Critical Issues for the Flexible Spectrum Network: Peter Roorda, Product and Technology Strategy, Lumentum

PublishTime：2022-11-07

●The industry is consolidating quickly on 100 G systems over a 50 GHz channel grid for the next round of core network build-outs. And, network designers are looking at developing technologies for the next generation of transmission line rates and the optical networks that will carry them.
●While there is little consensus on which modulation formats or line rates to use for the improved spectral efficiency required, there is growing agreement that the optimal spectral allocation for systems of 400 G and beyond will not align to the channel spectrums available in today’s 50 GHz systems.
●To ensure maximum flexibility when scaling their networks, carriers envision systems that not only automatically provision and switch end-to-end optical channels, but that flexibly allocate bandwidth to best suit channel line rates and modulation formats.
●This added network flexibility, combined with improved network OSNR required for very high line-rate transmission, would let carriers efficiently set up new higher-rate channels without constraints and ensure that evolving transmission technologies do not render their networks obsolete.
●The Lumentum TrueFlex™ suite of key optical networking products fully addresses these requirements for network transformation.
●This white paper briefly reviews several issues critical to making flexible grid networks a reality:
■The Wavelength Selective Switch is Key
■Limitations of Broadcast-and-Select Architectures
■Advantages of Route-and-Select Architectures
■The Role of the Optical Channel Monitor
■The Role of Enhanced Amplification
