Global Optical Switches and Data Centre Battery Markets Set to Reach $20.6B, $10.5B by 2035

A market research firm projects the worldwide optical switches market to grow from $7.05 billion in 2025 to $20.60 billion by 2035, representing a compound annual growth rate (CAGR) of 11.36 %. Growth is driven by expanding AI workloads, cloud‑computing services and the need for high‑speed, low‑latency optical networking. Technological advances such as silicon photonics, photonic integrated circuits and software‑defined networking are expected to boost adoption. Leading suppliers include Lumentum, Cisco, Huawei, Nokia, Broadcom and others.

The same source forecasts the global data‑centre battery market to rise from $3.98 billion in 2025 to $10.47 billion by 2035, a CAGR of 10.16 %. Rising demand for reliable backup power in AI‑intensive, hyperscale and edge data centres, together with renewable‑energy integration, is fueling the market. VRLA batteries currently hold the largest share, while lithium‑ion chemistries are slated for the fastest growth. Major players listed are Schneider Electric, Vertiv, Eaton, ABB, Huawei and several others.
