Edge computing using single-fiber bidirectional 400G

Home / Edge computing using single-fiber bidirectional 400G

Achieved bidirectional transmission at 400 Gb/s over a single fiber using coherent digital subcarrier multiplexing (DSCM). Employed subcarrier interleaving to effectively mitigate Rayleigh back-scattering. Another proposes the broadcast of spectral slices of a coherent spectrum to different destinations to improve efficient utilization of the spectrum, i. The modules each are configured with a pair of laser outputting two reference signals at respective different wavelengths λ10 and λ20, photonic transceiver and a.
