Kubatanidza tambo dzenetiweki kunowanzo kuvhiringa, kunyanya kana uchiedza kuona kuti ndeipi waya sere dzemhangura mukati meEthernet tambo yakakosha pakuona kuti yakajairika network network. Kuti ujekese izvi, zvakakosha kuti unzwisise kushanda kwese kwewaya idzi: dzakagadzirirwa kudzikisa electromagnetic interference (EMI) nekumonyanisa mawaya pamwe chete pane chaiwo densities. Uku kumonyoroka kunobvumira mafungu emagetsi anogadzirwa panguva yekufambiswa kwemasaini emagetsi kuti adzima mumwe nemumwe kunze, achibvisa zvinogoneka kukanganisa. Izwi rekuti "twisted pair" rinonyatsotsanangura kuvakwa uku.

The Evolution of Twisted Pairs

Mapeya akamonyoroka aimboshandiswa pakufambisa masaini enhare, asi kushanda kwawo kwakakonzera kutorwa kwavo zvishoma nezvishoma mukufambiswa kwemasaini edhijitari zvakare. Parizvino, mhando dzinoshandiswa zvakanyanya iCategory 5e (Cat 5e) uye Category 6 (Katsi 6) yakamonyoroka mapeya, ose anokwanisa kuwana bandwidths anosvika 1000 Mbps. Nekudaro, chinodzikisira chakakosha chetambo dzakamonyoroka tambo irefu yavo yekutapurirana kureba, iyo isinga pfuure 100 metres.

Izvo zvakakosha kuti uzive kuti kubata nemusoro iyo T568A odha hazvidiwe nekudzikira kwayo. Kana zvichidikanwa, unogona kuwana chiyero ichi nekungochinjanisa waya 1 ine 3 uye 2 ine 6 zvichienderana neT568B kumisikidzwa.

Wiring Configuration yeMashandisirwo Akasiyana

Pamashandisirwo akajairwa uchishandisa Chikamu 5 uye Chikamu 5e akamonyoroka mapeya, mapeya mana ewaya-saka, masere ese epakati waya-anowanzo shandiswa. Kune network inoshanda pasi pe 100 Mbps, iyo yakajairwa gadziriso inosanganisira kushandisa waya 1, 2, 3, uye 6. Iyo yakajairwa wiring standard, inozivikanwa seT568B, inoronga waya idzi kumagumo ese nenzira inotevera:

T568B Wiring Order:

  • Pini 1: orenji-chena
  • Pini 2: orenji
  • Pini 3: girini-chena
  • Pini 4: bhuruu
  • Pin 5: bhuruu-chena
  • Pini 6: girini
  • Pini 7: brown-white
  • Pini 8: brown

 

T568A Wiring Order:

Pini 1: girini-chena
Pini 2: girini

Pini 6: orenji
Pin 7: brown-white

Pini 8: brown

Muzhinji Fast Ethernet network, mana chete pamasere cores (1, 2, 3, uye 6) anozadzisa mabasa ekufambisa nekugamuchira data. Waya dzakasara (4, 5, 7, uye 8) dzine mativi maviri uye dzinowanzochengeterwa kushandiswa mune ramangwana. Nekudaro, mumatiweki anopfuura 100 Mbps, itsika tsika kushandisa ese masere waya. Muchiitiko ichi, senge neChikamu 6 kana tambo dzepamusoro, kushandisa chete subset yemacores kunogona kutungamira kune kukanganisa network kugadzikana.

Chinangwa cheWaya imwe neimwe

Kuti unzwisise zviri nani kuti sei waya 1, 2, 3, uye 6 dzichishandiswa, ngatitarisei zvinangwa zvepakati yega yega:

Kukosha kwe Twisted Pair Density uye Shielding

Pakubvisa tambo yeEthernet, iwe unozoona kumonyoroka kwehuviri hwewaya hunosiyana zvakanyanya. Iwo maviri maviri ane basa rekufambiswa kwedata-kazhinji maorenji negirini peya-akamonyaniswa zvakanyanya kupfuura ayo akagoverwa pasi uye mamwe mabasa akajairika, senge brown neblue peya. Naizvozvo, kuomerera kune T568B wiring standard kana kugadzira chigamba tambo kwakakosha pakuita kwakaringana.

Mafungiro Akajairika

Hazvishamisi kunzwa vanhu vachiti, "Ndinoda kushandisa gadziriro yangu pakugadzira tambo; zvinotenderwa here?" Nepo panogona kunge paine kuchinjika kwekushandisa wega kumba, zvinokurudzirwa kuteedzera yakamisikidzwa wiring maodha mumamiriro ehunyanzvi kana akakosha. Kutsauka kubva pazviyero izvi kunogona kukanganisa kushanda kwetambo dzakamonyoroka, zvichitungamira mukurasikirwa kukuru kwekutapurirana data uye kudzikiswa kwechinhambwe chekutapurirana.

Mhedziso

Muchidimbu, kana ukasarudza kuronga waya zvichienderana nezvaunoda iwe, ita shuwa kuisa waya 1 ne3 pamwe chete mune imwe yakamonyoroka peya, uye waya 2 ne6 pamwe chete mune imwe yakamonyoroka peya. Kutevera nhungamiro idzi kunovimbisa kuti network yako inoshanda nemazvo uye nekuvimbika.
