Hello colleagues, >From time to time Gigabit-Fiber-Ports on our old BI8GMR-Jetcore-Managementmodules are dying. In most cases they're starting to cause crc-errors which can be seen as rx-errors on the devices connected to them. Other ports are completely dead and don't bring up any link at all.
I have heard that this is "normal" because the lasers on those modules are so old and are reaching their end of life. Is there a cheap way to replace them? What about the B8GMR3-Modules: are they affected too? I'm thinking about replacing the B8GMRs with B8GMR3s because they are cheap on the grey market - but this would only make sense if they're not affected. Thanks, Gunther
