Semi Doped(@semidoped):1.6T LPO from Linktel No DSP, and you can see pre-FEC BER is about 1e-9. Temps stay cool, at 35C due to no DSP The deployment is LPO is expected to be limited to specific use cases. LPO makes it difficult for the link to work with different vendors on either end. The link needs to be trained on a per port basis, and parts of the CTLE and amp are adjusted to close the links. This extra work is what LPO difficult and limits its widespread use
