PURPOSE: A media converter, a control method therefor, and a system and a method for detecting a failure using the same are provided to perform a response test to be activated from a cable side and to easily detect the occurrence of the failure. CONSTITUTION: A pair of physical-layer interfaces(101,102) connected to transmission media with different types are connected through a memory(103) for temporarily storing data to be transferred between the physical-layer interfaces(101,102). A media converter(10) determines whether a received block of data stored in the memory(103) includes trigger data uniquely assigned to the media converter(10) in a source address field of the received block of data. Only when the received block of data stored in the memory(103) includes the trigger data, a response block of data corresponding to the received block of data is sent back to a source that has transmitted the received block of data.
