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-fiber optical (3km) kuya ekushintsheni kokuhlanganisa kwendawo okuhlala kuyo noma isakhiwo, bese lixhunywa ephasejini ngefiber optical (0.95km), bese liyiswa ekugcineni komsebenzisi kusetshenziswa ikhebula leSigaba 5 (0.05) km).Kubalwe ngokwemodeli yabasebenzisi abangu-500 (ngaphandle kokucabangela izindleko zegumbi leselula), okungenani inkinobho eyodwa yokuhlanganisa amachweba angama-24 kanye namaswishi angama-21-24-corridor ayadingeka.Ekusetshenzisweni kwangempela, izinga elengeziwe lokushintsha ngokuvamile liyengezwa.Nakuba inani eliphelele lokushintsha likhuphuka, ukusetshenziswa kwamamodeli anenani eliphansi lamaswishi ephaseji kunciphisa inani lezindleko.

I-FTTH

Cabangela ukubeka i-OLT ehhovisi elimaphakathi, i-single optical fiber (4km) egumbini lekhompiyutha elimaphakathi, egumbini lekhompyutha elimaphakathi neseli ngokusebenzisa isihlukanisi esibonakalayo esingu-1:4 (0.8km) ukuya ephasishi, kanye ne-optical engu-1:8. isihlukanisi (0.2km) kutheminali yomsebenzisi wephaseji.Kubalwe ngokuya ngemodeli yabasebenzisi abangu-500 (ngaphandle kokucabangela izindleko zegumbi lamaseli): Izindleko zempahla ye-OLT zabelwa esikalini sabasebenzisi abangama-500, ezidinga isamba samachweba we-OLT ayi-16.

I-FTTC+EPON+LAN

Futhi cabanga ngokubeka i-OLT ehhovisi 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.I-ONU ngayinye inomsebenzi wokushintsha u-Layer 2.Uma kucatshangelwa ukuthi i-ONU ifakwe amachweba angu-16 FE, okungukuthi, i-ONU ngayinye ingakwazi ukufinyelela abasebenzisi abangu-16, abalwa ngokuvumelana nemodeli yabasebenzisi abangu-500.

I-FTTC+EPON+ADSL/ADSL2+

Ngokusetshenziswa okufanayo kwe-DSLAM eyehlayo, cabanga ukubeka i-OLT ehhovisi elimaphakathi, kanye nefayibha eyodwa (5km) ukusuka ehhovisi lokugcina le-BAS ukuya ehhovisi elivamile lokugcina, futhi ehhovisi eliphelele, lidlula ku-optical 1:8. i-splitter (4km) eya ku-ONU egumbini lekhompyutha eliphakathi nendawo.I-ONU ixhumeke ngokuqondile ku-DSLAM ngesixhumi esibonakalayo se-FE, bese ixhunywa ekugcineni komsebenzisi ngentambo yethusi ephothiwe (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 lisebenzisa i-optical fiber (4km) ekushintsheni kokuhlanganisayo komphakathi noma kwesakhiwo, bese kuthunyelwa ngokuqondile ekugcineni komsebenzisi nge-optical fiber (1km).Kubalwa ngokwemodeli yomsebenzisi engama-500 (ngaphandle kokubheka izindleko zegumbi lamaseli), okungenani ama-switch aggregation angama-21 24-port ayadingeka, futhi amapheya angu-21 amakhilomitha angu-4 emicu optical optical abekwa esuka ehhovisi elimaphakathi lekhompiyutha kuya ekuhlanganisweni. amaswishi kuseli.Njengoba i-point-to-point optical Ethernet ngokuvamile ingasetshenziselwa 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, okuthinta nezindleko 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 sokushintshela ku-FTTH kancane kancane.
