Navigating High-Speed Transceiver Challenges: Evolution, Impairments, and Dispersion

Francois Marcotte from EXFO presents on high-speed transceivers, covering their evolution, technical aspects like NRZ and PAM4 modulation, and the importance of FEC for error correction. He discusses different transceiver types (SFP, QSFP, CFP) and their applications, highlighting the challenges of heat dissipation and power consumption. Marcotte also explains coherent optics, CMIS, and potential issues like thermal noise and dispersion (chromatic and polarization mode dispersion). The presentation concludes by emphasizing the importance of signal-to-noise ratio and offering tools for testing transceiver performance, followed by a question from the audience regarding heat and power constraints with ZR and ZR plus optics.
