	While I haven't done it on GigE (yet) netoptics optical splitters
work fine for ATM and should work fine for GigE. I use the %80/%20 version
but %50/%50 is available (depending on the length of run and power budget of
what you are tapping in to). You do need an IDS capable of doing FDX for this.

> We are trying to fiugure out a way to gather IDS data via gigabit LX taps, but it seems that there are a number of obticles. Apparently, you will loose lower level errors if you use port-mirroring on a switch, not to mention the amount of data that is lost due to light splitting. Does any one have any suggestions or information as to how this might be done?
