Patch panel assemblies (150) that contain patch panel modules (50) for use in optical fiber telecommunication systems are disclosed. One of the patch panel assemblies includes a front mounting frame (210F) and at least one internal mounting frame (210I) that support a plurality of patch panel modules. The patch panel assembly also includes a hinge assembly (224) configured allow bend-insensitive fiber cables (70) to be routed therethrough. One of the patch panel assemblies includes a housing (152) with a drawer (270) that supports a plurality of patch panel modules. The patch panel modules employ bend-insensitive optical fibers (12C) to connect front and rear ports (92, 98) so that the patch panels have a reduced size as compared to conventional patch panel modules. The patch panel assemblies include a cable distribution box (300) that can store excess cable and that assists in routing bend-insensitive fiber optic cables within the patch panel assembly interior (200) in order to connect to select patch panel module jacks (90).
