Options for Data Centre Interconnect#

Matthew Hayes

• Why: DCI is a named core interest, and NZ/ANZ is seeing genuine DC-to-DC demand growth from hyperscaler and AI service buildout. A structured comparison of DCI approaches is directly useful for interconnect planning.
• What: A survey of common DCI approaches, from physical-layer solutions (fibre/DWDM) to higher-layer technologies, with how each works and the pros and cons of each, framed by ANZ market dynamics (from abstract only).
• How: Comparative walkthrough of interconnect models rather than a single solution — the abstract does not name the specific technologies, so the depth depends on the talk.
• Where applicable: DC operators and interconnect providers generally; not org-specific. Likely most valuable as a decision framework for choosing between dark-fibre/own-optics versus higher-layer managed options at different distance/capacity points.
