I recently learned about this S+RJ10 copper SFP+ module and it has changed my plans for adding 10gb networking to my two workstations. I already bought the cards (intel x540-T1) and I already have the switch (Quanta LB6M), I just need the S+RJ10 modules now but they seem really hard to find, especially at the $65 price! I did find them on streakwave.com but I have never used them and resellerratings has some horrible reviews of them, so I would like another option.
