Network upgrade - optical fibre densification
What it is
Optical fibre cable manufacture spans preform, fibre drawing and cabling, with integration across all three the key cost differentiator. Demand comes from 5G densification, fibre to the home, data centre interconnect and the BharatNet rural broadband programme
Global fibre prices have been depressed by Chinese overcapacity
Impact on industries
- Backward integration into preform is decisive, since it is the highest-value step and determines whether a cabler earns a spread or a conversion fee
- 5G densification and FTTH both require far more fibre per subscriber than legacy networks, so demand grows with network architecture rather than subscriber count
- BharatNet provides policy-backed rural volume that is independent of private operator capex cycles
- Chinese overcapacity depressed global fibre pricing, and demand is tied to telecom capex constrained by operator balance sheets
