Don't forget to add in the appropriate losses into your link budget if
you're going more than a couple hundred feet (not the case with the
original post, but worth noting).  Theoretical losses for a 50/50 beam
splitter would be about 3dB, with about 3dB for the recombiner as
well...  but if memory serves the actual real-world additional losses
when one adds splitters to both ends is about 10dB, which would
suggest an additional 2dB of random inefficiency per splitter (quite
believeable).

Others on the list can attest to success with 90/10 beamsplitters
running full-duplex on a single fiber, at least with 100baseFX.
Recommend www.netoptics.com as a good, responsive source for
splitters/taps.
