摘要： The invention pertains to an optical interface employing optics (e.g., lenses) that image the beams rather than collimate the beams. More specifically, each connector at an interface includes optics, e.g., a lens, adapted to receive a diverging beam emanating from field point and image the beam to an image point at a predetermined distance from the imaging lens. A connector employing such optics may, for instance, be effectively mated to either a similar connector with the same optics or to a connector having no lens. Specifically, it may effectively be mated to a second connector having no lens via a second connector structure that places the receiving optical component at the image point of the focusing optics of the first connector. Alternately, such a connector may be effectively mated to a second connector having an identical lens to the first connector provided that the first and second connector structures are adapted to mate such that the image points of the two lenses are coincident.
摘要翻译：本发明涉及一种采用光学镜片（例如，透镜）的光学接口，其对光束进行成像，而不是对光束进行准直。更具体地，接口处的每个连接器包括光学器件，例如透镜，其适于接收从场点发出的发散光束，并将光束成像到距离成像透镜预定距离的图像点。使用这种光学器件的连接器可以例如有效地配合到具有相同光学器件的类似连接器或者不具有透镜的连接器。具体地，可以通过将接收光学部件放置在第一连接器的聚焦光学元件的图像点处的第二连接器结构有效地配合到没有透镜的第二连接器。或者，这样的连接器可以有效地配合到具有与第一连接器相同的透镜的第二连接器，只要第一和第二连接器结构适于配合，使得两个透镜的图像点重合。

摘要： A method for positioning an optical fiber having an end portion within an alignment groove of an alignment device includes orienting the optical fiber in the alignment groove of the alignment device; causing the optical fiber to elastically flex; using an interference point to assist in forming a curved profile of the flexed fiber, and using inherent elasticity of the flexed optical fiber to assist in retaining the end portion of the optical fiber in contact with the alignment groove. A connection system includes a connector, alignment device, and adapter, with an interference point on at least one of the connector, alignment device, or adapter.
