An apparatus includes first and second components. A track supports one of the components for movement toward the other of the components. A first connector is mounted on the first component. The first connector retains an end portion of a first fiber optic cable, and has a first alignment portion. A second connector retains an end portion of a second fiber optic cable, and has a second alignment portion. The second alignment portion guides the second fiber optic cable radially into coaxial alignment with the first fiber optic cable upon movement of the first alignment portion against the second alignment portion. A floating mount device supports the second connector on the second component for guided movement radially relative to the second component upon movement of the first alignment portion against the second alignment portion.

An optical connecting part includes: a holder including an end face for optical connection, one or more optical waveguides and a through-hole, the optical waveguides having a portion extending from the end face in a direction of a first axis, the through-hole extending from the end face in the direction of the first axis; and a coating disposed on an inner surface of the through-hole, the coating having oil repellency. The coating on the inner surface of the through-hole forms a guide hole.

A ferrule for an optical connector includes a body, a cavity extending into the body from a back end of the body, and first and second groups of micro-holes extending into the cavity from a front end of the body. The cavity includes at least one bottom surface extending under an opening in a top surface of the body and below a first plane that extends through or below the first and second groups of micro-holes. The cavity also includes a divider extending under the opening in the top surface of the body, with the divider having a divider surface positioned above the first plane such that the divider surface is offset from the at least one bottom surface.

Multi-fiber ferrules may be produced with tapered bodies and guide pin holes that have fluted internal surfaces with projections for engaging the guide pins, and channels for capturing any foreign material that may accumulate on or around the guide pins, thereby providing improved consistency in fiber connections during mating of the ferrules.

A multi-fiber, fiber optic connector is provided having a housing having a first end for receiving a multi-fiber fiber optic cable and a second end having openings for the fibers from the cable. First and second keys for setting the polarity of the fibers within the connector located on opposing sides of the connector. The connector has either one of guide pins or guide pin receiving holes for guiding the connection with a second connector. The keys are movable between a first active position and a second retracted position, such that when one of the keys is in the first active position, the fibers are presented within the connector in a first polarity and when the second key is in the first active position, the fibers are presented within the connector in a second polarity reversed from the first polarity.

[Problem] To provide an optical connector that has small number of components and a simple configuration, and can reduce production costs, improve productivity, and reduce the size thereof.

[Solution] In this optical connector (10), a first connector (110) has: a first connector housing (120) formed in a tubular body shape and having an accommodation section therein; a spacer (400) which is in sliding contact with an inner surface of the accommodation section of the first connector housing and in which a first ferrule (130) is slidably provided; a biasing member (300) which biases the spacer toward a second connector (210) side; and a stopper (500) fixed to a rear section of the first connector housing on the side opposite from the second connector, wherein a recessed groove through which a first optical cable A passes is formed in the spacer and the stopper, and the biasing member has, between the spacer and the stopper, a pair of coil springs provided on both sides of the first optical cable A.

A housing for a fiber optic connector includes an opening extending between a front end and a rear end, and having an integral spring stop surface between the front end and the rear end. A front section receives an elastic member into the opening from the front end and the elastic member is engageable with the integral spring stop of the housing. There is a middle section of the main body to transition optical fibers between a fiber optic ferrule and a fiber optic cable. A rear section of the main body has an outer surface to engage a crimp ring.

An optical fiber connector according to the present disclosure includes a fiber ferrule, a spring, a coil spring seat and a spring push. An opening extends through the front end of the spring. The spring seat includes two first tooth portions and two second tooth portions. The spring seat has opposing front and rear surfaces. The front surface of the spring comes in contact with the fiber ferrule. An opening extends through the rear surface of the spring. The first tooth portions extend from the rear surface and the respective first tooth portion has a first inner surface and a first outer surface. The first outer surface is a curved surface. The second tooth portions extend from the rear surface and the respective second tooth portion has a second inner surface and a second outer surface. The second outer surface is a curved surface. The first and second tooth portions extend into the opening of the spring and the convex surfaces thereof come in contact with the inner sides of the spring. The spring push comes in contact with the rear end of the spring to push the spring toward the spring seat.

Embodiments herein describe attaching (or bonding) alignment parts to a photonic die so that these alignment parts can then be used to passively align a FAU to the photonic die. In one embodiment, the alignment part (or parts) is aligned to a photonic die using a mounting FAU. The mounting FAU (along with the mated alignment parts) can then be actively aligned to the photonic die. When aligned, the alignment parts can be bonded (e.g., using cured epoxy) to the photonic die. The mounting FAU can then be lifted off, leaving the alignment parts attached to the photonic die. Later, a final product FAU (which may have a different shape than the mounting FAU) can then be passively aligned to the photonic die using the previously mounted alignment part or parts.

A fiber-optic connector includes a connector body including a housing with a top surface and a bottom surface, the top surface and the bottom surface being joined together by two opposing side surfaces of the housing. The housing has a top slot and a bottom slot thereupon along a longitudinal axis, the top slot and the bottom slot being provided on the top surface and the bottom surface, respectively. A first key structure is slidably positioned within the top slot, and a second key structure is slidably positioned within a bottom.
