Ngophuhliso lwetekhnoloji yedijithali, itekhnoloji yonxibelelwano olubonakalayo kunye netekhnoloji yesoftware kunye nokusetyenziswa okubanzi kweprotocol ye-TCP/IP, inethiwekhi yonxibelelwano, inethiwekhi yekhompyuter kunye nothungelwano lukamabonwakude luya kudibana kunye kwaye lumanyene phantsi kwe-IP ekwaziyo ukubonelela ngelizwi, idatha kunye nemifanekiso kwi. kwangelo xesha linye inethiwekhi yonxibelelwano yemultimedia yeBroadband yeshishini.Ukufikelela kocingo lobhedu lwangoku, ukufikelela kwi-wireless, kunye neendlela zokufikelela kwi-LAN akulula ukufezekisa le njongo, kodwa kulula kwi-FTTH.
I-FTTH ayiboneleli nje kuphela i-bandwidth enkulu, kodwa iphucula ukucaca kothungelwano kwiifomathi zedatha, iireyithi, ubude bamaza kunye neeprothokholi, ikhulula iimfuno zokusingqongileyo kunye nonikezelo lwamandla, yenza lula ukugcinwa kunye nofakelo, kwaye inamandla okusasaza idatha ye-TDM, IP kunye nevidiyo ngaxeshanye Ikhono leenkonzo zokusasaza, apho i-TDM kunye nedatha ye-IP zihanjiswa kwifomathi ye-IEEE802.3 Ethernet, incediswa yinkqubo yolawulo lwenethiwekhi ye-carrier-grade, ngokwaneleyo ukuqinisekisa umgangatho wokuhambisa, kunye nokusasazwa kwevidiyo kunokufezekiswa. usebenzisa i-wavelength yesithathu (ngokuqhelekileyo i-1550nm) Ukuhanjiswa kweShishini.
Iteknoloji yokufikelela kwi-fiber optical ngokwenene isisombululo esisebenzisa yonke okanye inxalenye yefiber optical kwinethiwekhi yokufikelela ukwenza i-fiber optical subscriber loop (FITL), okanye i-fiber optical access network (OAN), ukufikelela kwi-broadband access.
Ngokwendawo ye-ONU, i-fiber access network yahlulwe yaba yifayibha kwi-desktop (FTTD), ifayibha ukuya kwikhaya (FTTH), ifayibha ukuya kungqameko (FTTC), ifayibha kwisakhiwo (FTTB), ifayibha ukuya ofisi (FTTO), ifayibha ukuya emgangathweni (FTTF), ifayibha kwiseli (FTTZ) kunye nezinye iintlobo.Phakathi kwazo, i-FTTH iya kuba yindlela yokugqibela yophuhliso lwenethiwekhi yokufikelela kwi-broadband kwixesha elizayo.I-FTTH ibhekisa kufakelo lweeyunithi zothungelwano lwamehlo (ONUs) kwindawo yokuhlala okanye yabasebenzisi beshishini.Luhlobo lwenethiwekhi yokufikelela kwi-optical ekufutshane kubasebenzisi kwi-FTTx series ngaphandle kwe-FTTD.
Izinto eziza kuqwalaselwa kuphuhliso lweFTTH
Nangona i-FTTH ikhulile ngokobuchwephesha kwaye inokwenzeka, kwaye ixabiso leendleko lihlala lisihla, kusekho imingeni emininzi yokuphumeza usetyenziso olukhulu lwe-FTTH kwilizwe lam.
Umba weendleko
Okwangoku, ngaphezu kwe-97% yothungelwano lokufikelela kwi-FTTH kwihlabathi lubonelela kuphela ngeenkonzo zokufikelela kwi-Intanethi, kuba iindleko zokubonelela ngeefowuni zemveli ezisisigxina nge-FTTH ziphezulu kakhulu kuneendleko zeteknoloji yefowuni ekhoyo esisigxina, kunye nokusetyenziswa kwe-fiber optical ukudlulisa. iminxeba esisigxina yemveli nayo inengxaki yonikezelo lwamandla efowuni.Namhlanje, inethiwekhi yocingo lobhedu isabambe isikhundla esikhulu.ukusetyenziswa kwethekhnoloji ye-ADSL yenza ulwakhiwo lweprojekthi lube lula, lungabizi, kwaye lukwazi ukuhlangabezana neemfuno zeshishini langoku.Ngoyena mntu ukhuphisana naye kwi-FTTH kweli nqanaba.
