Comparison of ONU Optical Network Unit NRZ Lifespan
This article helps network and facilities engineers compare PAM4 modulation optical transceiver options versus NRZ modulation, using practical constraints from leaf-spine fabrics, real switch compatibility realities, and measured optical behaviors. When a data center upgrades from 100G to 200G or expands 400G links, the transceiver choice often becomes the hidden bottleneck: link budgets, power per port, optics sourcing, and failure modes. Understanding the lifespan of an ONU is crucial for network operators and users alike. PAM4 sends two bits in each symbol. This makes data move twice as fast as NRZ.
