I-ONT (Optical Network Terminal) kanye ne-optical fiber transceiver kokubili kuyimishini ebalulekile ekuxhumaneni kwe-fiber optical, kodwa kunomehluko osobala emisebenzini, izimo zohlelo lokusebenza kanye nokusebenza. Ngezansi sizobaqhathanisa ngokuningiliziwe kusuka ezicini eziningi.
1. Incazelo kanye nokusebenza
ONT:Njengetheminali yenethiwekhi yokubona, i-ONT isetshenziselwa kakhulu okokusebenza kwetheminali yenethiwekhi yokufinyelela i-fiber optical (FTTH). Itholakala ekugcineni komsebenzisi futhi inomthwalo wemfanelo wokuguqula amasignali e-fiber optic abe amasignali kagesi ukuze abasebenzisi bakwazi ukusebenzisa izinsiza ezihlukahlukene njenge-inthanethi, ucingo nomabonakude. I-ONT ivamise ukuba nokuxhumana okuhlukahlukene, okufana nesixhumi esibonakalayo se-Ethernet, isixhumi esibonakalayo socingo, isixhumi esibonakalayo se-TV, njll., ukuze kube lula abasebenzisi ukuxhuma amadivaysi ahlukahlukene.
I-Optical fiber transceiver:I-fiber optic transceiver iyiyunithi yokuguqula imidiya ye-Ethernet eshintshanisa amasignali kagesi amabili asontekile amabanga amade kanye namasignali okubona amabanga amade. Ngokuvamile isetshenziswa ezindaweni zenethiwekhi lapho izintambo ze-Ethernet zingakwazi ukumboza futhi i-fiber optical kufanele isetshenziselwe ukunweba ibanga lokudlulisela. Umsebenzi we-fiber optic transceiver ukuguqula amasignali kagesi abe amasignali okukhanya ukuze adluliselwe ibanga elide, noma ukuguqula amasignali okukhanya abe amasignali kagesi ukuze asetshenziswe imishini yomsebenzisi.

2. Ukwehluka kokusebenza
ONT:Ngokungeziwe kumsebenzi wokuguqulwa kwe-photoelectric, i-ONT futhi inamandla okuphindaphinda nokukhipha amasiginali wedatha amaningi. Ngokuvamile ingakwazi ukuphatha amapheya amaningi emigqa ye-E1 futhi isebenzise imisebenzi eyengeziwe, njengokuqapha amandla okubona, indawo enephutha kanye neminye imisebenzi yokuphatha nokuqapha. I-ONT iwukuxhumana phakathi kwabahlinzeki besevisi ye-inthanethi (ama-ISP) kanye nabasebenzisi bokugcina be-inthanethi be-fiber optic, futhi iyingxenye ebalulekile yesistimu ye-intanethi ye-fiber optic.
I-Optical fiber transceiver:Ngokuyinhloko yenza ukuguqulwa kwe-photoelectric, ayishintshi umbhalo wekhodi, futhi ayenzi okunye ukucubungula kudatha. Ama-transceivers e-Fiber optic awe-Ethernet, alandela umthetho olandelwayo we-802.3, futhi asetshenziswa kakhulu ekuxhumekeni kokukhomba-kuya-phuzu. Isetshenziselwa kuphela ukudlulisa amasignali e-Ethernet futhi inomsebenzi owodwa uma kuqhathaniswa.
3. Ukusebenza kanye nokulinganisa
ONT:Ngenxa yokuthi i-ONT inamandla okuphindaphinda kanye ne-demultiplex amasiginali wedatha, ingakwazi ukuphatha amaphrothokholi amaningi okudlulisela namasevisi. Ngaphezu kwalokho, i-ONT ivamise ukusekela amazinga aphezulu okudlulisela kanye namabanga amade wokudlulisela, angahlangabezana nezidingo zabasebenzisi abaningi.
I-Optical fiber transceiver:Njengoba isetshenziselwa kakhulu ukuguqulwa kwe-optical-to-electrical ku-Ethernet, ilinganiselwe ngokuqhathaniswa nokusebenza kanye nokulinganisa. Ngokuyinhloko isetshenziselwa ukuxhumeka kwe-point-to-point futhi ayisekeli ukudluliswa kwamapheya amaningi wemigqa ye-E1.
Kafushane, kunomehluko osobala phakathi kwama-ONT nama-optical fibre transceivers ngokwemisebenzi, izimo zohlelo lokusebenza, kanye nokusebenza. Njengetheminali yenethiwekhi yokubona, i-ONT inemisebenzi eminingi kanye nezimo zohlelo lokusebenza futhi ifanele amanethiwekhi okufinyelela efiber optical; kuyilapho ama-transceivers e-fiber optical esetshenziselwa ukudluliselwa kwezimpawu ze-Ethernet futhi anomsebenzi owodwa ngokuqhathaniswa. Lapho ukhetha okokusebenza, udinga ukukhetha okokusebenza okufanele ngokusekelwe ezimeni ezithile zohlelo lokusebenza kanye nezidingo.
