There is provided fiber drop terminal ("FDT") assemblies for providing selective connections between optical fibers of distribution cables and optical fibers of drop cables, such as in multiple dwelling units. The FDT assemblies include a mounting plate that enables the FDT to be conveniently and securely mounted to a generally vertical surface, such as a wall. The mounting plate is structured such that the base of the FDT must be removed before the mounting plate can be removed, and the cover of the FDT is structured that neither the base nor the mounting plate can be removed without first removing the cover. The cover may be selectively locked to the base and/or mounting plate with a locking fastener; therefore, only technicians able to remove the locking fastener may remove the cover, base, and/or mounting plate of the FDT assembly.
