1000base-lx cable length

furby

Hi,

I bought the syngress n10-003 book and i was reading about 1000base-lx and the book says that the maximum cable length is 10 km.

but i also bought the network+ book from mc graw hill and that book says that the maximum cable length is 3 km.

I read in the network+ 2005 in depth and that book says that the maximum cable length is 5000 meters.

And the sybex book says that the maximum cable length is 2km.

Does anybody know what the correct length is?

ahhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhh



Thanks in advance.
