Abstract: A fiber optic link platform in a miniature card cage configuration that is designed for installation into conventional floor and wall boxes. The platform of the present invention comprises a plurality of contiguously mounted fiber link communications modules in a ruggedized card cage, as well as a common power supply module that provides the appropriate voltage and current to power all of the remaining modules. The fiber optic link platform typically uses from one to many multimode or single mode optical fibers depending on the communication function and the number of transmit or receive units. The module/card cage configuration permits selections of those communications functions likely to be utilized at each floor box location.
