Traditional error free transmission in optical comms is 1E-15 BER. I can't access the EPON standard right now, but my experience with other IEEE standards would tell me they're probably guaranteeing 1E-15 for worst-case optical link. This link is pretty close to optimal, so 400G of data is nowhere the amount to say anything with certainty about the BER of the channel.
- zamadatix 6y agoIEEE only guarantees 10^-12 which is almost certainly why 1st gen 25G products released exactly when they were able to hit that. My estimate a 2m 10G DAC from 2017 would have a BER of ~10^-18 is from personal experience (As unlikely as it sounds I actually have done extensive testing 7 of the exact model server and NIC in our lab purchased about the same time, different switch though) not derived from the 400 GB transfers in the paper.
