SDM-enabled optical network
Massively parallel transmission and flexible
operations are essential toward 1Pbps class
optical networks with Space Division Multiplexing
(SDM).

The Dynamic MAC
The Dynamic MAC allows massively parallel transmission
over 400 optical channels and skews handling caused by
different wavelengths, fibers, and routes.
The Dynamic MAC enables flexible traffic by routing and link
bandwidth control with gRPC.

By using gRPC-Web and envoy
(Proxy), it is possible to operate
from a browser.
