The combination of FS optics and Quanta switches has about a 10% jammed optic rate which makes moving them a high risk task. Not had any other issues over around 40 deployed optics in service from 6 months to 5 years. We use Flex too, again no issues in service and never had one jam on me, their physical construction is much better. Pete On Fri, 17 Aug 2018, Oliver Elliott wrote:
Interestingly I have been seeing similar failures lately, but on other 3rd party optics. Not had a failed FS.com optic yet. Typically it has been resolved by just reseating the optic.

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 ..
