Ciena — the underappreciated coherent layer As AI clusters move beyond a single building into campus and multi-site “scale-across” architectures, short-reach optics hit their physical limits. Signal distortion and dispersion make conventional detection unusable over distance. $CIEN’s coherent technology recovers both amplitude and phase, reconstructing a clean signal where others cannot. The market remains focused on the high-volume short-reach stack — pluggables, CPO, and related optics inside the data center. Coherent is the quieter, longer-reach piece that becomes essential once clusters themselves become distributed.
