Hi Guys,

I got a  SFP+ DAC cable, but also wanted to fiber connection with the peer to peer MNPA19-XTR for a potential longer run. What 10Gbe fiber module do you recommend and cable? There seem to be a lot of choices on ebay cisco, HP, IBM 850nm v.s 1610nm etc?

 

Some parts and explanation on differences would be fantastic

 

Thanks very much in adavnce

I would try and get hold of the supported ones,  some cards are funny about which transceivers they will take.  Mellanox ones are here :-

I assume they will be compatible with the cards you have.

 

Guessing you will not need LR (Over 300M fibre, 1610nm) so I would go for SR (850nm) since they tend to be cheaper......   Make sure you buy the right fibre too.

Chris, would these Cisco Units work?

Google suggests Mellanox cards aren't fussy so those Cisco ones should work.....  but I only personally have experience with Cisco stuff in Cisco network gear so ymmv  

 

You will need 850nm OM3 Multimode fibre for the SFP-10G-SR.

 

 

 

 

Would om4 work ? What's the difference between om3 and 4?

I bought this I suppose I can change if it doesn't work

OM4 should work too,  I think you can get slightly better range out of OM4.

thanks so much, really appreciate the feedback and advice
