Posted  by GoPhotonics


Credo Technology, an innovator in secure, high-speed connectivity solutions that deliver the necessary energy efficiency and data rates to address the constantly growing bandwidth requirements of the data infrastructure market, announced the availability of Teal 200, a 4 x 50Gbps Transimpedance Amplifier (TIA) for QSFP56, QSFP-DD and OSFP optical transceivers and active optical cables (AOCs) that target high-volume, low-power applications in AI and hyperscale data centers. Teal 200 supports 200Gbps SR4/DR4/FR4 and 400Gbps SR8/DR8/FR8 applications that use 50Gbps PAM-4 modulation. Support for 4 x 25Gbps NRZ operation is included for backward compatibility. The Credo Teal 200 also features Credo’s industry-leading low-power dissipation.

“Transceivers, or pluggable modules, are the building blocks for next-generation connectivity at massive scale and by offering the Teal 200 as a seamless complement to our Seagull DSPs we are providing module makers with a complete solution,” said Michael Girvan Lampe, Vice President of Worldwide Sales and Marketing for Credo. “By providing our customers with a complete solution to enable new transceivers with better performance and improved energy efficiency, Credo is addressing the burgeoning growth of the AI/ML ecosystem which will be a significant growth driver for the entire data infrastructure industry.”
