US Patent 10267992 Fiber launcher

An optical fiber launcher assembly can include a low precision fiber array that outputs a plurality of optical signals from a given side that are input into an opposing side. The optical fiber launcher assembly can also include a corrective optic aligned with and spaced apart from the low precision fiber array. The plurality of optical signals output from the low precision array to the corrective optic have a given trajectory and optical signals output from the corrective optic have a substantially parallel trajectory different from the given trajectory.
