Huawei's Optical Network System Patent: Enhancing Communication Efficiency and User Satisfaction

Strategic Insights

— 1 min read

Huawei Technologies Co., Ltd. has developed a method, system, and device for data communication in an optical network system. The invention enables communication between a central office and multiple optical network units (ONUs) through a second optical line terminal (OLT) port after switching from a first OLT port. This innovation facilitates swift recovery of data communication between the switched OLT and ONU, reduces switching delay, and improves user satisfaction.

Key Takeaways:

  • The patent, filed under Application No. PCT/CN2011/074789 on May 27, 2011, describes a method to switch communication between the central office and ONUs to a second OLT port from a first OLT port.
  • The system sends a downlink frame or a deactivation message to at least one ONU via the second OLT port to facilitate ranging again.
  • The invention reduces switching delay and improves user satisfaction by swiftly recovering data communication between the switched OLT and ONU.
  • Huawei's patent addresses a problem in the optical network system where a popup message is not supported, and the network is not able to recover after being switched.
  • The patent has been published by the World Intellectual Property Organization with Publication No. WO/2011/144110 on November 24.

Statistics:

  • The patent was filed on May 27, 2011, under Application No. PCT/CN2011/074789.
  • The publication date of the patent is November 24.
  • The invention facilitates ranging again in optical network systems that do not support popup messages.
  • The switching delay has been reduced through the swift recovery of data communication between the switched OLT and ONU.
