1. A dust and port identification cap for fiber optic adapters, comprising:
an opaque or translucent elongate body having a first end and a second end opposite the first end, and at least two sides extending at least partially between the first end and the second end;
the elongate body comprising a fixed flange disposed between the first and second ends of the body, the flange having first and second flange surfaces extending laterally outward from at least the two sides, wherein the first flange surface is on the flange opposite the second flange surface;
a knob portion at the first end extending outward from the first flange surface, the knob portion including a bulbous structure at the first end and a neck extending between the first flange surface and the bulbous structure, and wherein the neck has a perimeter dimensionally smaller than a perimeter of the bulbous structure;
an adaptor portion at the second end extending outward from the second flange surface in a direction opposite the knob portion, wherein the adaptor portion has an opening for receiving a fiber optic cable therein that continues inward from the second end toward the first end and that terminates at an inner surface between the second end and the second flange surface, the elongate body having a continually solid central core between the inner surface and a point on the knob at the first end farthest from the inner surface.
