Coherent Unveils 224Gbps Quad TIA for AI and Cloud Data Centers
Event summary
- Coherent launched its CHR1074 224Gbps quad-channel transimpedance amplifier (TIA) on March 4, 2026.
- The product is designed for next-generation 800G and 1.6T optical transceivers in AI and cloud infrastructure.
- CHR1074 features a fast-settling architecture with 50-nanosecond link recovery time.
- Samples are available now, with general availability expected by Q3 2026.
The big picture
Coherent's new TIA addresses the growing demand for high-speed, low-latency optical interconnects in AI-driven data centers. As hyperscale networks adopt burst-mode traffic and advanced power-saving states, traditional TIAs struggle to keep up. This launch positions Coherent as a key player in the evolving optical networking ecosystem, particularly for next-generation 224Gbps transceivers.
