Abstract

We propose full-single λ operation under normal conditions and an ONU-side Fresnel antireflection for bypass and backup path switchable point-to-multipoint systems. The 4ONU optical coherent system provides full-duplex fiber transmission without power penalty using wavelength conversion and shared link switching for primary link failure.
