Transimpedance Amplifiers (TIA)
High-performance TIAs for next-generation optical receivers.
Coherent’s portfolio of high-speed transimpedance amplifiers (TIAs) delivers best-in-class signal integrity, high programmable gain, and exceptional power efficiency for optical interconnects ranging from 56Gbps to 224Gbps per channel.
Designed for AI infrastructure, hyperscale data centers, and high-speed optical modules, our TIAs combine low noise performance, intelligent gain control, and advanced equalization to enable reliable, high-bandwidth optical links.
With solutions optimized for both established architectures and next-generation 800G and 1.6T transceivers, Coherent helps system designers scale performance while maintaining power efficiency.
Transimpedance Amplifiers
Coherent TIA’s are designed to achieve the best possible optical transceiver performance at low power consumption. All our TIA’s have been fully tested production grade optical transceivers. These amplifiers provide a rich set of monitoring and control features that help simplify transceiver design and help optimize transceiver performance.
