Ukuqhathaniswa kokufinyelela kwe-FTTX okusekelwe ku-PON

Indlela yamanje yokufinyelela komkhawulokudonsa ophezulu isekelwe ngokuyinhloko ekufinyeleleni kwe-FTTX okusekelwe ku-PON. Izici eziyinhloko nokuqagela okuhilelekile ekuhlaziyeni izindleko kungokulandelayo:

● Izindleko zemishini yesigaba sokufinyelela (okuhlanganisa amathuluzi okufinyelela ahlukahlukene nemigqa, njll., elinganiselwe kumsebenzisi ngamunye wolayini)

● Izindleko zokwakha zobunjiniyela (okuhlanganisa izimali zokwakha kanye nezinye izindleko ezingaphezulu, ngokuvamile ezingu-30% yenani lesamba lesisetshenziswa)

● Izindleko zokusebenza nezokulungisa (imvamisa ziba ngu-8% wesamba sezindleko ngonyaka)

●Izinga lokufaka alicatshangwa (okungukuthi, izinga lokufaka ngu-100%).

● Izindleko zemishini edingekayo zibalwa ngokusekelwe kumamodeli wabasebenzisi abangu-500

Qaphela 1: Ukufinyelela kwe-FTTX akucabangi izindleko zegumbi lekhompyutha yomphakathi;

Qaphela 2: I-ADSL2+ ayinayo inzuzo uma iqhathaniswa ne-ADSL uma ibanga lokufinyelela lingu-3km. I-VDSL2 okwamanje ayisetshenziswa kabanzi, ngakho-ke akukho ukuqhathanisa okuzokwenziwa okwamanje;

Qaphela 3: Ukufinyelela i-Optical fiber kunezinzuzo ezisobala emabangeni amade.

I-FTTB+LAN

Ihhovisi elimaphakathi lihanjiswa nge-optical fiber (3km) ukuya ekuhlanganiswenishintshayendawo yokuhlala noma isakhiwo, bese ixhunywa emhubhenishintshange-optical fiber (0.95km), bese ihanjiswa ekupheleni komsebenzisi kusetshenziswa ikhebula yeSigaba 5 (0.05km). Kubalwe ngokuya ngemodeli yomsebenzisi engu-500 (ngaphandle kokucabangela izindleko zegumbi lamaseli), okungenani ukuhlanganisa okukodwa kwezimbobo ezingama-24shintshakanye nomhubhe wamachweba angama-21 24amaswishiziyadingeka. Ekusetshenzisweni kwangempela, izinga elengeziwe leshintshangokuvamile yengezwa. Nakuba inani eliphelele leamaswishiukwanda, ukusetshenziswa kwamamodeli anenani eliphansi lephasejiamaswishikunciphisa izindleko eziphelele.

I-FTTH

Cabangela ukubeka iOLTehhovisi elimaphakathi, i-single optical fiber (4km) eya egumbini lekhompiyutha eliphakathi nendawo, egumbini lekhompyutha eliphakathi nendawo ngokusebenzisa isihlukanisi esingu-1:4 (0.8km) ukuya ephaseji, kanye nesihlukanisi esingu-1:8 optical (0.2km ) kutheminali yomsebenzisi wephaseji. Kubalwe ngokwemodeli yabasebenzisi abangu-500 (ngaphandle kokucabangela izindleko zegumbi lamaseli): Izindleko zeOLTimishini yabelwe esikalini sabasebenzisi abangama-500, edinga isamba esingu-16OLTamachweba.

