A cable connection system (100, 200, 300) includes a coupling housing (110, 210, 310) defining at least a first port (112, 212, 312); a printed circuit board (120, 220, 320) coupled to the coupling housing; and a communications component (130, 230, 330, 360, 400, 500, 550) sized to be received at the first port of the coupling housing. The printed circuit board (120, 220, 320) includes a light source (125, 225, 325). At least an indication section (135, 235, 335, 365, 450, 515) of the communications component (130, 230, 330, 360, 400, 500, 550) includes (e.g., is formed from or is coated with) a light transmissible material. The indication section (135, 235, 335, 365, 450, 515) is aligned with the light source (125, 225, 325) when the communications component (130, 230, 330, 360) is received at the first port of the coupling housing so that light emitted from the light source (125, 225, 325) illuminates the indication section of the communications component (130, 230, 330, 360, 400, 500).
