An intelligence-defined optical tunnel network system includes pods. Each pod includes optical add-drop sub-systems. Each optical add-drop sub-system includes a first transmission module and a second transmission module. The first transmission modules of the optical add-drop sub-systems are connected to each other for forming a first transmission ring. The second transmission modules of the optical add-drop sub-systems are connected to each other for forming a second transmission ring. Each first transmission module includes a multiplexer and an optical signal amplifier. The multiplexer is connected to a Top-of-Rack switch. The multiplexer is configured to receive, through input ports, upstream optical signals from the Top-of-Rack switch, and combine the upstream optical signals into a composite optical signal. The upstream optical signals have wavelengths respectively. The optical signal amplifier, coupled to the multiplexer, is configured to amplify the composite optical signal and output an amplified composite optical signal.

Intelligence-defined optical tunnel network system

An intelligence-defined optical tunnel network system includes a plurality of pods. Any one of the pods includes a plurality of optical add-drop sub-systems (OADS), which are configured to perform data transmission, respectively, through a plurality of Top-of-Rack (ToR) switches between a corresponding plurality of servers. Any one of the OADSs includes a first transmission module and a second transmission module. The first transmission module is configured to perform data transmission at a first frequency band, and the first transmission module of any one of the OADSs connected to the first transmission module of the adjacent OADSs to form a first transmission ring. The second transmission module is configured to perform data transmission at a second frequency band differed to the first frequency band, and the second transmission module of any one of the OADSs connected to the second transmission module of the adjacent OADSs to form a second transmission ring.

An intelligence-defind optical tunnel network system includes a first tier network and a second tier network. The first tier network includes multiple pods, any one of which includes multiple Optical Add-Drop Sub-systems (OADS) configured to transmit data between corresponding servers through ToR switches. The second tier network includes multiple Optical Switch Interconnect Sub-systems (OSIS). Any two of the OSISs transmit a corresponding lateral optical signal via a first line correspondingly. Any two adjacent OSISs are coupled to the OADSs in the same pod of the first tier via multiple optical paths respectively.

An intelligence-defined optical tunnel network system includes multiple Optical Switch Interconnect Sub-systems (OSIS), in which a first OSIS is configured to transmit a first lateral transmission optical signal via a first line to a second OSIS, and transmit a second lateral transmission optical signal via a second line to the second OSIS. The second OSIS includes a failover sub-module and a micro-control unit. The failover sub-module is configured to output one of the first and the second lateral transmission optical signal based on a selective signal. The micro-control unit is configured to output the selective signal to the failover sub-module to control the failover sub-module output the second lateral transmission optical signal if a signal intensity of the first lateral transmission optical signal is lower than a threshold value.

An intelligence-defined optical tunnel network system includes a first pod and a controller. The first pod includes multiple Optical Add-Drop Sub-systems (OADS) configured to transmit data between corresponding servers through ToR switches. First transmission modules of the OADSs are connected to each other in ring to form the first transmission ring. Second transmission modules of the OADSs are connected to each other in ring to form the second transmission ring. The controller is configured to set the ToR switches in order to build the optical tunnel from a first OADS to a second OADS on the second transmission ring by the second transmission modules if a disconnection occurs to the optical tunnel from the first OADS to the second OADS on the first transmission ring.

An intelligence-defined optical tunnel network system includes multiple Optical Switch Interconnect Sub-systems (OSIS). Any one of the OSIS includes a receiving sub-module, an output sub-module, an interconnection fabric module and an optical switching sub-module. The receiving module is configured to receive multiple first and third upstream optical signals from first and second Optical Add-Drop Sub-systems (OADS) corresponding to the first and the second pods. The output sub-module is configured to output multiple second and fourth downstream optical signals to the first and second OADS. The interconnect circuit sub-module is configured to connect adjacent two of the OSISs and any two of the OSISs transmit a corresponding lateral transmission optical signal via a first line correspondingly. The optical switching sub-module is configured to transmit optical signals between the receiving sub-module, the output sub-module, and the interconnection fabric module.