Imiba yomgaqo-nkqubo
Kusekho imiqobo yoshishino ekufuneni ukufikelela kwinkonzo epheleleyo ye-FTTH kwilizwe lam, oko kukuthi, abaqhubi be-telecom abavumelekanga ukuba baqhube iinkonzo ze-CATV, ngokuchaseneyo, abaqhubi be-CATV abavumelekanga ukuba baqhube iinkonzo ze-telecom zendabuko (ezifana nomnxeba), kwaye le meko ayinakuguqulwa ixesha elide kwixesha elizayo Ngoko ke, umqhubi omnye akanako ukubonelela ngeenkonzo zokudlala kathathu kwinethiwekhi yokufikelela ye-FTTH.
Ukuhambelana kwe-ONU kunye nokusebenzisana
Ukuhambelana kwe-ONU kudlala indima ebalulekileyo ekuphuhliseni nasekuphuculeni lonke ikhonkco loshishino lwe-FTTH.Ukusetyenziswa kwesikali se-FTTH kunye nonyuso kusafuneka kuphuculwe imigangatho yoshishino ngokukhawuleza.Abavelisi bezixhobo kufuneka basebenzisane nemibutho yokubeka emgangathweni, abaqhubi, abavelisi bezixhobo kunye namasebe oyilo ukuze kugxininiswe kwimiba emithandathu ebandakanya imigangatho yobugcisa benkqubo, imigangatho yobugcisa yesixhobo se-FTTH, imigangatho yobugcisa ye-FTTH yentambo yokubona, imigangatho yobugcisa ye-FTTH yobunjineli, imigangatho yokwakha yobunjineli ye-FTTH kunye novavanyo lwe-FTTH. imigangatho.Kwelinye icala, qulunqa ngokubanzi imigangatho yobugcisa yoshishino lweFTTH kunye neenkcukacha ukukhokela izicelo zeFTTH.
Umthamo weshishini elithile
Ukungabikho kwesicelo yinto ebalulekileyo echaphazela uphuhliso olongezelelweyo lweFTTH.Ukuba usefa kwi-Intanethi, isantya se-1M se-ADSL siyakwanela.Nangona kunjalo, xa imfuno yeenkonzo isanda, njengeTV yedijithali, iVOD, iinkonzo zevidiyo ebanzi, kunye neevidiyo ezikumgangatho ophezulu, ukuthengwa kwe-intanethi, iinkonzo zonyango kwi-intanethi, njl., i-bandwidth ye-1M ngokuqinisekileyo ayinakukwazi ukuyixhasa, kunye ne-DSL. asiyi kukwazi ukwenza oko., FTTH inendawo yayo.Ke ngoko, uphuhliso lweenkonzo zebroadband yeyona nto ibalulekileyo yokuqhuba uphuhliso lweFTTH.
Inqanaba lokusetyenziswa kweenkonzo zonxibelelwano kwilizwe lam liphantsi ngokubanzi.Okwangoku, bambalwa kakhulu abasebenzisi borhwebo be-FTTH (phantse zero), kwaye unyuso lwe-FTTH lusebutsheni bayo.Ngesi sizathu, ukukhetha itekhnoloji ye-FTTH efanele iimeko zelizwe lethu kubaluleke kakhulu ukukhuthaza ukuthandwa kwe-FTTH kwilizwe lethu.Ngokwandiswa kwesikali sesicelo, ixabiso lezixhobo zeFTTH linendawo enkulu yokunciphisa.Kwixesha elizayo, imakethi ye-broadband iya kuhlala kunye ne-ADSL, i-FTTB + LAN, kunye ne-FTTH ngexesha elithile.I-ADSL iya kuqhubeka nokuba yeyona nto iphambili ngexesha elifutshane.I-DSL kunye ne-FTTH ziya kuphuhlisa kunye.Xa ixabiso lezixhobo ze-FTTH lincitshiswa ngokuthe ngcembe kwi-DSL ngenxa yokunyuka komthamo wokwakha Umthamo wemarike we-FTTH uya kunyuka kakhulu xa izinga liphezulu.
