METHOD AND DEVICE FOR CONSTRUCTING AND OPERATING A MODULAR, HIGHLY SCALABLE, VERY SIMPLE, COST-EFFICIENT AND SUSTAINABLE TRANSPARENT OPTICALLY-ROUTED NETWORK FOR NETWORK CAPACITIES OF GREATER THAN 1 PETABIT(S)

摘要

A method for setting up, operating and/or scaling a modular optically routed transport network includes: providing a quasi passive Optical Transport Network (OTN) core network according to ITU-T G.709 with N network nodes at the core network edge; providing at least one active component in each network node for the transmission of data over the core network; and changing at least one of the at least one active component in at least one network node for scaling the network. The at least one active component is an optical transceiver comprising digital signal processors (DSPs).
