Abstract

Anuj Malik (Cisco)

  • Why: Coherent pluggables in routed ports are the mechanism behind the IP/optical convergence several operators at this conference claim as their headline win. Understanding the DSP/laser internals separates real capability from datasheet numbers.
  • What: A technical breakdown of coherent pluggable technology: tunable lasers, high-speed ADC/DACs, and DSP algorithms, plus performance comparisons (data rate, reach, power) against traditional coherent solutions, with deployment scenarios and case studies (from abstract only).
  • How: Component-level walkthrough of the coherent DSP chain, then comparison of metrics and discussion of the trend toward IP/optical layer convergence.
  • Where applicable: High-bandwidth transport / WAN and DCI contexts. The "convergence" framing is vendor-aligned (Cisco Routed Optical Networking); the component physics is general.
