I've been trying out FS transceivers. Nothing fancy, just 10Gb LR SFP+ for data centre interconnects etc. Out of 8 deployed there have been 2 where the link has failed, then the reported Tx power from DOM has shown as -40.0 dBm - one shortly after deploying, one after ~2 months. Worse still it's intermittent, they have come back to life afterwards. fs support think this is faulty modules rather than a switch problem.
I wondered if anyone else is seeing a similar failure mode, or what sort of failure rate you're seeing? (FS themselves are claiming <1.5% but then they would, wouldn't they..) Should I just buy flexoptix? They are over twice the price though it doesn't take many train tickets to London to cover that ..
