Kodi GPON Internet ndi chiyani?

GPON Internet ndiukadaulo wotumizira ma data womwe umakulolani kuti mulumikizane ndi olembetsa pa intaneti mwachangu komanso modalirika. M'nkhaniyi tikuuzani zomwe GPON Internet ili, momwe imagwirira ntchito, ubwino wake ndi momwe mungalumikizire.

Kodi GPON Internet ndi chiyani?

GPON (Gigabit Passive Optical Network) ndi netiweki yopanda kuwala yomwe imagwiritsa ntchito ma fiber optical kutumiza deta pakati pa ofesi yapakati (OLT) ndi zida zolembetsa (ONT). GPON Internet imatanthauza muyezo wa ITU-T G.984, womwe umatanthawuza magawo ndi mawonekedwe a netiweki yotere.

Mtengo GPON pa intaneti imapereka liwiro lalikulu losamutsa deta - mpaka 2,5 Gbit/s molunjika kuchokera ku OLT kupita ku ONT ndikufika ku 1,25 Gbit/s mbali ina. Kuphatikiza apo, GPON Internet imathandizira mitundu yosiyanasiyana yamagalimoto, monga intaneti, telefoni, kanema wawayilesi, kuyang'anira makanema ndi zina.

Kodi GPON Internet imagwira ntchito bwanji?

GPON Internet imagwira ntchito pa mfundo ya magawo a nthawi (TDM) ndi magawano a kutalika kwa mafunde (WDM). TDM imatanthawuza kuti deta yochokera kwa olembetsa osiyanasiyana imafalitsidwa pamtundu umodzi wa kuwala nthawi zosiyanasiyana, ndipo WDM imatanthawuza kuti deta yochokera kumitundu yosiyanasiyana ya magalimoto imafalitsidwa pamtunda wosiyanasiyana.

GPON Internet ili ndi zinthu zitatu zazikulu:

• OLT (Optical Line Terminal) ndi chipangizo chapakati chomwe chimalumikizana ndi opereka intaneti ndikuwongolera kusamutsa kwa data pakati pa optical fibers ndi zida zolembetsa.
• ONT (Optical Network Terminal) ndi chipangizo cholembera chomwe chimagwirizanitsa ndi fiber optical ndikusintha zizindikiro za kuwala kukhala zizindikiro zamagetsi, komanso zimaperekanso zolumikizira zolumikizira zida zosiyanasiyana monga kompyuta, foni, TV ndi zina.
• ODN (Optical Distribution Network) ndi netiweki ya optical fiber yomwe imalumikiza OLT ndi ONT. ODN imatha kuphatikizira zigawo zingapo zowoneka bwino monga zogawa, zolumikizira, zosinthira, ndi zina.

Mwadongosolo, GPON Internet ikhoza kuyimiridwa motere:

Ubwino wa GPON

Kulumikizana ndi intaneti kudzera pa GPON kuli ndi maubwino angapo kuposa matekinoloje ena monga ADSL, VDSL, Efaneti kapena DOCSIS. Nazi zina mwa izo:

• Liwilo lalikulu. GPON imakupatsani mwayi wopeza liwiro la intaneti lofikira 2,5 Gbit/s, lomwe ndi lokwera kangapo kuposa liwiro laukadaulo wina. Izi zikutanthauza kuti mutha kuwona makanema apamwamba, kusewera masewera a pa intaneti, kutsitsa mafayilo akulu ndikugwiritsa ntchito zida zina zapaintaneti popanda kuchedwa kapena kusokonezedwa.
• Kudalirika. GPON imagwiritsa ntchito chingwe chowunikira chomwe sichimakhudzidwa ndi kusokonezedwa ndi ma elekitiroma, dzimbiri, kutentha kwambiri kapena kuwonongeka kwamakina. Kuphatikiza apo, passive optical network ilibe zinthu zomwe zimatha kulephera kapena kufuna kusinthidwa. Izi zimatsimikizira kukhazikika komanso kulumikizana kwabwino muzochitika zilizonse.
• Zachuma. GPON imakulolani kuti muchepetse mtengo wogwirizanitsa ndi kusunga maukonde, chifukwa sichifuna zipangizo zowonjezera, magetsi kapena ogwira ntchito. Kuphatikiza apo, GPON imakulolani kuti mulandire mauthenga angapo olankhulana pa chingwe chimodzi, chomwe chimachepetsa chiwerengero cha mawaya ndi zitsulo m'nyumbamo.
• Kusinthasintha. GPON imathandizira ma protocol osiyanasiyana ndi miyezo yotumizira deta, monga IP, ATM, Efaneti, TDM ndi ena. Izi zimakupatsani mwayi wolumikiza zida zilizonse pamaneti ndikugwiritsa ntchito njira zilizonse zoyankhulirana, monga intaneti, wailesi yakanema, telefoni, kuyang'anira makanema, intercom ndi zina.

