Do you see a difference in "Cisco branded > Finisar SFP" and "Finisar SFP" other than content of EEPROM?
I've one time had a Finisar-labeled and Cisco-labeled SFP in hands ... you could see they were most likely identical from the PCB routing ... We've had a good OEM/compatible place for several years now, bought something like 100+ optics in all sizes and speeds (SFP MM/SM, X2, SFP+ MM/SM), of which some have been operating for 4+ years without any glitch ... even have 3 years warranty on them, compared to the "official" 3 months from Cisco or the minimum legal warranty of 2 years for the original Cisco SFPs. Interesting side note: in a customer Nexus 5548 we've recently put some 20+ SFPs in (1 and 10G) - along with four copper 10G links for NX2248. Interestingly, the OEM SFP/SFP+ were recognized as "original" (no warning, even without "unsupported transceiver"), but the _original_ Cisco copper SFP+ link cables are shown as third party ... (I must assume they are original, as they were purchased directly from an official reseller, and the prices match up to the OIP we set up for the project). -gg _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
