    摘要： A fiber optic cassette includes a body defining a front and an opposite rear. A cable entry location, such as a multi-fiber connector, is defined on the body for a cable to enter the cassette, wherein a plurality of optical fibers from the cable extend into the cassette and form terminations at one or more single or multi-fiber connectors adjacent the front of the body. A flexible substrate is positioned between the cable entry location and the connectors adjacent the front of the body, the flexible substrate rigidly supporting the plurality of optical fibers. Each of the connectors adjacent the front of the body includes a ferrule. Dark fibers can be provided if not all fiber locations are used in the multi-fiber connectors. Multiple flexible substrates can be used with one or more multi-fiber connectors.

    摘要： A fiber routing device may include a planar structure. The fiber routing device may include a set of fiber features associated with organizing fibers for forming ribbon groups, the set of fiber features being held by the planar structure. A first end of a fiber feature of the set of fiber features may be at a first side of the fiber routing device. A second end of the fiber feature may be at a second side of the fiber routing device or may be between the first side of the fiber routing device and the second side of the fiber routing device.

    摘要： 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.

    摘要： Optical splitter modules and methods are disclosed. An optical splitter module includes a housing, a splitter chip, a plurality of optical fibers, and a base member. An outer coating of the optical fibers is stripped from the first end such that the first end has a bare portion extending from a fiber end and a stripped portion extending from the bare portion. The second end of each optical fiber has the outer coating with a diameter larger than the diameter of the stripped portion. A connector is coupled to the second end of each optical fiber. A fan-out body surrounds the coating of the optical fibers. The optical fibers are coupled to the surface of the base member such that the fiber end is positioned at the first edge of the base member. The first edge of the base member is coupled to the first edge of the splitter chip.
