Ta konkretna wkładka wymaga quirka żeby kernel jej nie ubijał z powodu TX Fault
SFP_QUIRK_F("OEM", "SFP+ONU-XGSPON", sfp_fixup_ignore_tx_fault)
Wkładka podnosi się całkiem szybko, nic wiecej nie było potrzebne choć najbardziej umęczyłem się przez to, że dotarła do mnie uszkodzona - popękane połączenia pod układami BGA, szczególnie pamięć RAM okazała się winna.
Efekt był tak, że wyłączała się po rozgrzaniu do ok 53 stopni C, aktualnie działa przy 68 stopniach
