Abstract: Connector assemblies having an adjustable polarity are described. A connector assembly having an adjustable polarity comprises a housing and a locking component configured to couple to the housing, the locking component including a compression element. The connector assembly further comprises a latch component configured to rotate around the locking component when the compression element is compressed to change the polarity of the connector assembly from a first polarity when the latch component is located at a first polarity position to a second polarity when the latch component is located at a second polarity position.

Abstract: An optical connector holding one or more optical ferrule assembly is provided. The optical connector includes an outer body, an inner front body accommodating the one or more optical ferrule assembly, ferrule springs for urging the optical ferrules towards a mating receptacle, and a back body for supporting the ferrule springs. The outer body and the inner front body are configured such that four optical ferrule assembly are accommodated in a small form-factor pluggable (SFP) transceiver footprint or eight optical ferrule assembly are accommodated in a quad small form-factor pluggable (QSFP) transceiver footprint. A receptacle can hold one or more connector inner bodies forming a single boot for all the optical fibers of the inner bodies.

Abstract: A cleaning device is provided for removing debris from an end surface of a fiber optic connector. The fiber optic connectors may be a Multi Push On (MPO) or Mechanical Transfer (MT). The end surface may have a one or more ferrules with a fiber optic glass cable. The cleaning device includes a housing with a first end open to a gel that adheres to debris. A second end of the housing may be releasably attached to a protrusion or handle to insert and remove the device from an adapter receptacle. The handle may be replaced with a plug frame and protrusion so the device may be inserted into the receptacle of the adapter. The device may be placed over the end surface of the fiber optic connector that is not inserted into an adapter receptacle.

Abstract: A fiber optic connector includes a housing having an internal cavity and a front opening. A back post has an internal cavity, a front opening and a rear opening. The back post is operatively connected to the housing so that the internal cavity of the back post communicates with the internal cavity of the housing. At least two ferrules are disposed at least partially within the internal cavity of the housing and are exposed through the front opening of the housing. Each ferrule has a cylindrical shape and includes a flange. Each ferrule couples to an optical fiber. A fiber guide is coupled to each ferrule. Each fiber guide receives one of the optical fibers. Each fiber guide extends rearward from the ferrule. Each fiber guide extends in the internal cavity of the housing and the internal cavity of the back post. Each fiber guide is bent as the fiber guide extends rearward from the internal cavity of the housing to the internal cavity of the back post.

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 having an adjustable polarity are described. A connector assembly comprises a frame comprising a single housing having top and bottom frame components, first and second plug frames located within the housing, a first ferrule located in the first plug frame, a second ferrule located in the second plug frame, and a latch component attached to the top or bottom frame component, the latch component having at least one compression element. The latch component is configured to rotate around the housing when the at least one compression element is compressed to change the polarity of the connector assembly from a first polarity when the latch component is located at a first polarity position to a second polarity when the latch component is located at a second polarity position

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.
