Engineer the Next Generation of High-Capacity Optical Networks
The Certified Optical Network Engineer (CONE) program is an intensive five-day masterclass designed for senior telecom, hyperscale, transport, and optical networking professionals. Building upon foundational networking principles, CONE explores the intersection of coherent transmission physics, electronic digital signal processing, advanced modulation, and software-defined optical architectures.
The course addresses the engineering challenges associated with 100Gb/s, 400Gb/s, 800Gb/s, and next-generation 1.6Tb/s optical channels while examining the trade-offs between capacity, physical reach, latency, power consumption, interoperability, and cost.
Scale Network Capacity
Understand the technologies and engineering strategies used to increase capacity from 100Gb/s through 400Gb/s and 800Gb/s systems and beyond.
Optimize Optical Reach
Evaluate modulation, forward error correction, optical signal-to-noise ratio, fiber impairments, and amplification when engineering optical links.
Build Flexible Networks
Explore Flexgrid, Open ROADMs, open line systems, disaggregation, and software-defined architectures for modern optical transport.
Master the Engineering Behind Modern Optical Transport
Modern data infrastructure is moving beyond closed, proprietary ecosystems. Scaling to ultra-high data rates requires engineers who understand not only individual components, but also the complex interactions between
transmission technology, physical impairments, network architecture, software control, and operational requirements.
Coherent Transmission
Understand coherent detection, dual-polarization transmission, local oscillators, and adaptive coherent systems.
Digital Signal Processing
Examine how DSP compensates for physical impairments and enables increasingly sophisticated optical transmission systems.
Advanced Modulation
Explore high-order QAM formats, spectral efficiency, Nyquist filtering, and probabilistic constellation shaping.
Nonlinear Impairments
Understand Self-Phase Modulation, Cross-Phase Modulation, Four-Wave Mixing, and other performance limitations in high-power fiber spans.
Flexgrid & ROADMs
Explore flexible-grid spectrum allocation, wavelength selective switches, and Colorless, Directionless and Contentionless ROADMs.
SDN & Automation
Understand open APIs, NETCONF/YANG, telemetry, programmable control planes, and automated optical network provisioning.
What You Will Be Able to Do
Upon achieving the CONE certification, participants will have advanced knowledge for evaluating, designing, and planning high-capacity optical transport networks.
Implement Coherent Systems
Evaluate adaptive transceivers, advanced forward error correction schemes, and high-order modulation formats for specific link profiles.
Understand DSP
Understand how coherent detection and digital signal processing compensate for physical impairments in optical transmission.
Mitigate Nonlinear Impairments
Evaluate Self-Phase Modulation, Cross-Phase Modulation, Four-Wave Mixing, and other nonlinear effects affecting high-power fiber spans.
Architect Open Line Systems
Plan disaggregated optical architectures using Open ROADMs, white-box solutions, open line systems, and flexible-grid spectrum allocation.
Optimize Data Center Interconnects
Evaluate high-density pluggable technologies including OIF 400ZR and ZR+ for low-latency point-to-point data center connectivity.
Integrate Software-Defined Networking
Understand how programmable control planes interact with physical optical line systems to support dynamic capacity management and restoration.