Zoyipa za GPON

• Ma bandwidth ochepa. Ngakhale GPON imapereka liwiro lalikulu la intaneti, sizotsimikizika, koma zimatengera kuchuluka kwa olembetsa omwe alumikizidwa ndi chowotcha chimodzi chowala. Ngati pali olembetsa ambiri, bandwidth ya netiweki idzagawidwa pakati pawo ndipo liwiro la intaneti litha kuchepa. Chifukwa chake, ndikofunikira kusankha wopereka yemwe amawongolera kuchuluka kwa olembetsa pagawo lililonse ndipo amapereka bandwidth yokwanira kwa wolembetsa aliyense.
• Chitetezo chochepa. GPON imagwiritsa ntchito chingwe chimodzi chowunikira kuti itumize deta kuchokera kwa wothandizira kupita kwa olembetsa olumikizidwa ku chogawa chomwechi. Izi zikutanthauza kuti olembetsa onse amalandira chizindikiro chofanana, chomwe chingathe kulandidwa kapena kusinthidwa ndi otsutsa. Choncho, ndikofunika kusankha wothandizira amene amagwiritsa ntchito njira zosiyanasiyana zobisa ndi zovomerezeka kuti ateteze deta yanu kuti isapezeke mwachilolezo.
• Mtengo wapamwamba. GPON imafuna kukhazikitsa zida zapadera, zomwe ndizokwera mtengo kwambiri. Izi zikugwira ntchito kwa onse OLT omwe ali pamalo operekera komanso ONT omwe ali m'nyumba ya olembetsa. Komanso, mtengo wa chingwe cha optical ndiwokwera kwambiri kuposa mtengo wa chingwe chamkuwa. Chifukwa chake, mitengo yolumikizira ku GPON ikhoza kukhala yokwera kuposa yolumikizira matekinoloje ena.

Momwe mungalumikizire GPON intaneti?

Kuti mulumikizane ndi GPON Internet, muyenera kuchita izi:

• Lumikizanani ndi opereka intaneti omwe amapereka chithandizo cha intaneti cha GPON mdera lanu ndikusaina pangano la kulumikizana. (Mwachitsanzo Briz)
• Sankhani ndondomeko yomwe ikugwirizana ndi zosowa zanu ndi bajeti. Kawirikawiri, mitengo yamitengo imadalira liwiro, kuchuluka kwa magalimoto ndi mtundu wa magalimoto, komanso kupezeka kwa mautumiki owonjezera monga telephony, televizioni ndi zina.
• Landirani chipangizo cholembetsa cha ONT kuchokera kwa omwe akukuthandizani pa intaneti, chomwe chiyenera kulumikizidwa ndi fiber optical yomwe woperekayo angafikire kunyumba kwanu kapena nyumba yanu. ONT ikhoza kukhala yamkati kapena yakunja, kutengera mtundu wa fiber optical ndi malo oyika.
• Lumikizani ku ONT zida zosiyanasiyana zomwe mukufuna kugwiritsa ntchito intaneti, monga kompyuta, foni, TV ndi zina. Kuti muchite izi, mufunika zingwe za Efaneti, mizere ya foni, zingwe za coaxial, kapena ma waya opanda zingwe.

Pomaliza

GPON ndiukadaulo wamakono wolumikizira intaneti womwe umapereka liwiro lalikulu, kudalirika, kuchita bwino komanso kulumikizana konsekonse. Zimakupatsani mwayi wolandila intaneti, kanema wawayilesi ndi telefoni kudzera pa chingwe chimodzi chowunikira, chomwe chimayikidwa mwachindunji mnyumba ya olembetsa. Kuti mulumikizane ndi GPON, muyenera kusankha wothandizira woyenera, kuyitanitsa kulumikizana, dikirani kuti ONT ikhazikitsidwe ndikulumikiza zida zanu. Komabe, GPON ilinso ndi zovuta zina monga bandwidth yochepa, chitetezo chochepa komanso mtengo wapamwamba. Chifukwa chake, mutha kulingalira njira zina monga Efaneti, DOCSIS kapena Wi-Fi, zomwe zimaperekanso intaneti yachangu komanso yapamwamba.
