We're using QSFP-100G-SR4-S bought originally from CISCO. According to the CISCO Optics Compatibility Matrix they are suitable for the switch and they are marked as "Breakout Capable".The cable itself is not the issue yet, because the port goes to er...

Thanks for the info but this won't be of much help to us.First of all these breakouts are copper based and highly unflexible and furthermore we have to bridge distances up to 8 meters. At 25G this won't work with copper.Anyway CISCO is stating that i...
