Abstract

The embodiments of the invention relate to an input module (IM-1, IM-2, IM-3, ..., IM-N) for a switching system (RSS). The input module (IM-1, IM-2, IM-3, ..., IM-N) contains at least one input port configured to receive at least one input data stream. The input module (IM-1, IM-2, IM-3, ..., IM-N) further contains a processing unit configured to determine, whether a data rate of the at least one input data stream to be transmitted from the input module (IM-1, IM-2, IM-3, ..., IM-N) to one of at least twooutput modules (OM-1, OM-2, OM-3, ..., OM-N) of the switching system (RSS) via an optical transmission path by a fixed wavelength optical signal having a fixed wavelength exceeds a maximum transmission capacity of the optical transmission path. The input module (IM-1, IM-2, IM-3, ..., IM-N) even further contains a packet switching module configured to switch at least first data packets of the at least one input data stream to the optical transmission path and to switch at least second data packets of the at least one input data stream to at least one further optical transmission path from the input module (IM-1, IM-2, IM-3, ..., IM-N) to the one of the at least two output modules (OM-1, OM-2, OM-3, ..., OM-N), when the data rate of the at least one input data stream exceeds the maximum transmission capacity. The input module (IM-1, IM-2, IM-3, ..., IM-N) even further contains at least one fixed wavelength optical transmitter module configured to transmit via the optical transmission path the fixed wavelength optical signal that carryies the at least first data packets and even further contains at least one tunable wavelength optical transmitter module reconfigurable to transmit via the at least one further optical transmission path a tunable wavelength optical signal having a tunable wavelength and carrying the at least second data packets. The embodiments further relate to a central control unit (CCU) for a switching system (RSS) and to a switching system (RSS).
