Thorlabs offers patch cables with a coreless end cap and an antireflection-coated FC/PC connector on one end. The AR coating provides 0.25% reflectance in the 1030 - 1120 nm range and minimizes reflections when launching out of the fiber into free space.
The end cap reduces the power density to a level below the damage threshold, making the FC/PC connectors on these patch cables capable of handling CW powers of up to 15 W.
