Meet the Team
Acacia (part of Cisco) is a market leader in high-speed coherent optical transceivers, pioneering the development of coherent pluggable transceivers. Acacia’s coherent products are deployed by all hyperscalers to connect their Data Centers over distances from a few kilometers to thousands of kilometers and even in submarine networks. The emergence of AI has drastically increased the demand for Acacia’s coherent transceivers. Acacia’s coherent transceivers are also being used in space applications and are expected to be used inside data centers as interconnect speeds continue to increase. Acacia is also entering the PAM4 Client market and is expected to be a key provider of PAM4 solutions, including a 1.6T PAM4 DSP.
