1. A field-configurable optical device comprising:
a housing defining an enclosure;
an input port located at the housing;
a pass-through port located at the housing;
a plurality of output ports located at the housing;
a splitter disposed within the enclosure and comprising one or more splitter inputs and a plurality of splitter outputs coupled to the plurality of output ports;
a plurality of couplers within the enclosure, each coupler comprising an input, a first output, and a second output, wherein:
each coupler has a power splitting ratio between the first output and the second output that is different from other couplers of the plurality of couplers; and
the second output of at least one coupler of the plurality of couplers is in optical communication with at least one splitter input of the one or more splitter inputs;
an input port fiber optic jumper assembly within the enclosure, wherein the input port fiber optic jumper assembly is configured to selectively connect the input port to the input of an individual coupler of the plurality of couplers; and
a pass-through port fiber optic jumper assembly within the enclosure, wherein the pass-through port fiber optic jumper assembly is configured to selectively connect the pass-through port to the first output of the individual coupler of the plurality of couplers,
wherein moving the input port fiber optic jumper assembly and the pass-through port fiber optic jumper assembly from a first coupler to a second coupler of the plurality of couplers changes the power splitting ratio of the field-configurable optical device.
