Monitoring Optical Loss in Optical Network Systems: A New Methodology

Strategic Insights

— 1 min read

Researchers at Huawei Technologies Co., Ltd. have developed a novel method, device, and system for monitoring optical loss in optical network systems. This invention aims to provide a precise and rapid detection of reception sensitivity in optical modules, potentially improving the accuracy of link attenuation status between modules. The method involves adjusting the power of the received optical signal to obtain the reception sensitivity of the optical module and monitoring the power of the received signal, triggering an alarm when it exceeds the module's sensitivity threshold.

Key Takeaways:

  • The invention includes a monitoring method for optical network systems, which obtains reception sensitivity by adjusting the power of the received optical signal.
  • The method monitors the power of the received optical signal and triggers an alarm when it exceeds the module's sensitivity threshold.
  • The present invention also provides a monitoring device for the optical network system and an optical network system, ensuring the detection of reception sensitivity is rapid and accurate.
  • The methodology effectively avoids mistaking link attenuation status between optical modules, implying improved network performance.
  • The patent application was filed under Application No. PCT/CN2011/075092 on June 1, 2011, with a World Intellectual Property Organization (WIPO) publication number of WO/2011/144133.
