Chii chinonzi GPON Internet?

GPON Internet tekinoroji yekufambisa data iyo inokutendera kuti ubatanidze vanyoreri kuInternet nekukurumidza uye nekuvimbika. Muchikamu chino tichakuudza kuti GPON Internet chii, kuti inoshanda sei, ndezvipi zvakanakira iyo uye kuti ungaibatanidza sei.

Chii chinonzi GPON Internet?

GPON (Gigabit Passive Optical Network) is a passive optical network inoshandisa optical fiber kuendesa data pakati pehofisi yepakati (OLT) uye kunyoresa michina (ONT). GPON Internet inoreva iyo ITU-T G.984 chiyero, iyo inotsanangura maparameter uye maitiro eiyo network.

GPON internet inopa kukurumidza kwekufambisa data - inosvika 2,5 Gbit/s munzira kubva kuOLT kuenda kuONT uye inosvika 1,25 Gbit/s mune yakatarisana. Mukuwedzera, GPON Internet inotsigira marudzi akasiyana-siyana emigwagwa, akadai seInternet, telephony, terevhizheni, kutarisa kwevhidhiyo nezvimwe.

GPON Internet inoshanda sei?

GPON Internet inoshanda pamusimboti wekuparadzanisa nguva (TDM) uye wavelength division (WDM). TDM inoreva kuti data kubva kune vakasiyana-siyana vanyoreri inofambiswa pamusoro peiyo optical fiber panguva dzakasiyana, uye WDM inoreva kuti data kubva kumhando dzakasiyana dzetraffic inofambiswa pamusoro pemawavelengths akasiyana.

GPON Internet ine zvinhu zvitatu zvikuru:

• OLT (Optical Line Terminal) chishandiso chepakati chinobatanidza kune mupi weInternet uye chinogadzirisa kuendesa data pakati pe optical fibers uye kunyorera zvishandiso.
• ONT (Optical Network Terminal) mudziyo wekunyorera unobatanidza kune optical faibha uye unoshandura masaini optical kuita masaini emagetsi, uye zvakare inopa majoini ekubatanidza akasiyana midziyo senge komputa, runhare, TV nezvimwe.
• ODN (Optical Distribution Network) is optical fiber network inobatanidza OLT uye ONT. Iyo ODN inogona kusanganisira zvakasiyana-siyana passive optical zvikamu zvakadai sezvimedu, zvinobatanidza, adapters, nezvimwe.

Schematically, GPON Internet inogona kumiririrwa sezvinotevera:

Zvakanakira zveGPON

Kubatanidza kuInternet kuburikidza neGPON kune zvakati kuti zvakanaka pane mamwe matekinoroji akadai seADSL, VDSL, Ethernet kana DOCSIS. Hezvino zvimwe zvacho:

• High speed. GPON inokutendera kuti uwane kumhanya kweInternet kunosvika 2,5 Gbit/s, iyo yakakwira zvakapetwa kakati wandei kupfuura kumhanya kwemamwe matekinoroji. Izvi zvinoreva kuti unogona kuona mavhidhiyo ane tsanangudzo yepamusoro, kutamba mitambo yepamhepo, kudhawunirodha mafaera mahombe uye kushandisa zvimwe zviwanikwa zveInternet pasina kunonoka kana kukanganisa.
• Kuvimbika. GPON inoshandisa tambo yemaziso isingaenderane nekukanganiswa kwemagetsi, ngura, kupisa kana kukuvara kwemagetsi. Mukuwedzera, iyo passive optical network haina zvinhu zvinoshanda zvinogona kukundikana kana zvinoda kutsiviwa. Izvi zvinovimbisa kugadzikana uye hutano hwekukurukurirana mune chero mamiriro ezvinhu.
• Economical. GPON inokubvumira kuderedza mari yekubatanidza nekuchengetedza mambure, sezvo isingatsvaki mimwe michina, magetsi kana vashandi. Mukuwedzera, GPON inokubvumira kuti ugamuchire masevhisi akati wandei pane imwe tambo, iyo inoderedza huwandu hwewaya uye zvigadziko mufurati.
• Versatility. GPON inotsigira akasiyana maprotocol uye data transmission standard, senge IP, ATM, Ethernet, TDM nevamwe. Izvi zvinokutendera kuti ubatanidze chero zvishandiso kunetiweki uye shandisa chero masevhisi ekutaurirana, akadai seInternet, terevhizheni, runhare, vhidhiyo yekutarisa, intercom uye nevamwe.

