  • Patent number: 10641969
    Abstract: A connector is disclosed that includes a housing and first and second attachment areas located in the housing and spaced apart from each other along the mating direction of the connector. The second, but not the first, attachment area is designed to move relative to the housing. The connector further includes an optical waveguide that is permanently attached to, and under a first bending force between, the first and second attachment areas. The connector also includes a light coupling unit located in the housing for receiving light from the optical waveguide and transmitting the received light to a mating connector along a direction different than the mating direction of the connector. The mating of the connector to the mating connector causes the optical waveguide to be under a greater second bending force between the first and second attachment areas.

In the other mode, the terminal transmits light having the second wavelength and receives light having the first wavelength. The terminal includes a steering mirror that directs light to and from a dichroic element that creates different optical paths depending on wavelength, and also includes spatially separated emitters and detectors for the two wavelengths. A first complementary emitter/detector pair is used in one mode, and a second pair is used for the other mode. The system also includes at least two ferrules. Each ferrule operates with a single emitter/detector pair. The ferrules are designed to operate interchangeably with either emitter/detector pair.

  • Patent number: 10620382
    Abstract: The invention relates to a bend limiting structure for preventing a flexible optical circuit from being bent too sharply. More particularly, the invention involves adding a bend limiting layer or layers to the flexible optical circuit and/or any housing or other structure within which it is enclosed or to which it is attached. The bend-limiting layer may comprise a plurality of blocks arranged in a line or plane and joined by a flexible film that is thinner than the blocks, with the blocks positioned close enough to each other so that, if that plane of blocks is bent a predetermined amount, the edges of the blocks will interfere with each other and prevent the plane from being bent any further. The blocks may be resilient also to provide a less abrupt bend-limiting stop.
