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 The rotational locking mechanism is configured to inhibit the housing from being withdrawn from the adapter in the locked position of the rotor and to permit the housing to be withdrawn from the adapter in the unlocked position, and further comprising a guide pin, wherein the housing comprises an integral guide pin retainer configured to hold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: Fiber optic connection assemblies that may include hybrid adapters and connector assemblies are generally described. The hybrid adapter may be configured to connect a first connector type and a second connector type, the first connector type being different from the second connector type. For example, the first connector type may be a micro connector and the second connector type may be an LC connector. A connector assembly may be configured as a micro connector having a tension element configured to facilitate optimized optical performance by spring loading the ferrules while maintaining a small form factor.

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 managed fiber optic connector assembly formed with an optical fiber management enclosure. The optical fiber management enclosure is formed with a back body as one-piece to form an integrated fiber optic management enclosure, or fiber optic management enclosure is inserted into the back body form a two-piece enclosure. The fiber management enclosure has a plural of channels, for example, an upper channel and a lower channel that retain, separate and guide a plural of optical fibers that are accepted through a port at a distal end of the managed fiber optic connector assembly.

Abstract: A behind-the-wall optical connector having an outer housing configured to be inserted into an adapter with a corresponding inner surface, and a latch attached to one side of housing configured to lock the connecter into an adapter opening. The latch is further configured with a locking channel and guide to accept a pull tab with a catch at one end, the pull tab releases the connector from the adapter opening when the tab is pulled rearward or away from the adapter. The ferrule assembly is inserted into a first end of the housing and when latched to the adapter, the assembly is retained in the housing without any locking structure therein.
