I-ONT (i-Optical Network Terminal) kunye ne-transceiver ye-fiber optical zimbini izixhobo ezibalulekileyo kunxibelelwano lwefiber optical, kodwa zinokwahlukana okucacileyo kwimisebenzi, iimeko zesicelo kunye nokusebenza. Ngezantsi siza kuzithelekisa ngokweenkcukacha kwiinkalo ezininzi.
1. Inkcazo kunye nokusetyenziswa
ONT:Njengetheminali yothungelwano olubonayo, i-ONT isetyenziswa ikakhulu kwisixhobo se-terminal sothungelwano lofikelelo lwefiber optical (FTTH). Ifumaneka ekupheleni komsebenzisi kwaye inoxanduva lokuguqula imiqondiso yefiber optic ibe yimiqondiso yombane ukuze abasebenzisi bakwazi ukusebenzisa iinkonzo ezahlukeneyo ezifana ne-Intanethi, umnxeba kunye nomabonwakude. I-ONT ihlala ineendlela ezahlukeneyo zojongano, ezifana nojongano lwe-Ethernet, ujongano lwefowuni, ujongano lweTV, njl., ukuququzelela abasebenzisi ukudibanisa izixhobo ezahlukeneyo.
I-Optical fiber transceiver:I-fiber optic transceiver yiyunithi yokuguqula imidiya ye-Ethernet etshintshanisa umgama omfutshane ojijekileyo weempawu zombane kunye neempawu zombane ezikude. Ngokuqhelekileyo isetyenziselwa kwiindawo zenethiwekhi apho iintambo ze-Ethernet azikwazi ukugubungela kwaye i-fiber optical kufuneka isetyenziswe ukwandisa umgama wothumelo. Umsebenzi we-fiber optic transceiver kukuguqula izibonakaliso zombane zibe yimiqondiso ye-optical yokuhambisa umgama omde, okanye ukuguqula iimpawu ze-optical zibe iimpawu zombane ukuze zisetyenziswe ngabasebenzisi.

2. Umahluko osebenzayo
I-ONT:Ukongeza kumsebenzi wokuguqulwa kwe-photoelectric, i-ONT nayo inamandla okuphindaphinda kunye neempawu zedatha ye-demultiplex. Ngokuqhelekileyo inokusingatha izibini ezininzi zemigca ye-E1 kwaye iphumeze imisebenzi emininzi, njengokujonga amandla okukhanya, indawo ephosakeleyo kunye neminye imisebenzi yokulawula kunye nokubeka iliso. I-ONT yi-interface phakathi kwabanikezeli benkonzo ye-Intanethi (ISPs) kunye nabasebenzisi bokuphela kwe-fiber optic Internet, kwaye yinxalenye ebalulekileyo yenkqubo ye-intanethi ye-fiber optic.
I-Optical fiber transceiver:Yenza ubukhulu becala ukuguqulwa kwe-photoelectric, ayitshintshi i-encoding, kwaye ayenzi enye inkqubo kwidatha. I-Fiber optic transceivers zeze-Ethernet, zilandela iprotocol ye-802.3, kwaye zisetyenziselwa ikakhulu ukudityaniswa kwe-point-to-point. Isetyenziselwa kuphela ukuhanjiswa kweempawu ze-Ethernet kwaye inomsebenzi omnye.
3. Ukusebenza kunye nokulinganisa
I-ONT:Ngenxa yokuba i-ONT inamandla okuphindaphinda kunye neempawu zedatha ye-demultiplex, inokusingatha iiprotocol kunye neenkonzo ezininzi zothumelo. Ukongeza, i-ONT ihlala ixhasa amazinga aphezulu othumelo kunye nemigama emide yosulelo, enokufikelela kwiimfuno zabasebenzisi abaninzi.
I-Optical fiber transceiver:Ekubeni isetyenziselwa ukuguqulwa kwe-optical-to-electrical kwi-Ethernet, ilinganiselwe ngokwemigaqo yokusebenza kunye nokulinganisa. Ikakhulu isetyenziselwa ukudityaniswa kwe-point-to-point kwaye ayixhasi ukuhanjiswa kweebini ezininzi zemigca ye-E1.
Isishwankathelo, kukho ukungafani okucacileyo phakathi kwe-ONT kunye ne-optical fiber transceivers ngokwemigaqo yemisebenzi, iimeko zesicelo, kunye nokusebenza. Njenge-terminal network optical, i-ONT inemisebenzi emininzi kunye neemeko zesicelo kwaye ifanelekile kwiinethiwekhi zokufikelela kwi-fiber optical; ngelixa ii-transceivers ze-fiber optical zisetyenziselwa ukuhanjiswa kweempawu ze-Ethernet kwaye zinomsebenzi omnye. Xa ukhetha izixhobo, kufuneka ukhethe izixhobo ezifanelekileyo ngokusekelwe kwiimeko ezithile zesicelo kunye neemfuno.
