Abstract: A new fiber optic connector provides a very small form factor with reduced size. The fiber optic connector may comprise a single-body housing having a front end and rear end in a longitudinal direction, two ferrules accommodated in the housing and protruding from the front end of the housing, a back housing positioned adjacent to the rear end of the housing, two springs positioned between the two ferrules and the back housing to urge the two ferrules to move forward, and a boot assembly connected to the rear end of the housing. The housing comprises a latch arm extending obliquely upwards, and the latch arm is in a depressed state when the fiber optic connector is mating with an adapter.

Abstract: A multi-fiber, fiber optic connector is interchangeable between a male connector and a female connector by including a pin retainer having a releasable retention device configured to lock the pins in place within the retainer. The retention device may be opened, for example, with a release tool, to free the retention pins for removal of the pins. A method for switching a connector between a male connector configuration and a female connector configuration may be possible as a result of the releasable retention configuration.

Abstract: An MPO connector has an elongated outer housing and a push-pull boot. The front end portion of the push-pull received in the interior of the extended rear portion of the outer housing. The front end portion of the push-pull boot is linked to the opposing side portions of the outer housing such that the outer housing moves backward in relation to the main body when the push-pull boot is pulled backward. The front end portion of the push-pull boot can comprise opposing side walls with opposing side tabs projecting outward for operably connecting the push-pull boot to the elongated outer housing of the MPO connector.

Abstract: Systems and methods of using a multiport assembly and associated components are disclosed. The multiport assembly can include a multiport device that communicatively couples multiple sets or pairs of connectors, such as optical connectors or electrical connectors, together. The multiport assembly can also include an auxiliary port device that couples to the multiport device to expand the capacity of the multiport assembly. Both the multiport and auxiliary port devices can be selectively configured to receive specific types of connectors by selectively coupling to different types of adapters, where the types of adapters correspond to the types of connectors. When coupled to the multiport or auxiliary port devices, the adapters facilitate the formation of the communication between its corresponding set of connectors.

Abstract: A fiber optical connector assembly with a crimp tube assembly improves tensile load on the optical fiber cable or microduct jacket when the connector assembly is used as part of an optical network that is secured between towers spaced apart 1,000 meters or more. The crimp tube assembly has one or more crimp zones, and the crimp tube assembly has a lip formed on an inner surface of the crimp right assembly to improve tensile strength when the crimp tube assembly is secured to a back post of a first fiber optic connector assembly that is air blown or push through a duct or conduit. An epoxy resin may be injected into a cavity between the cable jacket and the crimp tube assembly to improve tensile load strength.

Abstract: The fiber optic adapter according to the present disclosure may include an adapter housing defining a channel to receive a fiber optic connector having one or more ferrules, and a first shutter and a second shutter attached to opposing sidewalls of the adapter housing. Each of the first and second shutters have a first member and a second member. The first member is configured to extend into the channel. the first members of the first and second shutters are sized and shaped to cooperatively close the channel. At least one of the first member is resiliently movable upon insertion of the fiber optic connector into the channel to open the channel. The fiber optic adapter may prevent the entry of the dust and other debris.

Abstract: In a connector for terminating a cable, a connector housing has a rear end portion including a first shoulder. An inner connector assembly is received in the connector housing. The inner connector assembly includes at least one ferrule exposed and a back body with a back post. At least one strength member is secured to the back post. A rear bracing member is received in the connector housing. The rear bracing member has a front end portion and a rear end portion spaced apart along the longitudinal axis. The front end portion of the rear bracing member is configured to engage the back body and the rear end portion of the rear bracing member is configured to engage the first shoulder of the connector housing such that the rear bracing member substantially braces the back body against rearward displacement along the longitudinal axis relative to the connector housing.
