Agreed. 40GE future looks extremely bad. This gen is 25G lanes, next gen is 50G lanes. QSFP56 will support 8 or 4 lanes at 25G or 50G. So you can get perfect break-out, without wasting any capacity. Commonly today 40GE port density is identical to 100GE density, wasting 60% of your investment, just to avoid using gearboxes and retimers. -- ++ytti _______________________________________________ juniper-nsp mailing list juniper-nsp@puck.nether.net https://puck.nether.net/mailman/listinfo/juniper-nsp
