ABSTRACT:
A connector assembly (10) for connecting a laser diode (14) and an optical fiber (12). The assembly (10) includes an optical connector subassembly (26) having an input for collecting optical energy emitted by the laser diode (14) and an output for transmitting a beam of the collected optical energy to the optical fiber (12), and attenuation means (24) between the input and the output for reducing the power of the beam of collected optical energy at the output to be transmitted to the optical fiber (12). A connector assembly of the present invention is effective in transmitting energy from a light source to an optical fiber with the same accuracy of alignment as a coupling of an optical fiber to an optical fiber; and, at the same time, is effective in controlling the power of the transmitted energy to protect against accidental injury due to inadvertent viewing of the light source when the optical fiber is disconnected from the assembly and to control the power of the optical energy entering the optical fiber.
