This seems very similar to Poet technology? (ADVA)

The   photonic   layer   provided   by   our   FSP   3000   OLS   constitutes   the   core   of   your   transport   network   and   supports   functions   such   as   wavelength   multiplexing,   wavelength   switching,   amplification,   gain   equalization   and  fiber  impairment  compensation.  The  terminal  layer  sits  hierarchically  above  the  photonic  layer  and  is  where  transmission   modulation   formats   are   assigned.   With   disaggregation,   wavelengths   can   originate   from   any   DWDM-compliant transmission and routing equipment. It no longer prevents you from taking advantage of different technology  lifecycles,  which  are  typically  five  to  seven  years  for  the  OLS  and  two  to  three  years  for  the  terminal  layer.Open and programmable software  architectureStandardized modeling of network elements is the ultimate goal to provide fully interoperable programmable network functions.  The  drive  for  open  optical  architectures  also  means a move away from closed, per-vendor, per-product management  and  control  systems.  With  native  support  for  YANG  modeling,  NETCONF/RESTCONF  protocols  and  open  APIs,  the  OLS  of  our  FSP  3000  can  be  consistently  managed  and  controlled,  thus  minimizing  your  OPEX.  Common, open and programmatic northbound interfaces and   protocols   abstract   your   network,enabling   control   by    third-party    SDN    applications,    creating    a    unified    networking  view  and  speeding  up  integration.  They  are  a  mandatory  component  when  operating  OLSs  in  your  network infrastructure.Driving open and disaggregated packet-optical transport1.
