This part of ISO\/IEC 11801, which is a Technical Report,<\/p>\n

    \n
  1. \n

    provides guidance on how to select and assess installed channels which conform to ISO\/IEC 11801\u20111, and clarify if they also support ISO\/IEC\/IEEE 8802\u20113:2017\/AMD3 for 25GBASE-T;<\/p>\n<\/li>\n

  2. \n

    specifies the methods to assess whether installed channels constructed with Category 7A<\/sub>, 7, or 6A<\/sub> components meet the 25GBASE-T requirements;<\/p>\n<\/li>\n

  3. \n

    provides guidance to identify which channels are likely to meet the 25GBASE-T requirements to avoid unnecessary testing;<\/p>\n<\/li>\n

  4. \n

    provides mitigation techniques to improve the performance of installed channels to meet the 25GBASE-T requirements;<\/p>\n<\/li>\n

  5. \n

    provides cabling recommendations for new installations.<\/p>\n<\/li>\n<\/ol>\n
