Is it possible to use half duplex on a trunk link?
Of course your going to say why would anyone want to do this, but imagine for a minute you had one bad fiber and no redundancy. Could you get the link up by using the one fiber link with half duplex? I know your network throughput would suck, but just to get the link up until you get someone out to replace/repair the fiber.
Still searching for the corner in a round room.
