A backplane, a method for making a backplane, and optical communication apparatuses. The backplane includes: a plurality of optical elements each selected from the group consisting of: (i) optical fibers, (ii) optical waveguides, and (iii) a combination thereof, where the plurality of optical elements have the same length, where the plurality of optical elements form at least one bundle, where the elements are bundled at both ends of the at least one bundle such that end portion lengths of the plurality of optical elements differ from each other, thus forming a broadcast-star topology, and where the plurality of optical elements is connected such that communication distance between at least two blades that can be inserted into the back plane is constant.
