Currently data transmission over the Internet between two client computers where both client computers are protected by firewalls is problematic, since firewalls block incoming packets. A dielectric layer is created over the structure having a top surface above the residual bump, for example, using a blanket deposition and chemical-mechanical underpolish. One or more optical fibers are used to transport the beams either before andor after they are combined. The supporting frame is formed by a plurality of longitudinal rods and a plurality of transversal rods.
