Driven by the growth of laser market Diamond has developed two new F-SMA connector types based upon free standing fiber technology capable of withstanding optical powers of up to several hundreds of watts, to be deployed in industrial, medical, military, and telecom environments. The two options are offered in a mode-guider and in a mode-stripper version each one applicable to fibers from 100 µm up to 1000 µm core diameter. The mode-guider version allows all the modes to propagate with minimum attenuation leading to a higher power transmission and a lower heat dissipation. The mode-stripper version removes the unwanted cladding modes from the fiber.
