Limited public evidence
• YOFC jumps over 30% to record high in Hong Kong
• Fibre pricing shift signals stronger upstream leverage across supply chain
The fact
Fujikura raised prices for data centre interconnect cables by about 30% and lifted earnings guidance. Corning is expanding optical fibre production after signing a multi-billion-dollar supply deal with Amazon on 8 June. YOFC rose more than 30% in Hong Kong trading to a record high of HK$285. Global optical fibre preform supply has been unable to meet demand since January, with capacity near full utilisation. YOFC has ranked first globally in fibre preforms, optical fibre and optical cable output since 2016.
The assessment
AI data centre demand is transmitting into the optical interconnect layer, with pricing power shifting upstream as fibre supply tightens. Fujikura's price actions and Corning's Amazon deal show hyperscale buyers locking multi-year fibre commitments before capacity opens up. YOFC's record high reflects how quickly the market is repricing connectivity hardware as a critical bottleneck. For BTW readers, optical fibre availability determines how much bandwidth can actually move between data centres—the physical layer of internet interconnection is now competing with chip supply for capital.
What to watch
Whether fibre price increases extend beyond DCI cables into broader optical categories. How other hyperscalers respond to Amazon's multi-year fibre supply lock.
