Multi-port optical connection terminals and mounting platforms and related methods designed to secure optical components inside an enclosure of the multi-port optical connection terminals are disclosed. In one embodiment, a multi-port optical connection terminal includes an enclosure comprising a base and a cover configured to attach to the base to define an interior cavity. A mounting platform defining a mounting surface for mounting at least one optical component comprised from the group consisting of at least one splice tray and at least one optical splitter to the at least one mounting surface is provided. A plurality of mounting tabs of the mounting platform are configured to extend into channels disposed in an interior wall of the base. In this manner, the mounting platform and any optical components secured thereto are secured inside the interior cavity, which may prevent damage to optical fibers and/or splices of the optical components.
