hello, Is there anyone that could tell me, what are the codes (Part Number) of Extreme CWDM SFPs ??? I.e. Extreme SX SFP has Part Numer FTM-8012C-SL (by FIBERXON INC.) How does original Extreme SFP's behave with diagnostics ? Is there any possibility to read RX signal level from command line ? Regards, Marcin
