AI networks are growing, and new optical technology could deliver higher speeds, lower power use, and more data capacity without needing larger systems.
Coherent Corp has expanded its scale-across portfolio with new multi-rail optical transport and DCI transceiver technologies aimed at supporting the growing bandwidth and efficiency demands of AI-driven networks.
At the center of the update is an enhanced compact multi-rail optical transport platform that can support four C+L band transport rails within a single 1RU in-line amplifier (ILA) card. The company says the addition of resource pooling improves power efficiency while increasing transport capacity without expanding the system footprint.
The platform is built on several of Coherent’s proprietary optical technologies, including high-power multi-port 980nm pump lasers, octal dynamic gain equalizers (DGE), compact multi-port Optical Time Domain Reflectometers (OTDR), multi-port C+L Optical Channel Monitors (OCM), and ultra-high-performance multi-port OCMs. These technologies are supported by the company’s vertically integrated manufacturing stack, which spans advanced materials, optics, specialty fiber, components, and subsystems.
Alongside the transport platform, Coherent highlighted its DCI transceiver portfolio, which includes 100G, 400G, and 800G products already in production for hyperscale and carrier-grade interconnect deployments. The company has also recently qualified 100G-ZR bi-directional (BiDi) modules designed to improve fiber utilization and support metro and regional connectivity.
Coherent is also increasing production of its nano-Integrated Tunable Laser Assembly (nano-ITLA), which delivers high optical output power and narrow linewidth performance. Combined with the company’s transport and transceiver technologies, the portfolio is positioned to support scalable AI cluster interconnects and modern DCI architectures.
“AI traffic growth is fundamentally reshaping optical transport system architecture,” said Sunny Sun, Executive Vice President – Communications at Coherent. “Our innovations reflect the strength of our optical platforms and deep vertical technology stack, enabling meaningful gains in capacity density while maintaining efficiency and reliability. We are helping network operators scale infrastructure to meet the demands of AI-driven applications.”
