He aha ka GPON Internet?

ʻO GPON Internet kahi ʻenehana hoʻoili ʻikepili optical e hiki ai iā ʻoe ke hoʻopili i nā mea kākau inoa i ka Pūnaewele me ka wikiwiki a me ka hilinaʻi. Ma kēia ʻatikala e haʻi mākou iā ʻoe i ke ʻano o ka Pūnaewele GPON, pehea e hana ai, he aha nā pōmaikaʻi a pehea e hoʻopili ai.

He aha ka GPON Internet?

ʻO GPON (Gigabit Passive Optical Network) kahi pūnaewele ʻike passive e hoʻohana ana i nā fiber optical e hoʻouna i ka ʻikepili ma waena o ke keʻena kikowaena (OLT) a me nā lako mea kākau (ONT). ʻO ka pūnaewele GPON e pili ana i ka maʻamau ITU-T G.984, e wehewehe ana i nā palena a me nā hiʻohiʻona o ia pūnaewele.

pūnaewele GPON hāʻawi i nā wikiwiki hoʻoili ʻikepili kiʻekiʻe - a hiki i 2,5 Gbit/s ma ke kuhikuhi mai OLT a i ONT a hiki i 1,25 Gbit/s ma ka ʻaoʻao ʻē aʻe. Eia kekahi, kākoʻo ʻo GPON Internet i nā ʻano kaʻa like ʻole, e like me ka Pūnaewele, kelepona, televise, nānā wikiō a me nā mea ʻē aʻe.

Pehea e hana ai ka pūnaewele GPON?

Hoʻohana ʻo GPON Internet ma ke kumu o ka mahele manawa (TDM) a me ka mahele hawewe (WDM). ʻO TDM ke ʻano o ka lawe ʻia ʻana o ka ʻikepili mai nā mea kākau like ʻole ma luna o ka fiber optical hoʻokahi i nā manawa like ʻole, a ʻo WDM ke ʻano o ka lawe ʻia ʻana o ka ʻikepili mai nā ʻano kaʻa like ʻole ma luna o nā lōʻihi nalu like ʻole.

ʻO ka pūnaewele GPON he ʻekolu mau mea nui:

• ʻO OLT (Optical Line Terminal) kahi mea kikowaena e hoʻopili ai i ka mea hoʻolako pūnaewele a mālama i ka hoʻoili ʻikepili ma waena o nā fiber optical a me nā mea kākau inoa.
• ʻO ONT (Optical Network Terminal) kahi mea kākau inoa e hoʻopili ai i kahi fiber optical a hoʻololi i nā hōʻailona optical i nā hōʻailona uila, a hāʻawi pū i nā mea hoʻohui no ka hoʻopili ʻana i nā mea like ʻole e like me ke kamepiula, kelepona, TV a me nā mea ʻē aʻe.
• ʻO ODN (Optical Distribution Network) kahi pūnaewele fiber optical e hoʻopili ai iā OLT a me ONT. Hiki i kahi ODN ke hoʻokomo i nā ʻāpana optical passive e like me nā splitters, connectors, adapters, a me nā mea ʻē aʻe.

Schematically, hiki ke hōʻike ʻia ka Pūnaewele GPON penei:

Nā pōmaikaʻi o GPON

ʻO ka hoʻohui ʻana i ka Pūnaewele ma o GPON he mau mea maikaʻi ma mua o nā ʻenehana ʻē aʻe e like me ADSL, VDSL, Ethernet a i ʻole DOCSIS. Eia kekahi o lākou:

