  • What are the measurement methods for 10 Gigabit multimode fiber optic cables

    What are the measurement methods for 10 Gigabit multimode fiber optic cables

    As fiber deployments become commonplace, network owners and technicians are paying more attention to the two crucial devices for testing fiber optical cables: the Optical Loss Test Set (OLTS) and the Optical Time Domain Reflectometer (OTDR). An OLTS provides the most accurate insertion loss. Testing fiber optic components and cable plants requires making several measurements with the most common measurement parameters listed in the Table below. The method shown is on the FOA "1 Page Standard" FOA1 which you may print or download and insert in your documentation. EF is a method of characterizing the launch conditions of a multimode light source such as an LED or laser.


  • Is relay protection debugging difficult

    Is relay protection debugging difficult

    Explore why relay protection testing is becoming more complex with IEC 61850 systems, and discover practical steps to streamline your protection workflows. If you've been in protection testing for a while, you'll know the job has changed – not always for the better. Where once you could trust. In the actual operation management process, it is required to form a different debugging and management scheme with the corresponding relay protection device, and regularly check its operation status, so as to achieve the concept of fault detection and timely treatment.
