Abstract
Fiber optic terminals and fiber optic networks having variable ratio couplers are disclosed. The fiber optic terminals comprise a shell having a portion of a variable ratio coupler disposed therein. The variable ratio coupler comprises an optical input, a first optical output, a second optical output and a control. The control may be adjusted for changing an output power level between the first optical output and the second optical output.
Claims52
A 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;
- 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.

A 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, wherein a portion of a first optical waveguide of the first optical output and a portion of a second optical waveguide of the second optical output are fused together to form the coupling region, and the control is configured for moving a portion of the coupling region for changing the output power level between the first optical output and the second optical output;
- and
- a plurality of output connection ports.
