Podrobnejsi info primo od zdroje (TIA vydala az po uzaverce tohoto clanku):
The Telecommunications Industry Association (TIA) announced today (24/6) that
the category 6 standard for telecommunications cabling has been approved for publication as
TIA/EIA-568-B.2-1. This addendum is part of the TIA/EIA-568-B series of commercial
building cabling standards, which are the most successful standards published by TIA. The
new category 6 standard specifies requirements for 100-ohm balanced twisted-pair cables,
connecting hardware, patch cords, channels and permanent links, and provides test
procedures for laboratory and field performance verification over the frequency range of 1
to 250 MHz. Because category 6 supports positive power sum attenuation to crosstalk
(PSACR) margins up to 200 MHz, this new cabling system offers double the bandwidth of
category 5e cabling and vastly improved signal-to-noise margins. The category 6 standard
also includes cable and connecting hardware balance recommendations for improved
electromagnetic compatibility!
performance.
Category 6 cabling recognizes advances in cabling technology and is designed to be
backward compatible with categories 3, 5 and 5e. This ensures that any applications that
operate on lower category cabling will be fully supported by category 6 cabling. When
different category components are mixed with category 6 components, the resultant cabling
will satisfy the category transmission requirements of the lower performing component. To
ensure generic cabling system performance, category 6 component requirements are
specified to be interoperable when products from different manufacturers are mated.
According to TIA TR-42 Committee Chair Bob Jensen, the publication of the category 6
standard represents a milestone in the history of commercial building cabling specification.
"Category 6 facilitates data throughput previously unachievable over balanced twisted-pair
cabling. TIA and the ATM Forum have already published gigabit applications standards to
operate over category 6 cabling. We anticipate applications groups to begin development of
protocols supporting even higher throughput over category 6 cabling."
A nebylo by bývalo lepší chvilku počkat a napsat doopravdy něco o kabeláži kategorie 6? Takhle je článek čtivý asi jako telefonní seznam a informačně se blíží nule. Docela by mne zajímalo, jestli někdo ty orgie zkratek a názvů přečetl až do konce a jestli mu to něco přineslo. Já osobně jsem se doufal dozvědět něco o Cat 6 a k tomu rozhodně nedošlo. Přiznám se, že jsem čtení vzdal po pár odstavcích a pak už jen "skenoval".
