Mandiqale ngokukhumbula incoko yangaphambili apho ndachaza khona ukuba yintoni intambo ye-fiber optic. Ngoku ufuna uthelekiso, ngoko ke kufuneka ndibonise umahluko phakathi kwezi zimbini.

Intambo yeFiber Optic ngokuchaseneyo Intambo yeCopper

Okokuqala, kufuneka ndiqwalasele iinkalo eziphambili ekufuneka ndizithelekise. Mhlawumbi i-transmission medium, isantya, umgama, i-bandwidth, ukuphazamiseka, ukhuseleko, iindleko, ukuqina, kunye nezicelo. Mandiqinisekise ukuba ndizigubungela zonke ezi ngongoma.

Isixhobo sokudlulisa: Ifayibha isebenzisa ukukhanya, ithusi isebenzisa imiqondiso yombane. Ngumahluko ophambili lowo. Isantya kunye ne-bandwidth: Ifayibha ikhawuleza kakhulu xa i-bandwidth iphezulu. Umgama: Ifayibha inokudlulisa kumgama omde ngaphandle kokulahleka kwesignali. Ukuphazamiseka: Ifayibha ayichaphazeleki yi-EMI, eyile copper. Ukhuseleko: Ifayibha kunzima ukuyicofa, ngoko ke ikhuselekile ngakumbi. Ixabiso: I-Copper ixabisa kancinci ngaphambili kodwa ifayibha ineendleko eziphantsi zexesha elide. Ukuqina: Ifayibha ibuthathaka ngakumbi ngokwasemzimbeni kodwa ingcono kwiindawo ezinzima. Izicelo: Apho isetyenziswa khona nganye.

Linda, kufuneka ndijonge ukuba kukho enye into. Owu, mhlawumbi i-latency. I-Fiber ine-latency ephantsi, ebalulekileyo kwizicelo zexesha langempela. Kwakhona, ukuhanjiswa kwamandla: I-Copper inokuthwala amandla (njenge-PoE), i-fiber ayinakho. Ngoko ke izixhobo ezisebenzisa i-fiber zifuna amandla ahlukeneyo.

Ndifuna ukuyila oku ngokucacileyo. Mhlawumbi itheyibhile inganceda, kodwa ungafuna ingcaciso emfutshane. Makhe ndichaze udidi ngalunye ngamanqaku eebhulethi, ndiwathelekise ecaleni kwelinye.

Iimeko ezinokubakho zomsebenzisi: Basenokuba ngumfundi ophanda iprojekthi, ingcali ye-IT egqiba ngeziseko zophuhliso, okanye umntu onomdla kwi-intanethi yakhe yasekhaya. Impendulo kufuneka ifumaneke kodwa ibe nenkcazelo eyaneleyo kubafundi bezobugcisa.

Qiniseka ukuba ukhankanya iimeko ezithile zokusetyenziswa, ezifana nefayibha kwiintambo ezingaphantsi kolwandle kunye ne-telecom yomgama omde, i-copper kwi-Ethernet run emfutshane. Kwakhona, thetha ngeendlela eziza kwenzeka kwixesha elizayo, njengefayibha eba yinto eqhelekileyo njengoko iindleko zincipha.

Ndifanele ndikhankanye nokuba ndikhethe nini nganye. Umzekelo, ukuba uhlahlo lwabiwo-mali luyimida kwaye umgama umfutshane, i-copper inokuba ngcono. Ukuba ufuna isantya esiphezulu kunye nokhuseleko, i-fiber yindlela efanelekileyo.

Jonga naziphi na iingcamango eziphosakeleyo eziqhelekileyo. Umzekelo, abanye banokucinga ukuba ifayibha isoloko ibiza kakhulu, kodwa ngokuhamba kwexesha, iindleko zokulungisa ziphantsi. Kwakhona, cacisa ukuba nangona ifayibha ibuthathaka, ingcono kwiindawo ezinokuphazamiseka okuninzi.

Jonga kabini iinkcukacha zobugcisa: ubungakanani obuphambili, isantya sokudlulisa, umgama ophezulu. Umzekelo, umgama wefayibha yemowudi enye vs umgama wefayibha yemowudi ezininzi. Imida yeCopper nge-crosstalk kunye ne-EMI.

Kulungile, yakha impendulo ngezihloko ezicacileyo kwicala ngalinye lokuthelekisa, sebenzisa amanqaku okanye uluhlu oluneenombolo ukuze ucace, kwaye ugqibezele ngesishwankathelo kunye neengcebiso ezisekelwe kwiimeko zokusetyenziswa. Qinisekisa ukuba kulula ukuyifunda kwaye uphendula zombini izinto zobugcisa kunye nezisebenzayo.
