Ok..But I am a bit confused .I thought that each switch would have its own seperate 2 strands of fiber how would all the switches go down if they lost switch B or is this all working off the same 2 strands .

Just another note: There are only 3 location (A,B,C) A is the main location with a working network B is about 550 feet away from A and C is about 400 feet from B

I believe they are just installing 1 Computer at B & C

I would be just installing the fiber and the data company will be installing the fiber adapters
