All links will be local (<1ms RTT) except link to DE-CIX where we taking 10G via 3rd party DWDM and RTT is around 4-5ms. > As a general principle, I'm not convinced that running ER/ZR SFP+ optics is > a good idea. I think about ER as I have one node where fiber distance is around 24KM. LR optics will not handle this at all. In the past I saw LR20 (X2/XENPAK/XFP) optics - LR but with increased power budget to 20KM. I'll check is it available at SFP+ form faction.
