      Picked up the 10G BiDi 20KM modules to reuse existing fiber, and they did exactly what we needed. Saved us from pulling new fiber, which was a big win. Installed cleanly on our switches, matched pairs worked as expected, and the link has been stable since day one. Definitely a practical option when fiber count is limited.
