[AipuWaton] Ka Hoʻomaopopo ʻana i nā Uea ʻEwalu ma nā Uila Ethernet: Nā Hana a me nā Hana ʻoi loa.

640 (2)

Hiki ke huikau pinepine ka hoʻohui ʻana i nā uwea pūnaewele, ʻoiai ke hoʻāʻo nei e hoʻoholo i ka mea o nā uea keleawe ʻewalu i loko o kahi uwea Ethernet he mea nui ia no ka hōʻoia ʻana i ka hoʻoili pūnaewele maʻamau. No ka wehewehe ʻana i kēia, he mea nui e hoʻomaopopo i ka hana holoʻokoʻa o kēia mau uea: ua hoʻolālā ʻia lākou e hōʻemi i ka interference electromagnetic (EMI) ma o ka wili ʻana i nā pālua o nā uea i nā density kikoʻī. Hāʻawi kēia wili i nā hawewe electromagnetic i hana ʻia i ka wā o ka hoʻouna ʻana i nā hōʻailona uila e hoʻopau i kekahi i kekahi, me ka hoʻopau pono ʻana i ka hoʻopilikia ʻana. ʻO ka huaʻōlelo "twisted pair" e wehewehe pono i kēia hana.

Ka Evolution of Twisted Pairs

Ua hoʻohana mua ʻia nā pālua wili no ka hoʻouna ʻana i nā hōʻailona kelepona, akā ua alakaʻi ko lākou pono i kā lākou lawe ʻia ʻana i ka hoʻouna ʻana i nā hōʻailona kikohoʻe. I kēia manawa, ʻo nā ʻano i hoʻohana nui ʻia ʻo ia ka Māhele 5e (Cat 5e) a me ka Category 6 (Cat 6) mau pālua wili, hiki iā lāua ke hoʻokō i nā bandwidth a hiki i 1000 Mbps. Eia nō naʻe, ʻo kahi palena nui o nā kaula wili ʻia ko lākou mamao hoʻouna kiʻekiʻe loa, ʻaʻole i ʻoi aku ma mua o 100 mika.

He mea nui e hoʻomaopopo ʻaʻole pono ka hoʻopaʻanaʻau ʻana i ke kauoha T568A ma muli o kona emi ʻana. Inā makemake, hiki iā ʻoe ke hoʻokō i kēia maʻamau ma ka hoʻololi wale ʻana i nā uea 1 me 3 a me 2 me 6 e pili ana i ka hoʻonohonoho T568B.

Hoʻonohonoho Wiring no nā noi like ʻole

No nā noi maʻamau e hoʻohana ana i ka Māhele 5 a me ka Māhele 5e i hui ʻia, ʻehā mau uwea—no laila, ʻewalu mau uea kumu nui—e hoʻohana mau ʻia. No nā pūnaewele e hana ana ma lalo o 100 Mbps, ʻo ka hoʻonohonoho maʻamau e pili ana i ka hoʻohana ʻana i nā uea 1, 2, 3, a me 6. ʻO ka maʻamau uea maʻamau, ʻike ʻia ʻo T568B, hoʻonohonoho i kēia mau uea ma nā ʻaoʻao ʻelua penei:

1A
2B

T568B Kauoha Uea:

  • Pin 1: ʻalani-keʻokeʻo
  • Pin 2: ʻalani
  • Pin 3: ʻōmaʻomaʻo-keʻokeʻo
  • Pin 4: uliuli
  • Pin 5: uliuli-keʻokeʻo
  • Pin 6: ʻōmaʻomaʻo
  • Pin 7: ʻeleʻele-keʻokeʻo
  • Pin 8: ʻeleʻele

 

T568A Kauoha Uea:

Pin 1: ʻōmaʻomaʻo-keʻokeʻo
Pin 2: ʻōmaʻomaʻo
Pin 3: ʻalani-keʻokeʻo
Pin 4: uliuli
Pin 5: uliuli-keʻokeʻo
Pin 6: ʻalani
Pin 7: ʻeleʻele-keʻokeʻo

Pin 8: ʻeleʻele

Ma ka hapanui o nā pūnaewele Fast Ethernet, ʻehā wale nō o nā cores ʻewalu (1, 2, 3, a me 6) e hoʻokō i nā kuleana i ka hoʻouna ʻana a me ka loaʻa ʻana o ka ʻikepili. ʻO nā uea i koe (4, 5, 7, a me 8) he bidirectional a mālama ʻia no ka hoʻohana e hiki mai ana. Eia nō naʻe, ma nā pūnaewele ʻoi aku ka 100 Mbps, he hana maʻamau ka hoʻohana ʻana i nā uea ʻewalu. I kēia hihia, e like me ka Kāhua 6 a i ʻole nā ​​kaula kiʻekiʻe, me ka hoʻohana ʻana i kahi ʻāpana o nā cores hiki ke alakaʻi i ka paʻa o ka pūnaewele.

Ke kumu o kēlā me kēia Uea

No ka hoʻomaopopo maikaʻi ʻana i ke kumu e hoʻohana ʻia ai nā uea 1, 2, 3, a me 6, e nānā i nā kumu kikoʻī o kēlā me kēia kumu:

ʻO ke koʻikoʻi o ka mānoanoa o nā hui wili a me ka pale

I ka wehe ʻana i kahi uwea Ethernet, ʻike ʻoe i ka nui o ka wiliwili o nā hui uea ʻokoʻa. ʻOi aku ka ʻoi aku o ka wili ʻana o nā hui no ka hoʻoili ʻikepili—ʻo ka maʻamau o nā hui ʻalani a me ka ʻōmaʻomaʻo ma mua o nā mea i hoʻokaʻawale ʻia no ka hoʻokumu ʻana a me nā hana maʻamau ʻē aʻe, e like me nā pālua ʻeleʻele a me ka uliuli. No laila, ʻo ka hoʻopaʻa ʻana i ka maʻamau wiring T568B i ka wā e hana ai i nā kaula patch he mea koʻikoʻi no ka hana maikaʻi loa.

Manaʻo kuhihewa maʻamau

He mea maʻamau ka lohe ʻana i ka ʻōlelo a kekahi, "Makemake au e hoʻohana i kaʻu hoʻonohonoho ponoʻī i ka wā e hana ai i nā kaula; ʻae ʻia kēlā?" ʻOiai aia paha kekahi maʻalahi no ka hoʻohana pilikino ma ka home, ʻoi aku ka maikaʻi o ka hahai ʻana i nā kauoha wili i hoʻokumu ʻia i nā hiʻohiʻona ʻoihana a koʻikoʻi paha. ʻO ka haʻalele ʻana mai kēia mau kūlana hiki ke hōʻemi i ka maikaʻi o nā kaula wili, e alakaʻi ana i ka nalowale o ka lawe ʻana i ka ʻikepili nui a me ka hoʻemi ʻana i ka mamao o ka lawe ʻana.

Ka hopena

I ka hōʻuluʻulu manaʻo, inā hoʻoholo ʻoe e hoʻonohonoho i nā uea ma muli o ka makemake pilikino, e hoʻopaʻa pono i ka hoʻohui ʻana i nā uea 1 a me 3 i hoʻokahi pālua wili, a me nā uea 2 a me 6 i hui pū ʻia i kahi hui wili ʻē aʻe. ʻO ka hahai ʻana i kēia mau alakaʻi e hōʻoia i ka hana pono a me ka hilinaʻi o kāu pūnaewele.
