Overview

Optical transport networks power the digital economy-but performance and predictability only happen when great photonics meets great service management. ITIL for Optical Transport Network Excellence shows engineers and leaders exactly how to fuse ITIL(R) practices with DWDM/OTN realities so operations become not just fast and resilient, but also predictable, auditable, and continually improving. Written as a toolkit you can open anywhere, the book avoids rigid chapters. Jump straight to what you need-designing trustworthy services, running high-stakes operations, or rolling out changes safely-and adopt field-tested artifacts right away. You'll see ITIL's language of value, practices, and the Service Value System translated into day-to-day optical work: planning wavelengths, operating multivendor ROADMs, restoring service after fiber cuts, hardening the management plane, and proving compliance. Who it's for Network & transmission engineers who want repeatable models that cut MTTR and raise change-success rates. NOC leaders and service managers who own SLAs and customer trust. Security, governance, and audit teams needing defensible controls for OTN management planes and data in transit. Executives and program managers aligning investment to outcomes across vendors. What you'll be able to do Build a shared foundation (SVS, guiding principles, utility vs. warranty) that lets mixed v3/v4 environments move forward together. Design services people can trust-clear latency/jitter targets, ODUflex profiles, diverse routing, and acceptance criteria. Operate with clarity under pressure-incident/request practices tuned to BER spikes, OSNR degradation, and control-plane faults. Stop repeats-problem management anchored in TCM/FEC/power telemetry and a living known-error library. Make change safe and fast-MoPs, canary upgrades, and automated rollbacks across line systems, transponders, and NMS/SDN software. See and prove what matters-event correlation to root cause, SLO/SLA reporting people understand. Why it matters now Adopting even a subset of these practices lowers risk, increases reliability, clarifies accountability, and creates measurable, customer-visible improvement-turning every wavelength you light into capacity and confidence.
