This would be my suggestion too but you dont need any WDM kit as you already are using different wavelengths, its possible to buy whats essentially a 3 way fibre connector and just connect both cards in and your fibre out. I believe these splitters are about $150.
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. ---Rob
