http://www.nanog.org/meetings/nanog48/presentations/Sunday/RAS_opticalnet_N48.pdf See page 79. LR and below has no blindness danger even back-to-back, ER has a blindness danger but not a damage danger, and ZR you can actually damage if you don't have enough attenuation before going into the receiver. We don't even bother with shorter reach optics, after way too many issues encountered with SR and the like. It's easier (and cheaper if you have the right sources) to just buy all LR and standardize on SMF than it is to bother maintaining two inventories and mucking with orange cables even for intra-rack stuff. -- Richard A Steenbergen <r...@e-gerbil.net> http://www.e-gerbil.net/ras GPG Key ID: 0xF8B12CBC (7535 7F59 8204 ED1F CC1C 53AF 4C41 5ECA F8B1 2CBC) _______________________________________________ juniper-nsp mailing list juniper-nsp@puck.nether.net https://puck.nether.net/mailman/listinfo/juniper-nsp
