But, I'm not very current on the most economical methods for splicing and terminating the fiber, which ofcourse Iwould need to do on a "personal" sized budget. Any suggestions?This is somewhat off topic but have you tried any ethernet surge protectors? I use them here in the jungle with lots of lightning and it works good if your overall install is sound. Also you have to have your electrical ground tied to the conduit so it all stays at the same potential. But still fiber is the way to go. You could also go wireless with a pair of Ubiquiti Nanostation M2's Greg
Greg, Yes, that's the part about "5-port switch after the surge suppressors on the cable after building entry". Immediately after building entry I use HyperLink HGLN-CAT6 Lightning Protectors (See: http://www.l-com.com/item.aspx?id=22171 ) Then I connect to a "throwaway" 5-port switch (whatever was on sale last time I ran out). This switch is connected to it's own throwaway UPS, which is plugged into a separate power circuit from everything else. [[[ Note: If I could find cheap enough switches with an optical interface I would be switching to optical at this point! ]]] Then I connect from the throwaway switch to the real switch. But STILL I lose ports on the real switch from time to time. So converting the outside plant to fiber is a real goal. And the fiber prices are darn reasonable nowadays for 6 or 12 strands of 9/125: (Example http://www.showmecables.com/viewItem.asp?idProduct=10493 ) But outside plant fiber was never my thing, and I have no decent idea about how to get it spliced and terminated for reasonable costs, or really even what would be reasonable.
