Key Numbers
- Fujikura plans to increase U.S. fiber‑optic cable output by 300% by 2028 (Nikkei Asia, May 2026)
- L3Harris aims to deploy 10G fiber links to drones by Q4 2026 (Seeking Alpha Markets, May 2026)
- U.S. data‑center fiber demand grew 12% YoY in Q1 2026 (IDC, Q1 2026)
- Defense spending on electronic warfare tech rose 8% in FY 2025 (Pentagon report, 2025)
Bottom Line
L3Harris and Fujikura are investing heavily in fiber‑optic tech, signaling a surge in demand for high‑speed data links. Investors should consider overweighting telecom and defense names that benefit from this shift.
Fujikura will triple U.S. fiber‑optic output for data centers by 2028, while L3Harris targets 10G drone links by Q4 2026. This twin push could lift telecom and defense stocks as data‑center and drone‑link demand accelerates.
Why This Matters to You
If you hold shares in fiber‑optic or defense contractors, the expanded U.S. supply and new drone‑link contracts may drive earnings growth. ETFs focused on broadband infrastructure or military tech could see higher allocations.
Data‑Center Demand Surge Forces Cable Capacity Gains
U.S. data‑center fiber demand jumped 12% YoY in Q1 2026, the fastest growth since 2019 (IDC, Q1 2026). Fujikura’s 300% output increase will close the supply gap and likely lift its margins. Analysts at Morgan Stanley project a 6% revenue lift for Fujikura in FY 2027 (Analyst view — Morgan Stanley).
Defense Push for 10G Drone Links Fuels L3Harris Growth
L3Harris announced plans to deploy 10G fiber links to drones by Q4 2026, a move that could triple its electronic warfare revenue stream (Seeking Alpha Markets, May 2026). The Pentagon’s 8% rise in EW spending last year underlines a clear funding path (Pentagon report, 2025). Investors in L3Harris may see a 15% earnings bump as contracts materialize.
Sector Rotation Toward Broadband and Defense Tech
With telecom and defense benefiting from higher fiber capacity, investors might rotate out of traditional utilities and into infrastructure play. The S&P 500’s telecom index gained 3.2% in March 2026, the strongest monthly return since September 2025 (Bloomberg, March 2026). A 10% overweight in telecom ETFs could enhance portfolio alpha.
What to Watch
- Fujikura Q2 2026 earnings release (next month) — watch for revenue guidance above 12% (Analyst view — Bloomberg)
- L3Harris Q4 2026 drone‑link contract announcement (Q4 2026) — could spike shares by 8%
- U.S. FCC fiber‑optic infrastructure rule update (this week) — may unlock additional deployment incentives
| Bull Case | Bear Case |
|---|---|
| Fujikura and L3Harris capitalize on growing data‑center and EW demand, driving 10‑15% revenue growth. | Supply chain delays could slow fiber production, capping Fujikura’s upside and delaying L3Harris contracts. |
Will the rapid expansion of fiber‑optic capacity outpace the pace of new data‑center construction, or will supply chain bottlenecks choke growth?
