SFP or SFP+ optical transceiver failure can happen in multiple recognizable ways. The most notable fault is the “module not detected” error, which describes a situation in which a switch cannot detect the transceiver. Most of the time they appear as inconsistent links, intermittent errors, unexplained flaps, or ports that simply refuse to come up. In multi-vendor environments, that usually means one thing: the compatibility chain is broken somewhere.
