioned therein, the housing defining an adapter port for receiving the ferrule connector, wherein when the ferrule connector is mounted into the adapter port, the end face of the ferrule connector projects within the housing, the housing also having an integrated tape dispensing mechanism therein, the method comprising: inspecting the end face of the ferrule connector using the microscope when the ferrule connector is inserted within the adapter port of the housing; and applying the tape member over the end face of the ferrule connector while the ferrule connector is positioned within the adapter port of the housing. ### Claim 8 (depends on 7) The method of claim 7, wherein the tape member contains a coloring agent. ### Claim 9 (depends on 7) The method of claim 7, wherein the tape member is transparent. ### Claim 10 (depends on 7) The method of claim 7, wherein the end face of the ferrule connector includes a central region and recessed regions on opposite sides of the central region, wherein the tape member is applied only to the central region of the end face of the ferrule connector. ### Claim 11 (depends on 7) The method of claim 7, further comprising the step of blowing air through the housing of the apparatus to limit dust particles therein. ### Claim 12 (depends on 7) The method of claim 7, further comprising the step of moving a press roller that is within the housing of the apparatus across the end face of the ferrule connector to press the tape member onto the end face of the ferrule connector. ### Claim 13 (depends on 12) The method of claim 12, wherein the press roller is spring loaded. ### Claim 14 (depends on 7) The method of claim 7, wherein the tape member is a pre-cut piece carried to the end face of the ferrule connector within the housing of the apparatus on a backing strip. ### Claim 15 (depends on 14) The method of claim 14, wherein the backing strip is routed around a tight radius structure to disengage the tape member from the backing strip.
