Where to Catch a Bad Optical Engine in Co-Packaged Optics
When a pluggable transceiver fails, a technician pulls it from the faceplate and fits another. When an optical engine fails inside a co-packaged switch or accelerator, it can take the whole package with it, including a very expensive piece of silicon that was working perfectly. That one difference explains most of what is unusual about testing co-packaged optics (CPO). The industry's answer is the known good optical engine: prove the engin…
