A method of communicating data between a network device and a data network which are connected to each other by means of an optical fibre data link is disclosed. The method comprises the steps of : within the device, monitoring the connection to detect data communication at a first standard, and either: a) if data communication is detected at the first standard, establishing data communication between the network device and the network using the first standard; or b) if no data communication is detected at the first standard, monitoring the connection in the device to detect data communication at a second standard and if data communication is detected at the second standard, establishing data communication between the network device and the network using the second standard. A communication device using such a method is also disclosed. |
