A fiber optic RF signal distribution system has a plurality of antenna stations, each station including an RF antenna. A central RF signal distribution hub receives and transmits signals external to the system. A pair of optical fibers connects each antenna station directly to the distribution hub with the connections being in a star configuration. A connectorized laser module permits direct coupling of a distributed feedback semiconductor laser to the end of each optical fiber without an intervening connector. The module accepts an APC connector with the angled end of its optical fiber in an aperture plane in a connector housing. A distributed feedback laser is mounted in the connector housing with a lens for illuminating the aperture plane and hence, the end of the fiber at an acute angle to the axis of the fiber. Furthermore, the illumination is defocused at the aperture plane for loose optical coupling to the fiber and minimized reflection to the DFB laser.