Zvakaipa zveGPON

• Limited bandwidth. Kunyangwe GPON ichipa yakakwira Internet kumhanya, haina kuvimbiswa, asi zvinoenderana nehuwandu hwevanyoreri vakabatana kune imwe yekuona splitter. Kana paine vazhinji vanyoreri, network bandwidth ichagoverwa pakati pavo uye iyo Internet kumhanya inogona kuderera. Naizvozvo, zvakakosha kusarudza mupi anodzora nhamba yevanyoreri padivider uye inopa yakakwana bandwidth kune mumwe nemumwe munyoreri.
• Kuchengeteka kwakaderera. GPON inoshandisa tambo imwe yekuona kuendesa data kubva kune mupi kune vanonyorera vakabatana kune imwecheteyo kupatsanura. Izvi zvinoreva kuti vese vanyoreri vanogashira chiratidzo chimwe chete, chinogona kubatwa kana kugadziridzwa nevanorwisa. Naizvozvo, zvakakosha kuti usarudze mupi anoshandisa akasiyana encryption uye echokwadi nzira dzekuchengetedza data rako kubva kusingatenderwe kuwana.
• Mutengo wakakwirira. GPON inoda kuiswa kwemichina yakakosha, iyo inodhura zvikuru. Izvi zvinoshanda kune ese ari maviri OLT ari pamupi uye ONT iri mufurati yemunyoreri. Uyezve, mutengo we optical cable wakakwirawo kupfuura mutengo wemhangura tambo. Naizvozvo, miripo yekubatanidza kuGPON inogona kunge yakakwira pane yekubatanidza kune mamwe matekinoroji.

Nzira yekubatanidza GPON Internet?

Kuti ubatanidze GPON Internet, unofanirwa kuzadzisa matanho anotevera:

• Bata mushandi weInternet anopa GPON Internet service munharaunda yako uye usaine chibvumirano chekubatanidza. (Somuenzaniso Briz)
• Sarudza chirongwa chinokodzera zvaunoda uye bhajeti. Kazhinji, tariffs zvinoenderana nekumhanya, vhoriyamu uye rudzi rwetraffic, pamwe nekuwanikwa kwemamwe masevhisi akadai sefoni, terevhizheni uye mamwe.
• Gamuchira chinyoreso cheONT kubva kune wako wepaInternet, icho chinofanirwa kunge chakabatana kune optical fiber iyo mupi anozowedzera kumba kwako kana imba. An ONT inogona kuva yemukati kana yekunze, zvichienderana nerudzi rwefiber optical uye nzvimbo yekuisa.
• Batanidza kuONT midziyo yakasiyana-siyana yaunoda kushandisa kuwana Indaneti, yakadai sekombuta, foni, TV nezvimwe. Kuti uite izvi, iwe uchada tambo dzeEthernet, tambo dzenhare, coaxial tambo, kana mawireless connections.
• Gadzirisa zvigadziriso

GPON tekinoroji yemazuva ano yeInternet yekubatanidza iyo inopa kumhanya kwakanyanya, kuvimbika, kushanda nesimba uye hukuru hwekutaurirana. Inokubvumira kuti ugamuchire Internet, terevhizheni uye runhare kuburikidza netambo imwe chete yemaziso, iyo inoradzikwa zvakananga mufurati yemunyoreri. Kuti ubatanidze kuGPON, unofanirwa kusarudza mupi akakodzera, odha yekubatanidza, kumirira kuti ONT iiswe uye batanidza zvishandiso zvako. Zvakadaro, GPON inewo zvimwe zvinoipira senge bandwidth shoma, chengetedzo yakaderera uye mutengo wakakwira. Naizvozvo, unogona kufunga dzimwe nzira dzakadai seEthernet, DOCSIS kana Wi-Fi, iyo inopawo kukurumidza uye yemhando yepamusoro internet.
