Result-ing emerging technologies, such as multi-wavelength transponders with increased rate-adaptivity and multi-band systems, significantly complicate the planning. Cisco ONP enables you to visualize their network designs. The paper discusses, how this approach can be applied to offline network planning as well as dynamic planning and provisioning of services. According to TrendForce (2026), the global AI-focused optical transceiver market is projected to grow from $16. 5 billion in 2025 to $26 billion in 2026, representing over 57% year-over-year growth — a direct reflection of the bandwidth pressure AI workloads are placing on optical infrastructure.
