Serial is also ever so slightly slower than gigabit fiber.
But more importantly -- fiber network cards have clearly physically separated transmitter and receiver ports. A transmitter port does not contain the hardware for receiving data, and the receiver port does not contain the hardware for transmitting.
A one-wire serial connection can (probably) be reversed by replacing the firmware of the controller chip. A one-way fiber connection as described in this article is physically incapable of transmitting data in the opposite direction.
