Scaling Optical Networking Technologies for Next Generation SDM

1. Network traffic growth remains strong Sold WDM transponder capacity scales at ∼45% Scaling is widely supported by compute, storage, access scaling Optical transport is significantly falling behind â→ Worrisome scaling disparities ("Capacity Crunch") 2. Parallelism is mandatory log(SNR) scaling vs. linear (pre-log) multiplexing gains 3. By 2025 we will need 10T interfaces in 1P systems Massively integrated (coherent) systems: B × M × log(SNR) Scaling using WDM × SDM 4. Integration, integration, integration Holistic view of client and line interfaces integrated onto digital CMOS chips "Fiber-in-fiber-out" (FIFO) all-in-one transport processor solutions.
