Iteknoloji FTTx - lwe Internet

iinkampani abaninzi baqala kancinci ukuya usebenzisa iteknoloji FTTx njengesiseko ubonelelo ngeenkonzo ukufikelela Internet. Ngoku, andithethi nto nje kunzima yaye kuziindleko njengoko kwakunjalo kwiminyaka embalwa eyadlulayo. Kungenxa yoko le nto imveliso zabo eli inkqubela emarikeni.

Yintoni na?

Ukusebenzisa iteknoloji FTTx ibandakanya nokutsala izisombululo fibre optic ulwakhiwo lothungelwano lwebhendi ebanzi. Kufuneka uchaze oko kuthethwa ngulo ayilogama litsha.

FTTx - igama elichaza indlela jikelele ukuba kusekwe izibonelelo inethiwekhi yentambo, apho unxibelelwano ukusuka esiludumbo kwindawo ethile, nezaziwa «x», kuza optic, uze ngqo kubathengi, cable Nobhedu ilele. Kungenzeka kwacaba ngokukhanya ngqo kwifowuni isikhokhelo ngayo. Ubukhulu becala, ukusetyenziswa kobugcisa FTTx ibandakanya kuphela umaleko emzimbeni. Kodwa phantsi le ngcamango liyalahleka kunye nenani elikhulu lobuchwepheshe womnatha kunye data likhonkco umaleko. Broadband ivumela ukuba zinika inani iinkonzo ezintsha.

Umdla networks ezinjalo

Okwangoku, njengoko imarike engundoqo injini FTTx ekuthiwa imfuno sesininzi ufikelelo broadband, kwaye kunzima kakhulu ukufikelela, ukuba nje ukusebenzisa ADSL. izisombululo Optical aye ngokuya lilungiswe kwizixeko ezinkulu, kwaye kukho umkhwa ecacileyo ukuze uhlangane abasebenzi ezincinane ukuba nkulu, apho basebenza kwinqanaba federal. technology FTTx ngokubanzi kakhulu asetyenziswe ezilalini, apho izibonelelo ekuqaleni kwakhiwa ngokusekelwe endleleni optical.

amathuba market

Uphuhliso market FTTx kwi kwintsimi Russian kuxhomekeke kuphela kwi imfuno umxholo ezikumgangatho ophezulu, kodwa kwakhona kwinani lamaphulo zokwakha ezinkulu, kwakunye nokwanda ukhuphiswano phakathi kwababoneleli beenkonzo lwebhendi ebanzi. Ngenxa lokhwakha izakhiwo zokuhlala akhande uthungelwano FTTx uba ngokukhawuleza kakhulu kwaye ubengokufaneleyo malunga noqoqosho, kwaye khuphiswano ukwenza, ukuze iindleko ukufikelela kwi-Internet ufumana asezantsi. Kwiminyaka embalwa edlulileyo, ingqalelo abasebenzi 'babujoliswe ngumthengi loshishino, yaye ngoku bonganyelwe ingqalelo ababhalisayo eziqhelekileyo.

ngokukodwa

technology FTTx de kutshanje ezisetyenziswa ngabaqhubi abangazange babe isizukulwana endala lwezibonelelo zabo, ukuba yenziwe ngobhedu, yaye oku ngenxa yeendleko nokunyuka isakhiwo lokusekwa ifayibha. Noko ke, kule minyaka imbalwa idlulileyo, umdla uthungelwano omtsha uyakhula. Phakathi izizathu oku kubizwa ukwandiswa kweenkonzo, ukwandiswa kothungelwano wesixando enombala (pon) kunye nokuhanjiswa Metro Ethernet, ukunciphisa iindleko iimveliso ifayibha enombala, kwakunye kwimpumelelo abanye abasebenzi ekwakheni kothungelwano ezinjalo.

Iintlobo content New

Connect kwiteknoloji FTTx ngokuya kwanda ngenxa yokuba abasebenzisi lwanamhlanje Ziyanda unomdla iindidi ezintsha yekhontenti yevidiyo kunye ezikumgangatho ophezulu mifanekiso. Le iza esingundoqo ukuqaliswa kweenkqubo ifayibha-optic, uye abe nomdla ikhula kwiinkonzo yevidiyo. Ukuhambisa iziko womxhuzulane kunye multicast kwababhalisele ngamnye kufuneka ukwanda ezabelwe bandwidth, apho kuya kamsinya kakhulu kuba megabits ukuya ku-100 yesibini kwikhaya ngalinye ngenyanga.

Ukuthengiswa HDTV LCD zenziwa ngokukhawuleza ngakumbi, ebonisa ukuba umthengi ufuna iinkonzo zosasazo lweenkqubo zikamabonwakude ngaphezu koko uyakwazi ukunikeza umabonwakude analog. Ukusetyenziswa IP-TV wabonwa ziingcali ezininzi ukuba le khosi sivakalayo lweziganeko. Leyo kuphela kwendlela umsebenzisi bangakhetha transfer iifilim, kwakunye nexesha ukuzijonga. yoko kucingwa ukuba ubunzima elidityaniswe yi FTTx technology xPON iya kuba umbuzo hayi kule minyaka mihlanu izayo, kwaye kuphela isibini iminyaka. Wonke umniki-Internet ngoku uyaqonda ukuba utyalo-mali kwi ngokukhanya zimele kutyalo amashumi eminyaka ezayo, iinzuzo eziza ngaphaya iindleko amashumi amaxesha. Oku kuchaza ukuthenga esebenzayo lwelayini enombala, kwakunye nenani iiprojekthi zokulinga, kuquka kokubekela ngokukhanya ngqo izixhobo umsebenzisi.

Ziziphi iingozi?

