Abstract: A fiber optic ferrule sub-assembly for insertion into an outer housing of a fiber optic connector includes a ferrule assembly having a ferrule that forms an optical communication connection with another fiber optic device. A back housing includes a back post to be attached to a fiber optic cable. A spring is operatively disposed between the ferrule assembly and the back housing. A linkage connects the ferrule assembly to the back housing such that the spring is compressed and biases the ferrule away from the back housing prior to insertion of the fiber optic ferrule sub-assembly into the outer housing.

Abstract: An optical connector holding two or more LC-type optical ferrules is provided. A plural of optical connectors are ganged together into when insert into an adapter. To remove the connectors together or individually a removal tool is attachable to one or more of the connectors. The removal tool has a plural of release arms that in first position can release the fiber optic connector from the adapter receptacle. Release aim in a second position prevents the fiber optic connector from being released from the adapter receptacle. The removal tool is moved distally to actuate or retain the fiber optic connectors within their corresponding adapter receptacle.

Abstract: Optical fiber connectors configured to allow ease of change of the connector polarity by providing lockable outer housing. In an embodiment, an optical fiber connector comprises an inner housing, at least one key configured to move along the inner housing so as to change a polarity of said optical fiber connector, and an outer housing disposed around at least a portion of the inner housing and configured to slide in a longitudinal direction so as to expose at least a portion of said at least one key, wherein the outer housing includes a flexible portion configured to lock to the inner housing so as to retain the outer housing in a pulled back position relative to the inner housing. A removable alignment key is reattached to the connector to correspond to a first or second polarity.

Abstract: Low profile optical fiber connectors comprising a ferrule, a plug frame configured to receive the ferrule, and an outer housing configured to receive the plug frame. The outer housing may be configured to protrude less than about 2 mm from one end of an adapter when the low profile optical fiber connector is inserted into the adapter. The connector may include a boot sized such that the boot protrudes from the end of the adapter by less than about 15 mm. The low profile connector does not contain a bias spring to urge the ferrule forward out of plug frame housing.

Abstract: An optical fiber connector includes an optical fiber ferrule and a single-piece housing in which the ferrule is received. The housing can be installed in an adapter to make an optical connection. A rotational locking mechanism has a rotor mounted on the housing for rotation with respect the housing about a rotational axis. The rotor can be rotated between a locked position and an unlocked position. The rotational locking mechanism is configured to inhibit the housing from being withdrawn from the adapter in the locked position of the rotor and to permit the housing to be withdrawn from the adapter in the unlocked position, and further comprising a guide pin, wherein the housing comprises an integral guide pin retainer configured to hold the guide pin in place on the housing.

Abstract: Connector assemblies are described herein. For example, a connector assembly including: a housing configured to accept a first ferrule and a second ferrule. The connector assembly may also have a latch component that is removably connected to the housing, wherein the latch component is configured to rotate around the housing. The latch component may have a first locking element configured to engage a second locking element to prevent rotation of the latch component in at least one of a first polarity position to a second polarity position. The connector may further more include a push-pull tab removably connected to the housing and configured to move vertically along the housing when a biasing force is applied in at least one of a forward direction and a rearward direction. Accordingly, the push-pull tab can compress the latch component when moving vertically along the housing.
