Hollow Core Fibre - Nothing is better than glass for guiding light#

Steve Jones

• Why: Hollow-core fiber is the most-watched optics disruption (ultra-low latency, low nonlinearity), and the title reads as a deliberately contrarian, pro-solid-glass take — exactly the skeptical operator perspective worth hearing before buying into the hype. Pure PM optics territory.
• What: An assessment of hollow-core fiber versus conventional solid glass fiber for guiding light. (title only)
• How: Presumably a physics-and-operations comparison — latency, attenuation, nonlinearity, cost, and deployment maturity; verify the framing in the deck.
• Where applicable: Long-haul, subsea, and latency-sensitive DCI routes; the practical constraints are reach, cost, and maturity of supply.
