Abstract: A device for aligning a first and a second optical fibers each comprising an end mounted into a ferrule (1, 2), comprising:
- an alignment tube (5) in which the two ferrules are mounted in an interference fit, the two ferrules being opposite and spaced with each other;
- an optical component (7, 7', 7") that provides for both a non-physical contact and a low optical coupling loss between the first and second fibers, said component being positioned by a spacer (6) substantially at the midpoint between the first fiber (3) and the second fiber (4), such that the image of the end face of the first fiber (3) is coincident with the end face of the second fiber (4).

Abstract: A fiber optic cable and connector assembly is disclosed. In one aspect, the assembly includes a cable optical fiber, an optical fiber stub and a beam expanding fiber segment optically coupled between the cable optical fiber and the optical fiber stub. The optical fiber stub has a constant mode field diameter along its length and has a larger mode field diameter than the cable optical fiber. In another aspect, a fiber optic cable and connector assembly includes a fiber optic connector mounted at the end of a fiber optic cable. The fiber optic connector includes a ferrule assembly including an expanded beam fiber segment supported within the ferrule. The expanded beam fiber segment can be constructed such that the expanded beam fiber segment is polished first and then cleaved to an exact pitch length. The expanded beam fiber segment can be fusion spliced to a single mode optical fiber at a splice location behind the ferrule.

Abstract: A lens 311 of a plug 31 converts a light signal from an optical fiber cable 20 to light of a predetermined divergence angle in order to emit the light. A plug housing 315 fixes the optical fiber cable 20 and the lens 311. The lens 311 is positioned such that the light signal from the optical fiber cable 20 becomes the light of the predetermined divergence angle at an emission surface 20a side of the optical fiber cable 20. The light signal emitted from the plug 31 becomes dispersed when entering into the eyeball of a nearby person, and therefore can be prevented from exerting adverse effect on visual function and the like.

Abstract: Embodiments include a high bandwidth optical connection system suitable for interconnecting servers, for example within a rack of a datacenter. An edge mount optical connector assembly includes an edge-mount housing providing topside socket contacts proximate to a first end of the housing and a port at a second end to receive an optical plug connector. A socket latch cantilevered from an anchor point on the housing includes a latching face to contact a keeper face disposed on the housing and a spring load application surface between the anchor point and the latching face to apply a spring force against the electrical contacts for retention of a removable optical transceiver module. An optical plug connector includes a front housing joined to a rear housing with a plug lens spring loaded within the housing and with alignment features comprising two flat alignment surfaces orthogonally oriented relative to each other.
