Pinout pair ezijijekileyo

iindlela Modern kokufakelwa ukufikelela Internet iinketho ezininzi: ukusebenzisa intambo yafakwa, ifayibha optic kunye isibini ezijijekileyo. Makhe zihlale phezu iimpawu intambo ezijikeleze kunye pinout yenziwe njani na ababini, ephothiweyo, izinto ezifunekayo kunye noko imithetho kufuneka ilandelwe.

pair ezijijekileyo ibizwa ngcingo ukuba wayedityaniswe wambu usambathisa. Intambo ezijijekileyo ukuze kubandakanye izibini ezimbini okanye ezine, ephothiweyo of iingcingo, ibekwe esingxotyeni salo Heating. Iingcingo awafani uphawu ulwazi ombane ekhutshwe ngawo. iintlobo, ephothiweyo-isibini zinako ukuqatshelwa. Ba unshielded, eneli i screen bangaphandle, eneli iperi izikrini yangaphandle, ekhuselweyo ke wayivalela ezikhuselweyo. pair ezijijekileyo iye engxakini enye. Xa ukusebenza kwalo kukho umngcipheko iimbalelwano inkcazelo ethunyelwe yi intambo. Ukubaleka oko kuyimfuneko ukuze uphephe eaves. Kwelinye icala iintambo amsindise ayabiza kakhulu kwaye ke isetyenziswe enqabile.

Iintambo, nto leyo asetyenziswa kwisibini ephothiweyo, yahlulwe yaba ziindidi eziliqela. Eyokuqala intambo sefowuni yokudlulisela intetho. Ngesigaba USB 2 basenokugqithisela ulwazi yefrikhwensi ukuya megahertz mnye, Udidi 3 - elinesithandathu megahertz, isigaba 4 - ukuya mabini megahertz. Last asisetyenziswa kunqabile, ngenxa yokuba phantse akukho kwahluka intambo ndidi-3.

Oluhle kakhulu ngalo mzuzu ithathwa udidi intambo yesihlanu, eyenzelwe ukuba ukudluliselwa kolwazi ezitsho ukuya ku ikhulu megahertz. pair udidi ezijijekileyo 5 ayikho ngaphantsi kwe amathuba amabini anesixhenxe eemitha sobude nganye. Ngokuqhelekileyo, akukho ngamaceba eziliqela, amashumi amabini anesihlanu ngababini. Intambo ilungele loqhakamshelwano iikhompyutha kwi Internet kunye nokudalwa local network. Kukho iintambo 6 kunye neendidi 7, ibalwa ngokufanayo 200 600 megahertz. Udidi 6 ngentambo iyasebenza ukudibanisa kwiinethiwekhi Ethernet.

Xa uqhagamshela kuso womnatha wobulali iikhompyutha ubuncinane ezimbini iingxaki. Ukuze ukuzoyisa kwaye ukwenza udibaniso kakhulu kangangoko, kufuna amakhadi womnatha iikhompyutha kunye isibini ecikizekileyo, ephothiweyo, ubhekisela udidi yesihlanu, kwakunye izihlanganisi ezi RJ-45.

Ekubeni iintambo equlathe izibini ecikizekileyo, ephothiweyo, kunzima ukuba uthathe iplagi eludongeni, kufuneka crimp zabo, oluqhutywa ngokwemigangatho kunye nokusetyenziswa izixhobo ezikhethekileyo ukuba alichatshazelwa umgangatho zodluliselo lwedata. Ukuba intambo iye abaqhubi ezisibhozo, ebanjwe pinout ejijekileyo isibini Ethernet kunye nemigangatho Ethernet Gigabit. Ngenxa yokuba iintambo ekudidi 5 no-6 zibonisa kakuhle ngokwayo xa torsion kwaye ayeguqa, yokuba zisetyenziselwa ukuvelisa izintya patch adibanayo kunye zokuphuma kwimida ngempumelelo.

Lime embodiments ezimbini, okusetyenziselwa kokuxhuma iikhompyutha kwinethiwekhi okanye ukudibanisa i PC iintsimbi network (ngeentambo). Ngaphezu koko, lo womnatha yonke sobulali ukusebenzisa inguqulelo omnye kuphela, nto leyo iya kubanjwa, ephothiweyo-isibini pinout. Intambo kufuneka ilungiswe ukuze ifakwe isinxibelelanisi. Kubalulekile ukuqaphela ukuba i-RJ-45 Isidibanisi kufuneka crimped ngokulinganayo. Kukho iindidi ezimbini crimping, olusetyenziswa kwisibini ezijijekileyo. Eyokuqala (order phambili) unalo ulwalathiso "ifenishala Hub". Okwesibini - umnqamlezo, umnqamlezo-Linkova.

To connect ngqo ikhadi womnatha kweekhompyutha ezimbini, kufuneka yaze yangxenga ifuthe lomanyano intambo ukuze kwisibini (umzekelo, i-orenji kunye noluhlaza) umva. Ngoko ke pinout ebanjwe ezijijekileyo isibini USB, ngenxa apho enye izihlanganisi ukuba crimped kwi ngobuwena yokuqala, kwaye eyesibini - elinesibini. Intambo iya kubizwa ngokuba crossover. Kwakhona ebizwa nulhabnym.

Ngenxa yoko, inzuzo le ngababini ezijijekileyo ithathwa ukuba bakhululeke yofakelo kunye nendleko eziphantsi. abaqhubi balahleke abe eziphango uphawu okukhulu kakhulu eqhelekileyo ukudibanisa kwi Internet, ukuphucula umgangatho inkqubo esetyenziswayo pinout ejijekileyo cable isibini evumela ukuba ziziqhelanise iikhompawundi ngekhompyutha kunye peripherals.
