Is this course of basic physics or NANOG mailing list ????

True, electrons have mass, but we are not 'transmitting' electrons. We are
oscilating the electrons in the media. This oscilation creats EM energy
which propogates down the media, in the form of photos, and will propogate
at some percentage of c depending upon the media.
