Expansion of 5G, Fiber Networks, and High-Capacity Optical Transport Infrastructure to Accelerate Market Growth

The continued expansion of 5G networks, fiber connectivity, and high-capacity optical transport infrastructure is creating sustained demand for optical switches across metro, backbone, aggregation, monitoring, and wavelength-routing networks.

Higher mobile and fixed-network traffic requires operators to dynamically route greater volumes of optical signals while maintaining network resilience and efficient use of available fiber capacity. Further, increasing the need for ROADMs, wavelength-selective switches, optical cross-connects, protection switches, and reconfigurable optical switching systems.

• In June 2026, Ericsson reported that global 5G subscriptions had reached 3.1 billion, while 5G already carried 48% of global mobile data traffic at the end of 2025 and is expected to account for 85% by 2031. The resulting transport-capacity requirements are already driving major optical-network upgrades.
• In December 2025, KPN selected Nokia to deploy an 800G-ready nationwide IP and optical transport network in the Netherlands. Further, increasing supported network capacity from 48 Tbps to more than 216 Tbps while expanding fiber connectivity and network automation.

As 5G adoption, fiber penetration, and per-user bandwidth requirements continue rising, operators will increasingly require flexible optical-layer routing, automated wavelength reconfiguration, and scalable cross-connect capacity, supporting sustained global optical switches market growth.

MARKET RESTRAINTS

Insertion Loss and Optical Link-Budget Constraints to Limit Large-Scale Optical Switch Deployment

Insertion loss remains a key technical restraint for market growth, particularly as operators introduce high-radix optical circuit switches into AI data centers, telecom networks, and multi-stage optical fabrics. Every additional switching element reduces the optical power available at the receiver, which can restrict transmission distance, increase link-engineering complexity, and require higher-performance transceivers or amplification.

• In March 2025, Coherent introduced OCS-optimized 400G and 800G transceivers specifically as an optical circuit switch can add up to 3 dB of insertion loss beyond the loss budgets contemplated by conventional transceiver standards.

The new devices were engineered to absorb this additional 3 dB while preserving link reaches of up to 6 km, highlighting the practical challenges associated with integrating OCS into existing architectures. Even advanced MEMS solutions cannot eliminate the issue completely, with Lumentum reporting typical insertion loss below 1.5 dB for its MEMS-based OCS platforms.

Consequently, maintaining adequate optical power budgets while scaling port counts and network stages can increase component requirements and deployment complexity, restraining faster adoption of large-scale optical switching architectures.

MARKET OPPORTUNITIES

Integration of Optical Switching Technology with SDN and Open Network Architectures to Expand Deployment Opportunities

Integration of optical switches with Software-Defined Networking (SDN), open control interfaces, and programmable network architectures is creating significant opportunities for broader deployment across AI data centers, cloud networks, and next-generation telecom infrastructure. SDN enables operators to dynamically configure optical paths, automate topology changes, monitor network conditions, and coordinate optical switching with higher-layer network resources, reducing the operational complexity historically associated with photonic networks.

• In March 2026, iPronics showcased its commercially available silicon-photonics Optical Circuit Switch, which uses software-defined control to dynamically reconfigure low-latency Layer 1 connectivity for AI clusters while incorporating on-chip telemetry capabilities.

This demonstrates how optical switches are evolving from standalone hardware into programmable elements of automated network fabrics. Industry collaboration is also strengthening this opportunity.

• In April 2026, the Open Compute Project released an Optical Circuit Switching white paper contributed by iPronics, Lumentum, Ciena, and Lumotive, reflecting growing industry efforts around scalable OCS deployment in AI and hyperscale data centers.
