We have maybe 1:50 DOA, but they’re so cheap, we just throw them out because it’s not worth the RMA.
That said, I can’t remember the last time we’ve had any of these fail in the field, or have had any issues with variablity in TX/RX power. We have tens of thousands of these in the field, from 100Mb Bidi to 100G-LR and everything in between, including *WDM up to 80KM. > On Sep 20, 2019, at 8:31 AM, Nicholas Warren <[email protected]> > wrote: > > Anyone have experience with fs.com's lasers?
