China Optical Fibre Industry — Monthly optical fibre price tracker: China prices remain elevated while overseas prices catch up

Pricing: in Sep 2026, China's G657.A1 bare fibre spot price fell slightly MoM while the US price continued to rise, with overseas prices catching up to elevated China levels; European prices also rose. On demand, CRU estimates show China's optical cable consumption declined YoY in Q3 2026 on subdued telecom demand, elevated fibre pricing and expiring telco contract purchases, whereas US demand grew strongly driven by telecom network and hyperscale data centre expansion, with Europe, ASEAN and LatAm showing stable blended growth. On industry updates, Chinese players announced new capacity expansion plans for fibre preform and specialty fibre and connectivity products such as CPO, which does not change our view of limited fibre oversupply risk; in the US, Verizon and AT&T announced multi-year, multi-billion-dollar deals with Corning to secure fibre supply. On valuation, we remain positive on the China optical fibre sector and reiterate our Buy rating on YOFC (H) and Neutral on YOFC (A);
