Ifayibha-optic cable - uhlobo olwahlukileyo media iingcingo ezihamab phantsi

Ukuza kuthi ga ngoku, ifayibha optic cable uhlobo olwahlukileyo kwindawo cable le. Njengoko element esisiseko kuphuma iglasi, ukuvumela ukudlulisa ulwazi phezu imigama emide ngaphandle nelahleko ebonakalayo ngesantya. Transmission kulo mzekelo ikhutshwa phandle kungekhona yimitha yombane, yaye ngoku ubume ekukhanyeni, enceda ukunika okukwazi ingxolo ephezulu kunye nokhuseleko ukwaziswa. Noko ke, ukufakwa fibre optic cable kudala ubunzima obuthile kuba ifuna phakathi kokufakwa izihlanganisi micron nokuchaneka. Ukususela oku kuya kuxhomekeka ngakumbi inkqubo eziphango.

Ngokuqhelekileyo, ngokubekwa fibre-optic cable kwenziwa ngesandla okanye ukusetyenziswa winches ezizodwa. Kwinkqubo umsebenzi kufuneka ithathele ingqalelo emininzi ezinokuphembelela umphumo. Xa ngokubekwa izixhobo ezikhethekileyo kufuneka isetyenziswe ukunceda ukunciphisa inani ukukhuhlana kwaye uphephe umonakalo kwiindawo ukuvumela. Ukuqinisa lwenziwa winches, nokumisela zokutsalwa kwimithwalo. Ekupheleni amaqula intambo ushiye imajini ukuba iibhokisi intambo.

Nayiphi Intambo fibre optic kunokuba indlela eyodwa okanye multimode. Kwimeko yokuqala, zonke imitha boyise indlela enye ukufikelela ngumamkeli ngexesha elinye. Ngokuba lo hlobo transceiver laser ofanelekileyo ukukhanya kunye kwamaza oyifunayo. Kufuneka kuchazwe ukuba iindleko kakhulu eziphakamileyo, kodwa kwixesha elizayo elikufutshane, olu khetho kucingwa ukuba ethembisayo.

Njengokuba oothixo multimode, kufuneka ukwahluka omkhulu, ngenxa yokuba apho kukho ubugqwetha kwi ulwamkelo. udumo lwabo kubangelwa ikakhulu ukuya cheapness isalamane. Ulibaziseko umqondiso networks ezinjalo ziya malunga kunxibelelana uthungelwano intambo yombane.

Nangona fibre optic cable kwaye damping buthathaka kakhulu, ine- nkcithakalo semvelo chromatic, nto leyo a ukudluliselwa ukukhanya eyahlukileyo bengaphaya kweglasi. Ngaloo ndlela, uphawu ukukhanya ukuba ibolile zibe kumacandelo umbala ngamnye (isiphumo rainbow). On icandelo elincinane uyakwazi ukufumana ukungena bit elandelayo, nto leyo ekugqibeleni kukhokelela ukulahleka data. Nangona kunjalo, oku akusebenzi ziintambo olunye-imowudi, apho ukukhanya wadlulisela na ukuba zezantoni efanayo. Xa zisetyenziswa lungenzeki nomphumo usasazeko chromatic.

Enyanisweni, intambo fibre optic na isakhiwo efanayo kumntwana wakowenu yafakwa zombane, kodwa endaweni ucingo lobhedu kwi eliphakathi iglasi ifayibha obhityileyo. Njengoko ukwambathisa yangaphakathi apha iglasi okanye esingxotyeni iplastiki leyo ethintela uphume njengokukhanya. Simele sithi wenza epheleleyo ibonisa ukukhanya ngokusebenzisa kwezinto ezimbini index ezahlukeneyo zokunganyangeki. Kakhulu ngamaxesha kusetyenziswa sheathing metal, njengoko yenza akukho ingqiqo ukukhusela ifayibha woqondo ukusuka ukuphazamiseka electromagnetic. Ukanti ngamanye amaxesha basebenzise ukhuseleko xa ufuna ukhuseleko ngoomatshini ukusuka kokusingqongileyo.
