Front housings of the connector portions can each be rotated about the longitudinal axis of the ferrule without rotating the ferrule or the boot, to change the polarity of the two connector portions. The spacing between the two ferrules is adjustable. A holder holds the connector portions, the holder including side slots, the connector portions mounted to the holder by moving laterally to the side slots. The holder defines an area for receipt of a fiber optic cable when the ferrule is pushed in a direction toward the boot. ## Claims ### Claim 1 A connector comprising: two connector portions each including a ferrule and a latch, each latch including a proximal end, wherein the proximal end of the latch is pivotable in an upward direction away from the connector portions; and a boot including slots for the proximal ends of each latch mounted to the connector portions, the boot movable longitudinally relative to the connector portions; wherein the boot causes unlatching of the latch as the boot is moved away from the connector portions. ### Claim 2 (depends on 1) The connector of claim 1, wherein a front housing of each of the connector portions can each be rotated about its longitudinal axis to change the polarity of the two connector portions. ### Claim 3 (depends on 1) The connector of claim 1, further comprising a holder for holding the connector portions, the holder including side slots, the connector portions being mounted to the holder by moving laterally to the side slots. ### Claim 4 (depends on 3) The connector of claim 3, wherein the holder defines an area for receipt of a fiber optic cable when the ferrule is pushed in a direction toward the boot. ### Claim 5 A connector comprising: a) two LC connector portions each including: i) a ferrule assembly including a ferrule and a hub mounted together, and a spring, an end of the ferrule protruding from each connector portion and the spring located in an interior area biasing the ferrule toward an extended position; and ii) a front housing mounted to the ferrule assembly to form a front of the connector portion, and including a latch, each latch including a distal end and a proximal end, wherein the latch is pivotable about an intermediate connection portion, wherein the distal end includes a shoulder for mating with a latching shoulder of an adapter; b) a holder for holding the connector portions, the holder including a rearwardly projecting crimp support; and c) a boot mounted to the holder, the boot movable longitudinally relative to the holder and the connector portions, wherein the boot engages the proximal ends of the latches and causes the distal ends of the latch to pivot toward the ferrule of each connector portion as the boot is moved away from the connector portions, wherein the boot includes slots on both sides of the boot for receiving the proximal ends of the latches, as the connector portions are rotated to change polarity without rotating the boot. ### Claim 6 (depends on 5) The connector of claim 5, wherein the connector portions can each be rotated about its longitudinal axis to change the polarity of the two connector portions. ### Claim 7 (depends on 5) The connector of claim 5, wherein the holder defines an area for receipt of a fiber optic cable when the ferrule is pushed in a direction toward the boot. ### Claim 8 (depends on 5) The connector of claim 5, further comprising a boot return mechanism including a return spring for biasing the boot toward the connector portions. ### Claim 9 (depends on 5) The connector of claim 5, wherein the front housing including the latch is a one-piece housing. ### Claim 10 A connector comprising: a) two connector portions each including: i) a ferrule assembly including a ferrule and a hub mounted together, and a spring, an end of the ferrule protruding from each connector portion and the spring located in an interior area biasing the ferrule toward an extended position; and ii) a front housing mounted to the ferrule assembly to form a front of the connector portion, and including a latch, each latch including a distal end and a proximal end, wherein the latch is pivotable about an intermediate connection portion, wherein the distal end includes a shoulder for mating with a latching shoulder of an adapter; b) a holder for holding the connector portions, the holder including side slots, the connector portions mounted to the holder by moving laterally to the side slots, the holder including a rearwardly projecting crimp support; and c) a boot mounted to the holder, the boot movable longitudinally relative to the holder and the connector portions, wherein the boot engages the proximal ends of the latches and causes the distal ends of the latches to pivot toward the ferrule of each connector portion as the boot is moved away from the connector portion, wherein the boot includes slots on both sides of the boot for receiving the proximal ends of the latches, as the connector portions are rotated to change polarity without rotating the boot, and wherein the boot includes ramps for unlatching the latches when the boot is pulled axially away from the connector portions.
