1. A fiber optic terminal comprising:
a shell comprising a cavity;
a plurality of ports comprising a control port having a port opening extending from an outer surface of the terminal into the cavity and defining a port passageway along a longitudinal axis, wherein the control port is operable to receive a tool; and
a variable ratio coupler disposed within the cavity, the variable ratio coupler comprising an optical input, a first optical output, a second optical output, and a shaft, wherein rotation of the shaft by the tool changes an output power level between the first optical output and the second optical output at a coupling region.
