The device would have to support the SFP and, since the transmit and receive are on different wavelengths, UDLD could be coded to respond to it in the same way it responds to transmit and receive on different interface ports. However, I don't think Cisco supports these optics in their switching platform. Please someone correct me if I'm wrong! I've seen these devices as transceivers that feed back to the device over UTP.
