Coherent demonstrated a co-packaged (CPO) 800G multimode optical engine for use in cost-, power-, and latency-sensitive applications such as artificial intelligence and machine learning computer clusters.
The module that features 16 channels of 50G NRZ transmitters and receivers in a 15 mm x 15 mm x 4 mm multimode CPO 800G VCSEL-based engine.
Each VCSEL is paired with another unpowered device to enable 100% cold sparing for extremely high reliability.
Prototypes of this multimode CPO engine, which are jointly developed with IBM under the sponsorship of ARPA-E, are available for immediate evaluation.