Kwiminyaka ezayo i-Internet kwiteknoloji FTTx akayi kuba kuphela ukhetho elikwaziyo ukuqinisekisa ukubonelelwa ngendawo abanokungena broadband, kodwa nezibonelelo fibre optic has a isakhono ngokwaneleyo phezulu, ekuvumela ukuba nentembelo nokubuyiselwa zonke yotyalo. Okwangoku, uninzi umsebenzi ekuso ngenxa yotshintsho kothungelwano lomqolo kunye nemarike technology FTTx lisephantsi ukufunda, uyilo kunye nokuvavanywa. Noko ke, ngoku kukho umdla kwabasebenzisi kwiziqalelo ka-WDM kunye Umsi Optical Splitter. Ukongeza, ukukhula okulindelekileyo yintengiso emnqamlezweni umthamo enombala enkulu ezisetyenziswa izisombululo FTTx.

iintlobo lwazi bolwakhiwo lwempahla

FTTx (Rostelecom) iteknoloji iquka iintlobo ezininzi lwazi bolwakhiwo lwempahla:

- FTTN (Ifayibha ukuya esiludumbo) - ifayibha ifikelela esiludumbo yenethiwekhi;

- FTTC (Ifayibha ecaleni) - ifayibha lufika ebumelwaneni, kwikota okanye izindlu ezininzi;

- FTTB (Ifayibha kwi Building) - ifayibha ifikelela nesakhiwo;

- FTTH (Ifayibha Lwasekhaya) - ifayibha zifike yokuhlala.

Umahluko omkhulu phakathi kwabo usondele kangakanani na intambo fibre optic ngokufanelekileyo terminal yomsebenzisi. Okokuqala wabonakala izigqibo baba FTTN kunye FTTC. Isisombululo Umhla lokuqala lisetyenziselwa kuphela nje olukhawulezayo ukuphumeza mali apho kukho izibonelelo lonikezelo yobhedu, engamzondi ngokukhanya nje lutho. Iingxaki ezinxulumene isigqibo esinjalo, eyaziwayo bonke: nomgangatho ophantsi weenkonzo ezinxulumene kwiingxaki ezithile kweentambo zekopolo ukuba kwi amdaka, mda ebalulekileyo isantya kwaye inani uqhagamshelwano kuzo intambo omnye. FTTC i oluphuculiweyo uhlobo FTTN, engeyiyo yona olungabuy ezingundoqo yokugqibela. Kwimeko FTTC ukusetyenziswa kweentambo zekopolo alawulwa kuphela ngaphakathi izakhiwo, nto leyo ithetha ukuba akukho sichengeni imiba umonakalo, yaye musa nelayini-elide umgama, ixabiso naye abaqhubi zobhedu umgangatho, esetyenziswa kule meko. Kuyenzeka ngoko ukuphumeza isantya enkulu kummandla ngaphandle ifayibha. Esi sipho sisebenza xa uqhagamshela kwezobuchwepheshe FTTx pon. Le sesakhiwo ijolise basebenzi abasele ngokukhutheleyo usebenzisa iteknoloji xDSL, kwakunye abanini intambo. Ngokusebenzisa ekuphunyezweni kwalo lwezakhiwo, abanako nje ekunciphiseni iindleko kodwa nokwandisa inani labasebenzisi enxulumene, yaye bandwidth yabelwe ngamnye kubo. Olu hlobo lonxibelelwano ukuba abaqhubi Russian of Ethernet-networks ezincinane lisetyenziswe ngokufuthi, ngenxa yeendleko eliphantsi kwezisombululo zobhedu, kwakunye nemfuneko lomculi abanezakhono kakhulu nokufakelwa intambo optical.

izinto

Imibuzo izixhobo nokubekwa ukuba sicinywa icandelo woqondo lomgca wonxibelelwano lobugcisa FTTx xPON zixhomekeke yezizathu eziliqela:

- ukufumaneka kwezakhelo ezizezinye okanye ukungabikho kwalo;

- umthamo kuba-endlwini izixhobo esebenzayo;

- inani lwababhalisi enxulumene;

- enye.

Iingcali zithi kukho FTTx-terminal oluthile lwefowuni kakhulu Ukuhlelwa, encamathele kwinqanaba "x". Le sethi okucetywayo nkonzo ixhomekeke kuhlobo kunye nenani lwenjongano ezisetyenziswa kwi-terminal isixhobo, kunye nendlela yokulawula yezithuthi. Xa imfuneko yokulondoloza izibonelelo ezikhoyo kufuneka bakhokelwe iinkqubo FTTC / FTTB ukuba woqondo uplink-interface. Iinkqubo ezinjalo kufanelekile ukusebenzisa kumashishini amakhulu, izakhiwo zokuhlala kunye namaziko oshishino, apho kukho izibonelelo lobhedu ezikhoyo.

iziphumo

Olungagcinwanga lwetheknoloji FTTx ungoyena wagwetyelwa ngokoMthetho yezoqoqosho xa kuthe xi ebonakalayo abathengi ohlawulayo okanye ukwakha ezintsha, xa lombutho iingcingo ezihamab phantsi imiba nangoku kukwinqanam kuyilo lo. Kunqweneleka ukuba uthungelwano sele izicwangciso ukuze ingongoma "x" yabekwa abe kufutshane kangangoko kunokwenzeka ukuba umthengi, oko kukuthi qela. Ngexesha ukwakhiwa zezithili ezintsha ingcono ziziswe ekunene ukuya kwisakhiwo, kuya kuba ekhululekile kwaye isanda, yaye kwixesha elizayo. Esi sipho sisebenza xa uqhagamshela yi ubugcisa xpon FTTx.
