[AusNOG] 100G/200G/400G coming down the pipe (so to speak)

[Darren Ward (darrward)]

Absolutely :)

Again keeping non vendor, you'll see that the release of single channel
40G and 100G DWDM short haul optics (haven't seen any plans above 10G
for CWDM from anyone as yet) for their routing/switching/datacentre
products to connect at least metro distances without requiring whiz bang
long haul pieces using the specialised transponder/muxponder modules

The point regards spectral use then becomes more important as passive
filters are fixed width filters with no flexible spectrum or switching
capability that doesn't involve sneakernet ;)

At the risk of going low-rent, I'd be at least looking at coloured
optics and some passive CWDM filters/combiners in that sort of
shorter-range deployment. No need to build a spaceship to travel across
town :-;.
