Intelligence-defined optical tunnel network system and network system control method

An intelligence-defined optical tunnel network system, comprising:

• a plurality of optical switch interconnect sub-systems, comprising a first optical switch interconnect sub-system and a second optical switch interconnect sub-system,
• wherein the first optical switch interconnect sub-system transmits a corresponding first lateral transmission optical signal to the second optical switch interconnect sub-system through a first line and a corresponding second lateral transmission optical signal to the second optical switch interconnect sub-system through a second line, and the second optical switch interconnect sub-system comprises:
• a failover sub-module, configured to output one of the first lateral transmission optical signal and the second lateral transmission optical signal in response to a selective signal;
• and
• when signal intensity of the first lateral transmission optical signal is lower than a threshold value, a micro-control unit, configured to output the selective signal to the failover sub-module in order to control the failover sub-module to output the second lateral transmission optical signal.
