Indlela crimp izihlangu singakugqwethi Ethernet 100 Mb

Kakade nokufika kweekhompyutha yokuqala beza imfuneko ngendlela elula ngok unxibelelwano lwedijithali phakathi kwabo. Egqojozwe iimakhishithi, Imagnethi iiteyiphu kunye Disks (kuqala bhetyebhetye uze ngqwabalala), amajelo ezamehlo nangona ngokuyinxenye kusonjululwa le ngxaki, kodwa ukusetyenziswa kwazo ethile omnye - kuyimfuneko ukuba ngandlel 'ithile ukuze baphumeze yenethiwekhi yokukhulula idata kwi computer ekujoliswe kulo, ngoko " lula "waba phantsi kweemeko kakhulu.

Akumangalisi ke ukuba le yee- kwabakho ithuba lokudlulisela ulwazi phakathi izixhobo digital ngokusebenzisa lombutho unodibaniso phakathi kwabo (Ethernet). Xa ikhompyutha nganye simisela iadaptha ezizodwa (uNic), edityaniswe intambo yafakwa ixhulumane. Oku ukuba ukuze adlulisele idata ngqo, ngokungqinelana ne-Ethernet standard 10BASE2 (nezinye ntlobo zibizwa ngaphantsi kakuhle kwaye kufumaneka ngokubanzi). Noko ke, ukuwalungisa ukuba amanzi ka intambo yaba ohms-50, nto leyo eyenza kube nzima ukuphelisa umonakalo kunokwenzeka.

Nokufika ngakumbi mihla, ugcine Ethernet, ukuxhasa transfer ikhawulezisa ku megabits 100, intambo yafakwa indawo kunye ababini, ephothiweyo. Ukongeza ekunciphiseni iindleko ikhefu kuyo nayiphi na umphakathi ukuba bajije ngokulula kwaye kwakhona ingxenye. Yintoni ipere ezijijekileyo? Oku ngababini ezininzi ababhexeshi ekwanti ejijekileyo ngababini iqokelelwe kwiqokobhe enye. Ngumqhubi ukuba babephila xa iyonke, kwaye ikwabandakanya iinwele entle zezobhedu. I ukhetho lokuqala - buti idla isetyenziselwa ukwakhiwa kweendonga ukuya zokuphuma nokwabiwa. Inyathelo plexus isibini ngasinye eyahlukileyo, oko kunciphisa crosstalk. Iingcingo azakubalulwa umbala ubushushu, ngoko ke "Ayanda" ayikho imfuneko.

Ngamanye amaxesha ke nanku umbuzo, yintoni na intambo isiziba. Yeyona intambo yokudibanisa kunye izihlanganisi emancamini. Ngokuqhelekileyo, ubude kuphela m 5, nkqu njengomgangatho ofisi TSB-75 lelona isithintelo isusiwe. Ukuba ufuna ukudibanisa iikhompyutha ezimbini omnye komnye, intambo patch zingathengwa kuyo nayiphi na ivenkile zobugcisa computer.

Hi ndlela leyi, njengoko umthetho, olu hlobo cable "ejijekileyo isibini". kwaye umthengi akukho mfuneko ukuba ndicinge ukuba crimp njani isibini ephothiweyo, kuba izihlanganisi sele idityaniswe ngendlela ethile (ngokuqhelekileyo PC-to-PC, cross-ukuqhagamshela okanye "crossover"). Qaphela ukuba izixhobo ezininzi mihla ibhaqe ngokuzenzekelayo uhlobo lonxibelelwano kwaye lungisa kuyo. Kodwa, ngamanye amaxesha kufuneka ngokwakho ukuqonda ukuba crimp njani isibini ezijijekileyo. Ngokomzekelo, xa Ukusungula ukuhlangana LAN.

Kule meko kuyimfuneko ukufunda kwiiforam ezifanelekileyo nezinto ezizodwa. Ngendlela, ukuba compress indlela isibini, ephothiweyo, akukho nto inzima - nje care encinane kunye nokuchaneka.

Uyakwazi uthenge ezizodwa iplayasi crimping, ixabiso iyafumaneka kakhulu. Nangona, kunye nobuchule ngenxa, nonke nina ungenza kwenza iinzipho.

Ngoko ke, indlela crimp isibini ezijijekileyo? Ifuna intambo ngokwalo (eziviwayo didi ezijijekileyo 5 100 Mbit umda umgama - malunga 130 m) kunye ezimbini RJ-45 isinxibelelanisi. Sika usiko intambo, sizenze nokuphungula off umonakalo. Ukususa umaleko ongaphandle usambathisa. Ubude kwale nxalenye kuxhomekeke kuhlobo isinxibelelanisi: esi sokugqibela sona kufuneka ulungise isigubungelo inxalenye kwaye akuxhome kwezinye abaqhubi. Couples ukuqhekeka nokungqinelanisa (ukuba athethe 1 cm). Ngokuhambelana scheme (bona ngezantsi) ufake iingcingo kungena isinxibelelanisi. Ngenxa ntwala ukuqhagamshela iingcingo kubo.

Kukho iindlela ezimbini ukuya crimp - T568A (inkampani Siemon), kunye T568B (AT & T). Uninzi wayedla uhlobo yesibini. Imiyalezo yokuqala kudluliselwa phezu ekhoyo "-green emhlophe" kunye "white--orenji", naorenji iingcingo eluhlaza. Eyesibini i iperi "-orange emhlophe" kunye "green-emhlophe" namhlophe kunye eluhlaza.

To connect izixhobo ezahlukeneyo (hub-PC) kusetyenziswa indlela efanayo le khompawundi ezivela macala omabini. Ukuba ufuna ukudibanisa iikhompyutha ezimbini okanye hub ezimbini, ukuba isandla omnye intambo Yaphathana yi T568A, yaye kwelinye - phezu T568V. imizobo kweentambo Visual nga lula afumaneka kwimithombo efanelekileyo kwi web.

Council for the "ivila": ukudala uthungelwano olula iiPC ezimbini unako ukuthenga patch intambo esele zenziwe kwaye cable "isibini ezijijekileyo" sobude ofunekayo. Sika intambo patch phakathi, ukucoca iziphelo izinikezeli kwayo kwaye ubukhulu becala cable twist (solder) ezingundoqo ngokungqinelana lwemibala. Ngci. Le isisombululo isebenza kakuhle imigama efikelela kwi-140 m.
