ABSTRACT:
The invention concerns an interface device for a fiberoptic communication network. The interface device comprises an electric circuit arrangement32,a first receiving section34for receiving a first transceiver module24and a second receiving section36for receiving a second transceiver module26.The interface device also comprises a switching unit54for switching said electric circuit arrangement between at least a first and a second state. Furthermore, the interface device includes a controller56arranged to automatically control the switching unit54in response to at least one control signal such that said first or second states are selected depending on whether at least one control signal is received indicating either that no transceiver module26is attached to said second receiving section36or that no optical signal above a certain signal level is received by a transceiver module26attached to said second receiving section36.The invention also concerns methods of using such an interface device.
