But when these twinax cables are "SFP-to-SFP" connector, you'd think they would be more forgiving about the copper details between them, and just conform to the SFP+ attributes at the business ends. Still somewhat of a mystery, as there is no proper "twinax" standard like there is with 10G-SR, LR, LRM, ER, etc. Jeff _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
