A connection interface assembly, the assembly comprising:

• a base module having a front and a back, the base module including a back wall defining the back of the base module and first and second opposite side walls that project forwardly from the back wall to a front of the base module, the base module defining a module mounting location between the first and second side walls;
• a cable connection module having a main body coupled to or integral with a front wall to which a plurality of cable connection components are mounted, the cable connection module also including first and second opposite side walls that project rearwardly from the front wall, wherein the cable connection module is configured to be inserted into the module mounting location through the front of the base module;
• and
• an enclosure, the enclosure comprising a fiber tray and a cover, wherein the cover is configured to engage the cable connection module to form an interior cavity and seal the fiber tray therein.
