Multiple signal fiber, optical pump-signal combiner

An optical pump-signal combiner, comprising:

• a first end;
• and
• a second end, wherein:
• at a first cross-section of the optical pump-signal combiner associated with the first end, the optical pump-signal combiner includes:
• a capillary,
• a plurality of signal fibers that are disposed within the capillary, and
• a plurality of pump fibers that surround the capillary;
• and
• at a second cross-section of the optical pump-signal combiner associated with the second end, the optical pump-signal combiner includes a unified fiber that includes an outer combined-cladding, a combined-pump core, an inner combined-cladding, and a combined-signal core.
