A new fiber optic connector provides a smaller form factor by including two ferrule assemblies in a housing. The housing accepts a push-pull mechanism that allows for insertion and removal from a carrier as well as an adapter. The push-pull mechanism may also include a flexure member to return the push-pull mechanism. Polarity of the fiber optic connector may also be selected by use of the push-pull mechanism.

An optical connector holding two or more LC-type optical ferrules is provided. The optical connector includes an outer housing, ferrules, a cable boot and one or more polarity keys. The keys are configured to change connector polarity from a first to a second polarity. A corresponding adapter with one or more slots within an adapter wall on opposing sides sized and shaped to accept a single or dual keyed polarity changeable connector.

An optical fiber connector configured to rotationally align a first optical fiber with a second optical fiber is provided. The connector can include at least two rotational alignment features. At least one of the two rotational alignment features can include at least one ferrule configured to hold at least the first optical fiber.

An optical fiber terminal structure is comprised of a plurality of optical fibers, a plurality of high- optical fibers connected to the optical fibers, respectively, and a capillary. The capillary has a hole in which the optical fibers and the high- optical fibers are inserted, and the optical fibers and the high- optical fibers together are fixed in the hole. Connection parts of each of the optical fibers and the high- optical fibers are also positioned inside the capillary, and end surfaces of the high- optical fibers are exposed so that adjacent high- optical fibers are in contact with each other in an end surface of the capillary.

At least one of the two rotational alignment features can include at least one ferrule configured to hold at least the first optical fiber.

Disclosed is a polarization maintaining connector. The PM connector includes an outer frame, a ferrule structure and an adjustment member. The outer frame forms a main structure of the PM connector. The ferrule structure is provided with a channel for a fiber core to pass through. The ferrule structure is at least partially disposed inside the outer frame and forms a slidable and rotatable connection with the outer frame. The adjustment member forms an axially slidable connection with the ferrule structure and is circumferentially non-rotatable relative to the ferrule structure. The adjustment member is relatively rotatable to the outer frame and has a rotating state and a holding state. The adjustment member keeps relatively rotatable to the outer frame when in the rotating state and keeps relatively secured to the outer frame when in the holding state.

A polarization maintaining fiber array includes a substrate, a cover, and at least two polarization maintaining optical fibers. The substrate includes at least two main grooves, a first additional groove, and a second additional groove, wherein the main grooves are positioned between the first additional groove and the second additional groove. The fiber array includes at least two polarization maintaining optical fibers positioned in the at least two main grooves, a first dummy fiber positioned in the first additional groove, and a second dummy fiber positioned in the second additional groove. The cover is positioned such that it contacts the polarization maintaining optical fibers, the first dummy fiber, and the second dummy fiber.
