Abstract: A plurality of n light sources are coupled to an optoelectronic module by first coupling a light detector to an optical output port of the optoelectronic module after the module is attached to a carrier member. The plurality of n light sources are sequentially moved adjacent a separate one of a plurality of n optical input ports of the optoelectronic module while pulsing the light source being moved with a low power signal sufficient to prevent failure of the light source. Each light source is permanently affixed adjacent the associated separate one of the n optical input ports when a maximum light intensity signal propagating through the optoelectronic module from that light source is detected by the light detector. A heat dissipating means is attached to a base of the carrier member capable of removing sufficient heat from the n radiation sources and the module to prevent overheating during normal operation thereof.
