Abstract
A fiber routing tray to hold, organize, and route fiber cables from external sources to other optical modules and optical components. The fiber routing tray mechanical device comprises a fiber entry block, fiber channel slot, retention bar with fiber clamps, fiber clamping slots, curved fiber routing fence, and a fiber exit opening. A retention bar with a contoured fiber retention clamps is used to hold fiber cables in place, provide a strain relief to a fiber cable, and distribute uniform clamping force on the fiber cable preventing insertion and return losses. Curved fiber channel slots with a preferable width help route fiber cables and prevent them from overbending. In addition, these fiber channel slots control the extension and retraction distance of the fiber cables during external fiber cable assembly. A curved fiber routing fence help route fiber cables and help prevent them from over-bending and tangling inside of the fiber reel tray. An exit opening allows fiber cables to drop below the fiber tray before the fiber cables are attached to the optical devices and optical modules.