I-FTTC+EPON+LAN

Futhi cabanga ukubeka iOLTehhovisi elikhulu. I-single optical fiber (4km) izothunyelwa ekamelweni lekhompyutha elimaphakathi lomphakathi. Igumbi lekhompiyutha elimaphakathi lomphakathi lizodlula endaweni eyi-1:4 optical splitter (0.8km) liye esakhiweni. Ephaseji ngalinye, kuzosetshenziswa i-optical splitter engu-1:8 (0.2km). ) Iya esitezi ngasinye, bese uxhuma kutheminali yomsebenzisi ngemigqa Yesigaba 5. NgamunyeI-ONUinomsebenzi wokushintsha u-Layer 2. Ngokucabangela ukuthiI-ONUifakwe amachweba angu-16 FE, okungukuthi, ngalinyeI-ONUingafinyelela kubasebenzisi abayi-16, abalwa ngokwemodeli yabasebenzisi abangama-500.

I-FTTC+EPON+ADSL/ADSL2+

Ukuze usebenzise okufanayo kwe-DSLAM eyehlayo, cabanga ukubeka i-OLTehhovisi elimaphakathi, kanye nefayibha eyodwa (5km) ukusuka ehhovisi lokugcina le-BAS ukuya ehhovisi elivamile lokugcina, futhi ehhovisi elivamile, lidlula ku-1:8 optical splitter (4km) ukuyaI-ONUekamelweni lekhompyutha eliphakathi nendawo. II-ONUixhunywe ngokuqondile ku-DSLAM ngesixhumi esibonakalayo se-FE, bese ixhunywa ekugcineni komsebenzisi ngekhebula lethusi elisontekile (1km). Iphinde ibalwa ngokusekelwe kumodeli yabasebenzisi abangu-500 exhunywe ku-DSLAM ngayinye (ngaphandle kokucabangela izindleko zegumbi leseli).

I-Ethernet ye-point-to-point optical

Ihhovisi elimaphakathi lisatshalaliswa nge-optical fiber (4km) ukuhlanganisashintshayomphakathi noma isakhiwo, bese kuthunyelwa ngqo ekugcineni komsebenzisi nge-fiber optical (1km). Kubalwe ngokuya ngemodeli yabasebenzisi abangu-500 (ngaphandle kokucabangela izindleko zegumbi lamaseli), okungenani ukuhlanganisa kwezimbobo ezingama-21 24amaswishiKudingeka, futhi amapheya angama-21 angamakhilomitha angu-4 emicu yokubona yomgogodla abekwa esuka egumbini lekhompyutha lehhovisi eliphakathi kuya ekuhlanganisweni.amaswishiesitokisini. Njengoba i-point-to-point optical Ethernet ivame ukusetshenziselwa ukufinyelela kwe-broadband ezindaweni zokuhlala, ngokuvamile isetshenziselwa ukuxhumanisa abasebenzisi ababalulekile abahlakazekile. Ngakho-ke, umnyango wayo wokwakha uhlukile kwezinye izindlela zokufinyelela, ngakho-ke izindlela zokubala nazo zihlukile.

Kusukela ekuhlaziyweni okungenhla, kungabonakala ukuthi ukubekwa kwe-splitter ye-optical kuzoba nomthelela oqondile ekusetshenzisweni kwe-fiber, okuphinde kuthinte izindleko zokwakha inethiwekhi; izindleko zamanje zemishini ye-EPON zinqunyelwe ngokuyinhloko imojula yokudlulisa amehlo eqhumayo/yokwamukela futhi amanani emojula yokulawula ama-Chips kanye ne-E-PON ahlala ehliswa ukuze ahlangabezane nezidingo zemakethe; uma kuqhathaniswa ne-xDSL, izindleko zokufaka zesikhathi esisodwa ze-PON ziphezulu, futhi okwamanje isetshenziswa kakhulu ezindaweni zabasebenzisi ezisanda kwakhiwa noma ezakhiwe kabusha eziminyene. I-Point-to-point Optical Ethernet ifaneleka kuphela kumakhasimende ahlakazekile kahulumeni nawebhizinisi ngenxa yezindleko zayo eziphezulu. Ukusebenzisa i-FTTC+E-PON+LAN noma i-FTTC+EPON+DSL kuyisixazululo esingcono sokudlulela kancane kancane ku-FTTH.
