Dear John,

the horizontal line is the x-axis; use the option Axes->False to plot your
data:

Test = Table[{x, (1/
       2) + (Cos[2*2*Pi*x]/
        2)*(E^-(x^2) + (1/2)*0.1*E^-((x - 12)^2) + (1/2)*0.05*
         E^-((x - 27)^2) + (10^-3)*E^-((x - 280)^2))}, {x, -10, 40,
    0.05}];

ListPlot[Test, PlotRange -> All, Joined -> True, Frame -> True,
 FrameLabel -> {"Pathlength Mismatch (2\[CenterDot]m mm)", " Signal
   Strength "},
 BaseStyle -> {FontFamily -> "Garamond", FontSlant -> "Italic",
   FontSize -> 14}, Axes -> False]
