A ferrule includes a ferrule body having a first opening formed in a side face thereof, and having a second opening formed in a top face thereof, wherein the first opening is configured to receive an optical waveguide inserted into the ferrule body at the side face, and wherein the second opening is formed over and in communication with the first opening, such that the second opening connects an inner space of the first opening to an outside of the ferrule body.

Fiber connecting devices (100) are described that include a mechanical element (160) that may be opened and closed a plurality of times using an actuation mechanism (150, 150), where the mechanism (150, 150) allows for securing of the glass portions (56, 56) of two optical fibers (50, 50) at the same or different times, and allows for connection of the optical fibers (50, 50). Methods of connecting two optical fibers (50, 50) using such a device (100) are also described.

An optical connector includes first and second ferrules, first and second front housings each accommodating a corresponding ferrule of the first and second ferrules inside, an inner housing connected to rear ends of the first and second front housings, an outer housing including a first latch and accommodating the inner housing inside, and a tab disposed in a second direction intersecting a first direction with respect to the outer housing. The inner housing includes second latches disposed on first and second side portions respectively. The first and second side portions arranged in a third direction intersecting both the first direction and the second direction. The second latches include respective engaging portions that are engageable with the outer housing. Each of the engaging portions is pushed toward the inside of the inner housing to release a state of engagement between the inner housing and the outer housing.

A front housing of the optical-electrical composite connector is axially provided with a through groove passing through the front housing on the front housing, and an inner wall of the through groove is provided with a first groove. A rear housing includes a main body portion and a clamping portion connected to one end of the main body portion. An outer surface of the clamping portion is axially provided with a second groove, the clamping portion is located in the through groove, and the first groove is butted with the second groove to form an accommodation space. One end that is of the through groove and that is away from the main body portion is an optical port. The font housing is provided with an opening connecting to the accommodation space and the outside. The conductive terminal is accommodated in the opening, and the conductive terminal forms an electrical port.

A ferrule assembly and a fiber optic fast connector comprising the same are provided. The ferrule assembly comprises a tailstock provided with a window portion, in which a supporting platform is provided, and having an end provided with an opening. A ferrule is provided, with a receiving cavity for receiving an optical fiber. The ferrule has one end passing through the opening and then abutting against and connecting with the supporting platform to constitute a stepped portion and provided with a groove portion, and has another end located outside of the tailstock. A pressing block is provided, comprising abutting against and connecting with the groove portion, an end handle portion abutting against and connecting with the stepped portion, and a flexible portion connected with the pressing portion and the end handle portion, respectively. A lock catch slidably sleeved on the tailstock is provided.

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.

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 optical plug connector device includes at least one lens array and at least one fiber holder, which is designed to position end regions of a plurality of optical fibers relative to the lens array, and which has at least one first fiber holding element wherein the fiber holder comprises at least one second fiber holding element having a higher manufacturing precision than the first fiber holding element.

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.
