How easily? -Pete I remember a blurb in a recent issue of ECN about a "fiber tap", which bends the fiber just enough to let a small amount of light leak through and be picked up with (probably) a phototransistor. Sorry I can't be of more help, but I trashed the magazine as soon as I finished reading it. Spookfully yours, Gene
