This is kind of a hack but probably would work: http://www.10gtek.com/qsfp-extender <http://www.10gtek.com/qsfp-extender> One of these on each end with 10G ZR or 80km DWDM optics. _______________________________________________ juniper-nsp mailing list juniper-nsp@puck.nether.net https://puck.nether.net/mailman/listinfo/juniper-nsp
