The InfiniBand specification mentions the following about differential

There are a _lot_ of networks out there with non-compliant channels,
then. The spec says one thing, but the reality matters. Also, perhaps my
math is wrong, but that seems to be one error every 18 seconds or so at
FDR speeds?
If data is transferred at line rate on an FDR network, I agree that
about one error is expected about every 18 seconds.
Sorry but it's not clear to me what makes you think that there are a lot
of IB networks with non-compliant channels ?
