Capacity Planning & Margin Management for Transport Networks
Turn a demand forecast into a spectrum and margin plan, predict quality of transmission with the GSNR framework, and defend every decibel of margin on a route. Ten modules run from OSNR and GSNR first principles through spectrum, amplifiers, OTN and FEC, and protection to four full end-to-end system designs. Built for final-year students through mid-career optical and transport engineers, with knowledge checks, worked examples, and interview preparation throughout.
