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, a key disposed along a side of the inner housing, wherein the inner housing includes at least one protrusion configured to lock the key, and an outer housing disposed around at least a portion of the inner housing and the key. The outer housing may be configured to be pulled rearward relative to the inner housing, and further configured to unlock the key to allow slideably moving the key from a first position to a second position.

Abstract: A fiber optic cable guide may have an elongated base member that is curved along at least a portion of its length to define and limit the amount of curvature to be applied to a portion of a fiber optic cable while also defining the angular offset applied to the cable. The guide may be releasably attachable to a cable, and may include a cable retention member at each end of the base member that retains the cable with the guide.

Abstract: Connector assemblies having an adjustable polarity are described. For example, at least two ferrules may be arranged in a housing of the connector assembly within independent frame plugs in a certain polarity. A top portion of the housing may be removed to allow access to the frame plugs. Accordingly, an installer may open the housing, switch the polarity of the ferrules, and then re-couple the top portion to the housing. In another example, the connector assembly may include a latch that may rotate about the connector assembly from a first polarity position to a second polarity position. The connector assembly may include a compression element that may facilitate the rotation of the latch when the compression element is compressed. In this manner, the latch may be rotated to a different polarity position to allow the connector assembly to be connected to an adapter using a different polarity.

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 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: 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: A stackable adapter having opposing ports configured to accept differing fiber optic connectors along a longitudinal axis. The stackable adapter is formed from opposing partially open sidewalls having a recess and a protrusion opposite one another near a top edge and bottom edge. Mating two stackable adapters forms a stackable adapter assembly with stackable outer sidewalls for reducing the width of an array of two stackable adapters by at least one-third over placing two standard adapter side-by-side in the panel.
