Modern networks must deliver ever-greater capacity and reliability while minimizing their environmental impact. This white paper explores how network operators can embed sustainability into every stage of the lifecycle—from design to operations to end-of-life management. It details how advanced technologies such as WaveLogic 6 optics, Navigator Network Control Suite, and universal aggregation platforms reduce power consumption, extend asset longevity, and simplify operations. With time-tested observations on energy efficiency, automation, and circular economy practices, this paper demonstrates how modernization and sustainability are inseparable priorities for building resilient, future-ready networks.
