FS QSFP28-SR4-100G possible batch issues

[Railgun]

Bit of a long shot here, but curious to know whether anyone is using these optics. If so, can you indicate whether you have any with S/N starting with G22207? Doesn't particularly matter how they're encoded.

Whether in straight 100Gb operation or breakout also doesn't matter. FEC enabled or disabled also doesn't matter.

Just curious if anyone has had any issues of any kind; flapping interfaces, inconsistent light levels, packet loss for no apparent reason...anything.

Other "batches" are operating correctly, and everything we've done suggests there's something specific to this range.

Seems I also have some C22x modules. Those were the initial ones I'd swapped to from the G222 series and also are working as expected.
