Fiber Price Volatility Is Here to Stay

On June 29, 2026, CRU, the globally recognized commodity research authority, announced a fundamental change to its optical fiber price assessment service. The global bare fiber price assessment cycle has been shortened from bi-monthly to monthly, with expanded monitoring that now includes G.657.A1 and G.657.A2 bend-insensitive fiber categories.

Behind this seemingly technical adjustment lies a clear message: the era of stable, predictable fiber pricing is over.

From 32 Months of Decline to a 263.0 Spike

Between 2023 and early 2025, the global fiber market was stuck in a prolonged downturn – weak demand, oversupply, and relentless price competition. CRU's global bare fiber price index fell for 32 consecutive months.

Then everything changed.

The market bottomed out in May 2025. By November 2025, the index had recovered to 88.7. But 2026 brought an explosion: the index surged to 107.9 in January, then skyrocketed to 263.0 in March – the largest single-month spike since CRU began tracking in 2017.

What drove this? A convergence of forces:

AI and data center demand – Hyperscale computing and AI infrastructure are consuming fiber at unprecedented rates

Fiber drone applications – Emerging use cases adding new demand streams

Preform shortages – Upstream production capacity stretched thin, raw material costs rising

Supply shifts – Chinese manufacturers pivoting capacity toward high-margin G.657 series bend-insensitive fibers, tightening supply of traditional G.652.D

The impact has been global – China, India, Europe, and the US all affected by interconnected supply chains, raw material constraints, and regional demand surges.

What This Means for Your Procurement Strategy

CRU's shift to monthly assessments is not just about faster data. It reflects a fundamental reality: fiber prices are no longer driven by a single regional factor. Supply chains, raw material availability, and policy variables are now intertwined, creating much wider and faster price swings.

For network operators, system integrators, and cable buyers, this means:

Shorter price lock windows – bi-monthly quotes are no longer reliable

Greater need for real-time market intelligence – to time procurement decisions

More strategic fiber selection – as different fiber grades now have distinct price trajectories

One of the most significant developments is the growing divergence between G.652.D and G.657 series fibers. As Chinese manufacturers shift capacity toward higher-margin bend-insensitive fibers, traditional G.652.D supply is tightening. At the same time, G.657.A1 and G.657.A2 fibers are gaining share rapidly in compute-intensive data centers, AI server farms, and advanced FTTH deployments.

Adapting Your Fiber Selection Strategy

In this volatile market, the choice of fiber type has become a strategic decision – not just a technical one.

Indoor Cables and Patch Cords: The G.657 Advantage

For indoor fiber optic cables and fiber optic patch cords, the case for G.657 series fibers has never been stronger:

Tighter routing – G.657.A1 and G.657.A2 fibers handle sharp bends and confined spaces with ease, essential for crowded data center racks and FTTH installations

Future-proofing – As networks scale to higher densities, bend performance becomes critical

Installation flexibility – Reduced risk of signal loss during installation and maintenance

The expanded monitoring of G.657.A1 and G.657.A2 prices by CRU reflects their growing market significance. As these fibers become more mainstream, buyers who understand their advantages will be better positioned to optimize both performance and cost.
