Coherent's 140 Gbaud IC-TROSA is a coherent optical engine that complies with the Optical Internetworking Forum's (OIF) IC-TROSA implementation agreement (Type-2). It contains all the critical building blocks: wavelength-tunable laser, optical amplifiers, modulators, drivers, coherent mixer, photodiode array, and trans-impedance amplifiers. A micro-controller, digital-to-analog converters, and analog-to-digital converters are embedded into the IC-TROSA, providing a simple digital communication interface for all control and monitoring. The high level of integration and lower power dissipation of this 140 Gbaud IC-TROSA enables 800G ZR pluggable transceivers in QSFP-DD and OSFP small form-factors so DWDM optics can plug directly into routers and switches for IP-over-DWDM architectures.
Judge’s Comment: “This is a key technology development for the support of 800Gb ZR applications, which are expected to ramp fast in 2024 and the 400Gb thru 800Gb ZR+ applications as the ZR modules are used in more traditional applications.”
