  19. What are the components still missing? noisy data regenerated data • Fibre devices remain major possibilities • Optical power no longer a problem! • A fs switch with mw threshold Optical transmission is still analogue! We need pulse reshaping and noise thresholding Microstructured fibres a strong contender • An optical buffer Photons still cannot be stored! We want routing in the optical domain – 40 Packet buffers ‘Slow light’ struggles to beat simple optical fibre delay lines
