ABSTRACT:
A manifold for holding spliced optical fibers contained within fiberoptic ribbons in a secure and motionless manner. The manifold includes a “clamp” made from soft durometer material (SDM) such as high strength silicone mold-making rubber or dry polymer gel that has been partially sliced to a depth of about 75%. The manifold permits ease of insertion of a spliced optical fiber by itself, or a fiber associated with a ribbon, into, and removal from, an SDM-slice without disturbing other fibers, or ribbons, respectively, that are held in other slices in the manifold. In a particular embodiment SDM fills a four-sided hard plastic box to overflow. Slices in SDM are parallel to each other. The box has a hinged cover to exert pressure on overflow SDM material when the cover is closed to increase enveloping force on splice-junctions of embedded bare-glass optical fibers and on the ribbons containing those fibers. The ribbons, containing their embedded fibers, exit the box, left and right, via angled or skewed cut-outs in the side walls of the box.
