摘要： A method for making an optical fiber transmission apparatus for limiting the optical modes which were emitted from a source in such a way to impinge on an optical fiber to extract a high bandwidth from the fiber. The apparatus includes a lens or aperture to control the angle and distribution of light launched into the fiber. The apparatus achieves reproducibly high bandwidths in large core step-index optical fibers of short transmission length distances. The lens or aperture introduces light from the source into the fiber at an angle at which substantially no intermode delay occurs as the light propagates down the fiber. An integral fiber optic coupling assembly that includes an optical electronic component receptacle, the lens and/or aperture, and an optical fiber connector interface which provides low cost easy to manufacture assembly is also disclosed. A unitary plastic housing provides the function of a lens and mechanical reference or locating features for the light source and optical fiber.

摘要： Attachment of electronics to optical devices is made by supporting the optical devices on a heat spreader card and the electronics on a separate circuit card. Each card has at least a first major surface, with an optical transducing subassembly mounted perpendicularly from the major surface of the heat spreader card. Electronics, except for transducing elements, are placed on the circuit card. The only direct attachment between the circuit card and the heat spreader card is one or more flexible cables attached to the respective major surfaces. This arrangement mechanically isolates the circuit card from the heat spreader card. The flexible cables include electrical conductors held positionally in a polyimide matrix, which provides for thermal isolation of the heat spreader card and the circuit card.

摘要： An optical fiber link card communication module, and process for fabricating the module, where the module provides a parallel electrical interface to the user, facilitates high speed serial transmission of data over an optical data link, and contains a plurality of converters for performing conversions between both electrical and optical signals. A preferred embodiment of the invention contemplates fabricating the optical communication module on a single multilayer card with all the transmitter electrical components being located on one side of the card, all receiver electrical components being located on the other side of the card, and the transmitter and receiver components being separated by shielding layers in the card. By using two transmitter/receiver pairs (with the transmitters and receivers being located on respective sides of the card) an embodiment of the invention provides for double full duplex communications.

摘要： An optical communication signal source package and assembly for coupling optical signals to the end of an optical fiber includes first and second semiconductor laser diodes capable of being operated in a redundant fashion for increased reliability or to provide wavelength division multiplexing for increases in bandwidth and information carrying capability. The laser diodes are supported with their mounting flanges in a common plane and are oriented to provide parallel beams of polarized light having perpendicular E-field vectors. A connector carried by the support positions the optical fiber at the target area where an optics system focuses the light beams. An optical coupling device such as a polarizing beam splitter or a holographic beam separator is responsive to the orthogonal light beams to direct both light beams toward the optical fiber with minimum decrease in amplitude. The package includes no moving parts or highly frequency selective components. The package is employed in a compact communication signal coupling assembly permitting short electrical lead lengths and high circuit density.

摘要： An optical fiber link card communication module, and process for fabricating the module, where the module provides a parallel electrical interface to the user, facilitates high speed serial transmission of data over an optical data link, and contains a plurality of converters for performing conversions between both electrical and optical signals. The module further includes edge mounted optical components having leads mounted on the surface of a card (as opposed to standard pin-in-hole type leads) to minimize lead capacitance and inductance from the optical components to the card electronics, on board card control means for the converters and safety shut down means on the same card as the electrical and optical components.
