Guide beams on the pin exchanger provide a reference for aligning the guide pins and the pin exchanger with a fiber optic connector and a fiber optic ferrule. An adapter is also provided that has openings to receive the guide beams. The adapter is preferably installed in a field tool and together they engage the fiber optic connector, align the pin exchanger and move the guide pin holder to allow guide pins to be inserted or removed. ## Claims ### Claim 1 A combination of a field tool and a pin exchanger to change a gender of a fiber optic connector, comprising: a field tool further comprising: a main body with an opening to receive an adapter, two handles movable towards each other, and a pair of plungers in relatively offset positions within the main body and each having a pin configured to engage a pin keeper in the fiber optic connector when the two handles are moved towards each other via corresponding offset openings in the fiber optic connector; and a pin exchanger engageable with the field tool at the adapter, the pin exchanger further comprising: a pair of gripping elements having a space between each gripping element of the pair of gripping elements, a pair of guide pins being receivable in the space, and a guide beam attached to each gripping element of the pair of gripping elements, wherein the adapter of the field tool includes two guide beam openings to respectively receive the guide beam attached to the each gripping element during a gender change operation of the fiber optic connector. ### Claim 2 (depends on 1) The combination according to claim 1, wherein during the gender change operation, the pair of guide pins are partly positioned inside the opening. ### Claim 3 (depends on 1) The combination according to claim 1, wherein the two handles are joined to the main body but separated from each other. ### Claim 4 (depends on 1) The combination according to claim 1, wherein during the gender change, the guide beam engages a housing of the fiber optic connector. ### Claim 5 (depends on 1) The combination according to claim 1, wherein the guide beam is positioned between two latches of the adapter. ### Claim 6 (depends on 1) The combination according to claim 1, wherein each guide pin in the pair of guide pins has an end with a groove, the end with the groove positioned freely outside the pair of gripping elements. ### Claim 7 (depends on 1) The combination according to claim 1, wherein the guide beam protrudes beyond the two guide beam openings of the adapter when the pin exchanger is engaged with the adapter. ### Claim 8 (depends on 1) The combination according to claim 1, wherein the adapter comprises two secondary latches to engage with the field tool when the adapter is positioned inside the opening. ### Claim 9 (depends on 1) The combination according to claim 1, wherein the pin exchanger further comprises a pair of protrusions extending towards each other into the space respectively from the pair of gripping elements, wherein the pair of guide pins are engaged to the pair of protrusions. ### Claim 10 A combination of a field tool, a pin exchanger and an adapter to change a gender of a fiber optic connector comprising: a field tool having a main body with two handles positioned on opposite sides of the main body, the two handles angularly movable towards each other about respective pivot points on the main body; an adapter positioned inside an opening of the main body; and a pin exchanger engageable with the field tool at the adapter and having a pair of gripping elements with a space therebetween to receive a pair of guide pins for insertion into or for removal from the fiber optic connector, the pin exchanger also having a first guide beam and a second guide beam on opposite sides thereof, wherein the adapter is configured to engage both the pair of guide beams and the fiber optic connector during a gender change operation when at least a portion of the fiber optic connector is received inside the adapter, and wherein the field tool further comprises a pair of plungers with pins in relatively offset positions within the main body to engage a pin keeper of the fiber optic connector received at least partially inside the adapter. ### Claim 11 (depends on 10) The combination according to claim 10, wherein the pins of the pair of plungers are positioned partially inside the fiber optic connector via fiber optic connector openings when the pair of plungers are angularly rotated towards each other to engage the pin keeper. ### Claim 12 (depends on 11) The combination according to claim 11, wherein the adapter includes a pair of connector springs to engage an outer housing of the fiber optic connector thereby exposing the fiber optic connector openings on an inner housing of the fiber optic connector. ### Claim 13 (depends on 10) The combination according to claim 10, wherein the adapter includes a central opening to receive the fiber optic connector and two side openings to respectively receive the first guide beam and the second guide beam of the pin exchanger. ### Claim 14 (depends on 10) The combination according to claim 10, wherein when the pin exchanger and the fiber optic connector are positioned inside the adapter, the pair of guide pins are aligned with a pair of guide pin openings in the fiber optic connector. ### Claim 15 (depends on 10) The combination according to claim 10, further comprising a gripper engageable with the pin exchanger, the gripper having handles to apply a force to the pin exchanger. ### Claim 16 (depends on 10) The combination according to claim 10, wherein the pin exchanger further comprises a pair of protrusions extending towards each other into the space respectively from the pair of gripping elements, wherein the pair of guide pins are engaged to the pair of protrusions during both an insertion and a removal of the pair of guide pins for the gender change operation. ### Claim 17 (depends on 10) The combination according to claim 10, wherein the pin exchanger engages the fiber optic connector. ### Claim 18 (depends on 17) The combination according to claim 17, wherein the pin exchanger engages an inner housing of the fiber optic connector. ### Claim 19 (depends on 10) The combination according to claim 10, wherein the fiber optic connector is an MPO-type connector. ### Claim 20 (depends on 10) The combination according to claim 10, wherein the pair of guide pins are positioned between the first guide beam and the second guide beam.
