1. A fiber optic terminal for making one or more optical connections with external connectors, the fiber optic terminal comprising:
a shell comprising a cavity;
at least one variable ratio coupler having a portion disposed within the cavity, the at least one variable ratio coupler comprising an optical input, a first optical output, a second optical output, and a control for changing an output power level between the first optical output and the second optical output at a coupling region for tuning the output power level;
at least one input connection port configured for receiving an external optical connector, the at least one input connection port comprising a port opening extending from an outer surface of the terminal into the cavity and defining a port passageway along a longitudinal axis; and
a pass-through output connection port.
