An OSFP optical transceiver having split multiple fiber optical port using reduced amount of MPO terminations is provided that includes two adjacent sockets integrated into the optical port of the OSFP optical transceiver. The two adjacent sockets are vertically oriented with respect to the mounting baseplate of the OSFP optical transceiver, and each of the two adjacent sockets is adapted to receive an MPO receptacle that terminates the proximal end of a bundle of fibers. The OSFP optical transceiver also includes an optical connection between each socket and a corresponding lens in the OSFP optical transceiver, for transmitting optical signals received from other transceivers into the OSFP optical transceiver and optical signals generated in the OSFP optical transceiver to other transceivers.

A new fiber optic ferrule has an alignment structure on a surface through which light passes. The alignment structure is preferably in the shape of a dog bone, allowing the alignment structure to align the fiber optic ferrule in a receptacle while reducing the influence of temperature on the alignment.

An optical ferrule (200) has opposing major top (10) and bottom (20) surfaces where the bottom surface includes discrete spaced apart first (90) and second (100) platforms arranged along a mating direction of the optical ferrule (200). During a mating of the ferrule (200) with a mating optical ferrule (200′), the first (90) and second (100) platforms of the ferrule (200) slide against corresponding respective first (90′) and second (100′) platforms of the mating ferrule (200′). Upon full mating of the ferrule (200) with the mating ferrule (200′), the second platforms (100, 100′) of the ferrule and the mating ferrule remain in contact with and rest on each other, and the first platform (90, 90′) of neither ferrule makes contact with the other ferrule.

An optical connector includes a housing with a bottom wall defining a window therein, and an optical ferrule disposed in the housing and comprising opposing major top and bottom surfaces. The major bottom surface of the optical ferrule faces the bottom wall of the housing. The major top surface includes a groove and a light redirecting surface configured to receive light along a first direction from an optical fiber received and secured in the groove, and redirect the received light along a different second direction. The redirected light exits the optical ferrule though the bottom surface and exits the housing through the window, such that, when the optical connector mates with a mating optical connector including a mating optical ferrule, the mating optical ferrule prevents any of the light exiting the optical ferrule from exiting the housing of the optical connector.

A terminus for a fiber optic cable has a ferrule with a fiber stub secured in a channel of the ferrule. The fiber stub has a polished forward end face. The fiber stub extends from a rearward end of the ferrule so that a rearward end face of the fiber stub is rearwardly spaced from the ferrule. An alignment member is axially aligned with the ferrule and has a channel extending between forward and rearward ends of the alignment member. The channel includes a fiber alignment portion in which the rearward end face of the fiber stub is received. The fiber alignment portion is statically configured to receive a forward end face of the filament of the fiber optic cable in opposed relationship to the rearward end face of the fiber stub and axially align the faces to each other.

An optical fiber array device includes a substrate, a cover plate, and a ceramic ferrule array. A receiving groove is defined in one surface of the substrate. The substrate and the cover plate are coupled together and cover the receiving groove. The receiving groove includes a first groove wall and a second groove wall. The ceramic ferrule array includes at least one layer of ceramic ferrules and a number of positioning members. Opposite sides of the at least one layer of ceramic ferrules respectively abut the first groove wall and the second groove wall. Each of the positioning members is located between two adjacent ceramic ferrules.

Waveguide substrates, waveguide substrate assemblies, and methods for fabricating waveguide substrates are disclosed. In one embodiment, a waveguide substrate includes an input edge, an output edge, and at least one waveguide within the waveguide substrate. The waveguide substrate further includes at least one input alignment feature within the input edge adjacent to the input end of the at least one waveguide, wherein the at least one input alignment feature is fabricated from a material of the waveguide substrate. The waveguide substrate may also include at least one output alignment feature within the input edge adjacent to the output end of the at least one waveguide, wherein the at least one output alignment feature is fabricated from the material of the waveguide substrate.

A fiber optic coupling device comprises an elastomeric body. The elastomeric body includes first and second sides with a deformable alignment passage extending there between. The deformable alignment passage is configured to elastically center opposing first and second optical fibers. The deformable alignment passage includes a first portion that is configured to receive the first optical fiber having a first core. The deformable alignment passage also includes an opposing second portion that is configured to receive the second optical fiber having a second core. The first portion and the opposing second portion of the alignment passage are defined by a common encompassing periphery, and meet at a common location within the alignment passage to present the core of the received first optical fiber in coaxial alignment with the core of the received second optical fiber.

A factory processed and assembled optical fiber arrangement is configured to pass through tight, tortuous spaces when routed to a demarcation point. A connector housing attaches to the optical fiber arrangement at the demarcation point (or after leaving the tight, tortuous spaces) to form a connectorized end of the optical fiber. A fiber tip is protected before leaving the factory until connection is desired.

Examples described herein include optical adapters. In some examples, an optical connector adapter includes a housing with a first end and a second end, a latch assembly inside the housing, and an adapter optical ferrule. The latch assembly may include two latch arms and an engagement feature to mate the adapter to a number of optical transceiver shells. The engagement feature may protrude beyond the second end of the housing. The adapter optical ferrule is attached to the two latch arms.
