Abstract: A fiber termination assembly includes an optical fiber inserted into an optical ferrule disposed in an optical passageway of a heat conductive housing, the optical passageway providing an optical path aligned with the openings of the housing, the optical ferrule including a central bore concentrically disposed about the optical path and configured to receive a portion of a proximal end of the optical fiber therein, the optical ferrule and optical fiber secured in relation to the heat conductive housing with epoxy at a distal end of the optical ferrule, wherein the optical ferrule is transparent at a predetermined wavelength of light such that for light coupled into an input surface of the proximal end of the optical fiber at least a portion of the light propagating as cladding modes is stripped out of the optical fiber and transported to and dissipated in the heat conductive housing.
