Formally announcing what is perhaps the least well-kept secret in the optical industry, Acacia (now a part of Cisco) publicly described its upcoming 1.2Tbps solution this week. Jannu is a 5nm, 140GBaud, single carrier DSP designed to enable transmission of up to 1.2Tbps per wavelength. Acacia also announced a pluggable coherent module built using Jannu and advanced packaging of silicon photonics-based optics. General availability is expected in early 2023.
