A fiber optic connector assembly includes a hybrid adapter assembly and fiber optic connectors. The hybrid adapter assembly includes a first adapter and a second adapter connected to each other. The first adapter is connected to a first fiber optic connector, and the second adapter is connected to a second fiber optic connector in abut joint with the first fiber optic connector. The second adapter is provided with a connection arm configured to fasten the second fiber optic connector and is further provided with a transition bridge configured to assist the abut joint between the first fiber optic connector and the second fiber optic connector. The structure of the fiber optic connector assembly is simplified. After a matching mechanism of the second adapter and the second fiber optic connector is optimized, connection and disconnection can be implemented by plugging and unplugging.

A fiber optic cable assembly or termination system is preconnectorized and may include different combinations of collars, crimp bands, and clamp assemblies to improve functionality of the arrangement.

When a second housing 80 and a first housing 30 are approached to each other along an axial direction, a body portion 62 of a second fixing member 60 begins to enter in an opening 81 of the second housing 80. Since a vertical wall surface 81a and a cylindrical surface 81b are formed on the opening 81 to substantially match the outer shape of the rear end of the body portion 62, when the second housing 80 is inserted to the first housing 30 while keeping the relative angle until the second housing 80 abuts on a first fixing member 40 which closes the opening and rotating the second housing 80 with respect to the first housing 30 by 90, a protrusion 64 faces and enters a recessed engagement portion 83 formed on the vertical wall surface 81a. Thus, the protrusion 64 and the recessed engagement portion 83 are fitted and fixed.

A fiber deployment system is suitable for field installed fiber tubes such as blown fiber tubes. The fiber deployment system includes a fiber optic connector including a housing assembly having a connector body and a fiber tube attached at a rear end of the connector body. A ferrule assembly mounted on a deployable fiber can be loaded into the connector body through the fiber tube. The fiber tube can be coupled to a field installed fiber tube by a tube coupler.

An optical fiber connection system includes a first and a second optical fiber, each with end portions that are terminated by a first and a second fiber optic connector, respectively. A fiber optic adapter connects the first and the second fiber optic connectors. A fiber alignment apparatus includes V-blocks and gel blocks. Each of the fiber optic connectors includes a connector housing and a sheath. The end portions of the optical fibers are positioned beyond distal ends of the respective connector housings. The sheath is slidably connected to the connector housing and slides between an extended configuration and a retracted configuration. The sheath covers the end portion of the respective optical fiber when the sheath is at the extended configuration and exposes the end portion when at the retracted configuration. The end portions of the optical fibers are cleaned when slid between the V-blocks and the gel blocks.

An optical connector includes a ferrule, a first optical fiber retained in the ferrule, a clamp section including an insertion section where a second optical fiber is inserted, a solid index-matching material disposed on an end face of the first optical fiber on an insertion section side, and a projecting portion on the end face of the first optical fiber and that projects more toward the insertion section side than a central region of the end face. The clamp section centers and fixes the first optical fiber and the second optical fiber.

An adapter is configured to connect to a connector. The adapter includes a first housing and an electrical connector. The first housing is defined a first accommodating groove and a through hole communicating with each other. The electrical connector includes an electrical connecting portion, a supporting portion, and an elastic portion. The supporting portion connects the electrical connecting portion to the elastic portion. The supporting portion is accommodated in the through hole, and the electrical connecting portion extends through the first housing; the elastic portion extends from the supporting portion toward the first accommodating groove; the elastic portion is configured to be bent relative to the supporting portion, and the elastic portion is configured to electrically connect to a terminal. The present disclosure provides a connector and an opto-electric transmission assembly.

A ferrule can be assembled in the field. A ferrule collar has a non-circular, in particular polygonal outer contour. A corresponding coding region of a ferrule housing is arranged in a portion of a contact chamber on a cable-connection side and has a non-circular, in particular polygonal cross section, in which the ferrule collar is held with a form fit over the entire spring displacement path. The ferrule spring acts on the ferrule collar over the entire displacement path. As a result, the ferrule is secured against rotation about its axis by a high holding force, which makes it easier for a fibre-optic cable to be screwed on. The structural form is particularly well-suited for use in a plug-in connector module.

A pre-connector is configured to detachably fix to an optical fiber group. The pre-connector includes a shell assembly and a limiting member. The shell assembly is configured to accommodate one end of the optical fiber group. The limiting member is clamped in the shell assembly and is configured to press against the optical fiber group to fix the optical fiber group to the shell assembly. The present disclosure further provides a connector including the pre-connector.

A fiber optic cable assembly or termination system is preconnectorized and may include different combinations of collars, crimp bands, and clamp assemblies to improve functionality of the arrangement.
