Ngokuthuthuka kobuchwepheshe bedijithali, ubuchwepheshe bokuxhumana obubonakalayo kanye nobuchwepheshe besoftware kanye nokusetshenziswa okubanzi kwephrothokholi ye-TCP/IP, inethiwekhi yezokuxhumana, inethiwekhi yekhompiyutha kanye nenethiwekhi yethelevishini izohlangana futhi ibe munye ngaphansi kwe-IP ekwazi ukuhlinzeka ngezwi, idatha nezithombe ku- ngesikhathi esifanayo inethiwekhi yokuxhumana ye-multimedia ye-Broadband yebhizinisi. Ukufinyelela kwezintambo zethusi kwamanje, ukufinyelela okungenantambo, nezindlela zokufinyelela ku-LAN akulula ukufeza lo mgomo, kodwa kulula ku-FTTH.

I-FTTH ayihlinzeki nje kuphela ngomkhawulokudonsa omkhulu, kodwa futhi ithuthukisa ukucaca kwenethiwekhi kumafomethi edatha, amanani, ubude begagasi nezivumelwano, iphumuza izimfuneko zemvelo namandla, yenza ukugcinwa nokufakwa kube lula, futhi inamandla okudlulisa idatha ye-TDM,IP kanye nevidiyo kanyekanye Amandla ezinsizakalo zokusakaza, lapho idatha ye-TDM kanye ne-IP isakazwa ngefomethi ye-IEEE802.3 Ethernet, yengezwe uhlelo lokuphatha inethiwekhi yenkampani yenethiwekhi, okwanele ukuqinisekisa ikhwalithi yokudlulisela, kanye nokusakazwa kwevidiyo kungenziwa usebenzisa i-wavelength yesithathu (imvamisa engu-1550nm) Ukudluliselwa kwebhizinisi.

Ubuchwepheshe bokufinyelela i-fiber optical empeleni yisixazululo esisebenzisa yonke noma ingxenye ye-fiber optical kunethiwekhi yokufinyelela ukuze kwakhiwe i-optical fiber subscriber loop (FITL), noma i-optical fiber access network (OAN), ukuze kuzuzwe ukufinyelela kwe-broadband.

Ngokusho kwendawo ye-I-ONU, i-fiber access network ihlukaniswe yaba i-fiber to the desktop (FTTD), fibre to the home (FTTH), fibre to the curb (FTTC), fibre to the building (FTTB), fibre to the office (FTTO), fibre to the phansi (FTTF), i-fiber kuseli (FTTZ) nezinye izinhlobo. Phakathi kwazo, i-FTTH izoba wuhlobo lokugcina lokuthuthukiswa kwenethiwekhi ye-broadband yesikhathi esizayo. I-FTTH isho ukufakwa kwamayunithi enethiwekhi optical (ONUs) kubasebenzisi bezindawo zokuhlala noma zezinkampani. Iwuhlobo lwenethiwekhi yokufinyelela yokubona eseduze kakhulu nabasebenzisi ochungechungeni lwe-FTTx ngaphandle kwe-FTTD.

Izinto okufanele zicatshangelwe ekuthuthukisweni kwe-FTTH

Nakuba i-FTTH ivuthiwe ngokobuchwepheshe futhi kungenzeka, futhi intengo yezindleko ihlale yehla, kusenezinselele eziningi zokufeza ukusetshenziswa kwezinga elikhulu kwe-FTTH ezweni lami.

Indaba yezindleko

Njengamanje, ngaphezu kwe-97% yamanethiwekhi okufinyelela e-FTTH emhlabeni ahlinzeka ngezinsizakalo zokufinyelela ku-inthanethi kuphela, ngoba izindleko zokuhlinzeka ngocingo olungaguquki lwendabuko nge-FTTH ziphakeme kakhulu kunezindleko zobuchwepheshe befoni obungaguquki obukhona, kanye nokusetshenziswa kwe-fiber optical ukudlulisa. izingcingo ezingaguquki zendabuko nazo zinenkinga yokunikezwa kwamandla ocingo. Namuhla, inethiwekhi yocingo lwethusi isabambe isikhundla esikhulu.ukusetshenziswa kobuchwepheshe be-ADSL kwenza ukwakhiwa kwephrojekthi kube lula, kushibhile, futhi kungahlangabezana nezidingo zebhizinisi lamanje. Iyimbangi enkulu ye-FTTH kulesi sigaba.

