Kuqoqosho lwedijithali lwanamhlanje, ukusebenzisa amandla ngendlela efanelekileyo akusekho nto ibalulekileyo—kuba yinto ebalulekileyo ekucwangcisweni kweziseko zophuhliso. Njengoko amaziko edatha esanda kwaye ithrafikhi yehlabathi iqhubeka nokwanda, ukhetho phakathi kwe-fiber optic kunye ne-copper cables luhlolwa kwakhona ngelensi yozinzo.
I-Oyi International, Ltd.,eseShenzhenintambo ye-fiber opticUmvelisi owasekwa ngo-2006, uchithe phantse amashumi amabini eminyaka enikezela ngezisombululo zonxibelelwano ezisebenzayo kwihlabathi liphela. Njengoko ingqalelo ikhula kwimpembelelo yokusingqongileyo, umbuzo awusekho malunga nesantya okanye i-bandwidth—kodwa loluphi ubuchwepheshe obuxhasa ngokwenene inethiwekhi eluhlaza.
Ukufakwa kweentambo zekopolo kudala kwaba ngumgangatho kwiziseko zophuhliso lwenethiwekhi, kodwa imida yayo iya icaca ngakumbi. Ngenxa yokuba ikopolo idlulisela idatha isebenzisa imiqondiso yombane, ukumelana akunakuphepheka. Oku kuxhathisa kuvelisa ubushushu, obunganyusi nje kuphela ukusetyenziswa kwamandla ngexesha lokudlulisa kodwa bukwanyusa neemfuno zokupholisa—ingakumbi kwiindawo ezinkulu ezifanaamaziko edatha.
I-fiber opticsisebenza ngendlela eyahlukileyo. Ngokuthumela idatha njengokukhanya, ifayibha ithintela ukuxhathisa kombane ngokupheleleyo. Isiphumo kukuba ukusetyenziswa kwamandla okuphantsi kakhulu ngesuntswana yedatha, kunye nokuveliswa kobushushu okuncinci. Ngokwendlela esebenzayo, oku kuthetha ukuba kufuneka amandla amancinci ukuhambisa idatha engaphezulu, kwaye amandla amancinci achithwa kwiinkqubo zokupholisa.
Umgama yenye into apho umahluko ucaca khona. Iintambo zekopolo, ezifana neCat6 okanye iCat6a, zihlala zixhasa umgama wokudlulisa ukuya kuthi ga kwiimitha ezili-100 ngaphambi kokuba kufuneke izixhobo ezongezelelweyo ezifana neeswitshi okanye iziphindaphindi. Isixhobo ngasinye esongeziweyo sisebenzisa amandla kwaye sonyusa ubunzima benkqubo.
Iintambo ze-fiber optic, ingakumbi ifayibha yemowudi enye, inokuthwala imiqondiso edlula amashumi eekhilomitha ngelahleko encinci. Izinto ezimbalwa ezisebenzayo ziguqulela ngokuthe ngqo ekusetyenzisweni kwamandla okuphantsi kunye nokugcinwa okuncitshisiweyo—inzuzo eba yinto ebaluleke ngakumbi kwiinethiwekhi zekhampasi, iinkqubo zemetro, kunye nonxibelelwano olude.
Ukupholisa, okuhlala kungajongwa kuyilo lwenethiwekhi, kudlala indima enkulu ekusetyenzisweni kwamandla ngokubanzi. Kwiziko ezininzi zedatha, ukupholisa kufikelela kwi-30–40% yamandla apheleleyo asetyenziswayo. Iinkqubo ezisekwe kubhedu zivame ukuvelisa ubushushu obuninzi, nto leyo eyonyusa imfuno yokupholisa. Ifayibha, enemveliso yayo ephantsi yobushushu, inceda ukunciphisa lo mthwalo kwaye iphucule ukusebenza kakuhle ngokubanzi.
Ngokwembono yobomi, ubhedu luyazuza kwinkqubo yokusetyenziswa kwakhona evuthiweyo. Nangona kunjalo, iindleko zokwemba nokucoca ubhedu zinkulu kakhulu kwindalo esingqongileyo. Ifayibha, eyenziwe ngokuyintloko nge-silica ephuma kwisanti, inika iprofayili eyahlukileyo yozinzo. Nangona imveliso yayo ifuna ukuchaneka kunye namandla, ubomi obude befayibha kunye nomthamo ophezulu kunciphisa isidingo sokuhlaziywa rhoqo. Ngokuhamba kwexesha, oku kukhokelela ekusetyenzisweni kwamandla aphantsi kuyo yonke inethiwekhi.
Kusekho iimeko apho i-copper inengqiqo. Kwimigama emifutshane kakhulu eneemfuno ze-bandwidth ezincinci, ihlala iyindlela engabizi kakhulu. Nangona kunjalo, njengoko ubuchwepheshe obufana neenethiwekhi ze-optical ezingasebenziyo (i-PON) buqhubeka buphucula, neendawo zokuhlala kunye nezoshishino ezincinci ziyatshintsha.ukuya kwifayibhaizisombululo ezisekelwe kuzo.
Kwizicelo ze-bandwidth ephezulu, uthumelo olude, amaziko edatha, kunye ne-5G backhaul, i-fiber sele ibe lukhetho olukhethwayo—kungekuphela nje ekusebenzeni, kodwa nasekusebenzeni kakuhle. Utshintsho oluqhubekayo, kuquka iimodyuli ze-optical ezinamandla aphantsi, luyaqhubeka nokunyusa iingenelo zamandla ze-fiber nangakumbi.
Ekugqibeleni, indlela icacile. Njengoko iinethiwekhi zitshintsha ukuze zihlangabezane neemfuno ezikhulayo, ii-fiber optics ziyavela njengesisombululo esisebenza kakuhle kwaye sihlala ixesha elide. Ukulahleka okuncinci kothumelo, iimfuno eziphantsi zokupholisa, kunye nomjikelo wobomi obude zonke ezi zinto zinegalelo kwindawo yazo njengeziseko zexesha elizayo.
I-Oyi International, Ltd. isazimisele ukuxhasa olu tshintsho. Ukusuka kwi-FTTHlahla iintamboKwizisombululo zeziko ledatha elinoxinano olukhulu, i-OYI ibonelela ngeemveliso ze-fiber optic ezenzelwe ukonga ukusebenza kunye namandla. Kumashishini afuna ukwakha iinethiwekhi ezisebenzayo nezizinzileyo, i-fiber ayiselulo ukhetho nje kuphela—linyathelo elilandelayo elinengqondo.
