Estive a pesquisar sobre as diferenças entre cabos de rede cat.6 e cat.6A e, pelo que consegui perceber, cat.6 é certificado até 250 Mhz e o cat.6A é certificado até 500Mhz. Ora o cabo que comprei tem apenas escrito cat.6 e não cat.6A, mas aparece a informação de 500Mhz. Será um cat.6A?
Category 6 (recognized cable type in ANSI/TIA-568-C) Category 6 cabling was officially
recognized with the publication of an addition to ANSI/TIA/EIA-568-B in June 2002. In addition
to more stringent performance requirements as compared to Category 5e, it extends the
usable bandwidth to 250MHz. Its intended use is for Gigabit Ethernet and other future highspeed
transmission rates. Successful application of Category 6 cabling requires closely matched
components in all parts of the transmission channel, that is, patch cords, connectors, and cable.
Category 6A or Augmented Category 6 (recognized cable type in ANSI/TIA-568-C)
Category 6A cabling was officially recognized with the publication of ANSI/TIA/EIA-
568-B.2-10 in February 2008. In addition to more stringent performance requirements as
compared to Category 6, it extends the usable bandwidth to 500MHz. Its intended use is for
10 Gigabit Ethernet. Like Category 6, successful application of Category 6A cabling requires
closely matched components in all parts of the transmission channel, that is, patch cords,
connectors, and cable. The cabling standards are discussed in more detail in Chapter 2.
Additional information on copper media can be found in Chapter 7, “Copper Cable Media,”
and Chapter 10, “Connectors.”
