Neil, Unless you need the speed or connectivity, I would prefer messing with copper. Just too many strange incompatibilities with optical SFPs and various vendors equipment when you go optical. Things that should work, don’t, and visa versa. Wasn’t that terrible in our lab at work, because we had loads of different SFPs, cables and switches to change out to try to get things working, but at home, that sort of experimenting will most likely cost you money. At work, it mostly cost us time, and it was just part of the cost of doing business. After a while, it became a pretty routine thing for us to swap SFPs or switch ports when optical links didn’t come up when connecting new gear. When Service Providers do deployments of new equipment, they trial every component in the system before rollout for a reason. Just my two cents… Mike Willegal
+1 CDL is running a CISCO 4900M as the core, with OM3 10GB links to the edge switches that are physically in building 9059. The links to the other buildings will be single mode 1310nm fiber due to length. And to avoid mix and match, it's all CISCO optics and modules....

In the business settings you and I are used to (I was a network SE) this makes perfect sense. Reduces the questions during diagnostics. Saving a few dollars when cost of loss during diagnostics is penny wise, pound foolish. For my home I'm don't mind some experimenting. But I do need to keep my CFO happy. ;-) -- Linux Home Automation Neil Cherry ncherry@linuxha.com http://www.linuxha.com/ Main site http://linuxha.blogspot.com/ My HA Blog Author of: Linux Smart Homes For Dummies
There’s enough corporate leftover and donations to avoid mix and match. Hopefully it stays that way!! Sent from my iPhone

Cisco qualified and rebranded 3rd party SFPs. If I remember right, Avago was one of the primary suppliers. Things probably have changed since I was involved. Mike Willegal Sent from my iPhone