Izici zenqubomgomo

Kusenezithiyo zezimboni ekuphishekeleni ukufinyelela kwenkonzo egcwele ye-FTTH ezweni lami, okungukuthi, opharetha bezingcingo abavunyelwe ukusebenzisa izinsizakalo ze-CATV, ngokuphambene nalokho, opharetha be-CATV abavunyelwe ukusebenzisa izinsizakalo zokuxhumana zendabuko (ezifana nocingo), futhi lesi simo asikwazi ukushintshwa isikhathi eside esikhathini esizayo Ngakho-ke, u-opharetha oyedwa akakwazi ukuhlinzeka ngezinsizakalo zokudlala kathathu kunethiwekhi yokufinyelela ye-FTTH.

I-ONUukuhambisana nokusebenzisana

Ukuhambisana kweI-ONUidlala indima ebalulekile ekuthuthukisweni nasekuthuthukisweni kwawo wonke uchungechunge lwezimboni ze-FTTH. Isicelo sesikali se-FTTH nokukhushulwa kusadinga ukuthuthukisa amazinga emboni ngokushesha okukhulu. Abakhiqizi bezinto zokusebenza kufanele basebenzisane nezinhlangano zokuma, opharetha, abakhiqizi bemishini neminyango yokuklama ukuze bagxile ezicini eziyisithupha ezihlanganisa amazinga obuchwepheshe besistimu, amazinga obuchwepheshe bedivayisi ye-FTTH, amazinga obuchwepheshe ekhebula elikhanyayo le-FTTH, izindinganiso zezobuchwepheshe ezisekela ubunjiniyela be-FTTH, amazinga obuchwepheshe e-FTTH engineering kanye nokuhlolwa kwe-FTTH. izindinganiso. Ngakolunye uhlangothi, yakha ngokugcwele amazinga obuchwepheshe bemboni ye-FTTH kanye nokucaciswa ukuze uqondise izinhlelo zokusebenza ze-FTTH.

Umthamo webhizinisi othize

Ukuntuleka kwesicelo kuyisici esibalulekile esithinta ukuthuthukiswa okuqhubekayo kwe-FTTH. Uma uvele usebenzise i-inthanethi, isivinini esingu-1M ADSL sizokwanela. Kodwa-ke, uma isidingo sezinsizakalo senyuka, njenge-TV yedijithali, i-VOD, izinsizakalo zevidiyo ye-broadband, namafoni evidiyo ekhwalithi ephezulu, ukuthenga ku-inthanethi, izinsizakalo zezokwelapha eziku-inthanethi, njll., umkhawulokudonsa ongu-1M ngeke neze ukwazi ukukusekela, futhi i-DSL angeke akwazi ukwenza njalo. , i-FTTH inendawo yayo. Ngakho-ke, ukuthuthukiswa kwezinsizakalo ze-broadband kungamandla abalulekile okuqhuba ukuthuthukiswa kwe-FTTH.

Izinga lokusetshenziswa kwezinsiza ze-telecom ezweni lami ngokuvamile liphansi. Okwamanje, bambalwa kakhulu abasebenzisi bezentengiselwano be-FTTH (cishe iqanda), futhi ukukhushulwa kwe-FTTH kusaqala. Ngalesi sizathu, ukukhetha ubuchwepheshe be-FTTH obufanele izimo zezwe lethu kubaluleke kakhulu ukukhuthaza ukuthandwa kwe-FTTH ezweni lethu. Ngokunwetshwa kwesikali sohlelo lokusebenza, izindleko zemishini ye-FTTH zinendawo enkulu yokwehliswa. Ngokuzayo, imakethe ye-broadband izoba kanye ne-ADSL, FTTB+LAN, kanye ne-FTTH phakathi nenkathi ethile yesikhathi. I-ADSL izoqhubeka nokuba yingosi ngesikhathi esifushane. I-DSL ne-FTTH zizothuthuka ndawonye. Lapho intengo yemishini ye-FTTH yehliswa kancane kancane ibe yi-DSL ngenxa yokwanda kwevolumu yokwakha Umthamo wemakethe ye-FTTH uzokhula kakhulu lapho izinga liphezulu.