• ʻO ka wikiwiki kiʻekiʻe. ʻAe ʻo GPON iā ʻoe e kiʻi i ka wikiwiki o ka Pūnaewele a hiki i 2,5 Gbit/s, ʻoi aku ka nui o nā manawa ma mua o ka wikiwiki o nā ʻenehana ʻē aʻe. ʻO ia ke ʻano hiki iā ʻoe ke nānā i nā wikiō wehewehe kiʻekiʻe, pāʻani i nā pāʻani pūnaewele, hoʻoiho i nā faila nui a hoʻohana i nā kumuwaiwai pūnaewele ʻē aʻe me ka ʻole o ka lag a keakea.
• Paʻa pono. Hoʻohana ʻo GPON i ke kelepona optical ʻaʻole i pili i ka interference electromagnetic, corrosion, overheating a i ʻole ka pōʻino mechanical. Eia kekahi, ʻaʻohe mea hana o ka passive optical network i hiki ke hāʻule a koi paha i kahi pani. Mālama kēia i ka paʻa a me ka maikaʻi o ke kamaʻilio ʻana i nā kūlana.
• Hoʻokele waiwai. ʻAe ʻo GPON iā ʻoe e hōʻemi i ke kumukūʻai o ka hoʻopili ʻana a me ka mālama ʻana i ka pūnaewele, no ka mea ʻaʻole ia e koi i nā mea hana hou, uila a limahana paha. Eia kekahi, ʻae ʻo GPON iā ʻoe e loaʻa i nā lawelawe kamaʻilio ma luna o hoʻokahi kelepona, e hōʻemi ana i ka helu o nā uea a me nā kumu i loko o ke keʻena.
• ʻAno ʻano. Kākoʻo ʻo GPON i nā protocol like ʻole a me nā kūlana hoʻoili ʻikepili, e like me IP, ATM, Ethernet, TDM a me nā mea ʻē aʻe. Hāʻawi kēia iā ʻoe e hoʻopili i nā mea hana i ka pūnaewele a hoʻohana i nā lawelawe kamaʻilio, e like me ka Internet, televise, telephony, video surveillance, intercom a me nā mea ʻē aʻe.

Nā hemahema o GPON

• ʻO ka bandwidth palena. ʻOiai hāʻawi ʻo GPON i ka wikiwiki pūnaewele kiʻekiʻe, ʻaʻole ia e hōʻoiaʻiʻo ʻia, akā pili i ka helu o nā mea kākau inoa i hoʻopili ʻia i hoʻokahi splitter optical. Inā nui nā mea kākau inoa, e māhele ʻia ka bandwidth pūnaewele ma waena o lākou a hiki ke emi ka wikiwiki o ka pūnaewele. No laila, he mea nui e koho i kahi mea hoʻolako e hoʻomalu i ka helu o nā mea kākau no kēlā me kēia māhele a hāʻawi i ka bandwidth kūpono no kēlā me kēia mea kākau inoa.
• Palekana haʻahaʻa. Hoʻohana ʻo GPON i hoʻokahi uwea optical e hoʻouna i ka ʻikepili mai ka mea hāʻawi aku i nā mea kākau inoa i pili i ka splitter like. ʻO ia ke ʻano o ka loaʻa ʻana o nā mea kākau inoa i ka hōʻailona like, hiki ke hoʻopaʻa ʻia a hoʻololi ʻia e nā mea hoʻouka. No laila, he mea nui e koho i kahi mea hoʻolako e hoʻohana ana i nā ʻano hoʻopunipuni a me nā ʻano hōʻoia e pale i kāu ʻikepili mai ka ʻae ʻole ʻia.
• Kumukuai kiekie. Pono ʻo GPON i ka hoʻokomo ʻana i nā mea hana kūikawā, ʻoi aku ka pipiʻi. Pili kēia i ka OLT i loaʻa ma ka mea hoʻolako a me ka ONT i loko o ke keʻena o ka mea kākau inoa. Eia kekahi, ʻoi aku ka kiʻekiʻe o ke kumukūʻai o ke kelepona optical ma mua o ke kumukūʻai o ke kaula keleawe. No laila, ʻoi aku ka kiʻekiʻe o ka uku no ka hoʻopili ʻana iā GPON ma mua o ka hoʻopili ʻana i nā ʻenehana ʻē aʻe.

Pehea e hoʻopili ai i ka pūnaewele GPON?

No ka hoʻopili ʻana i ka Pūnaewele GPON, pono ʻoe e hoʻopau i kēia mau hana:

• E hoʻokaʻaʻike i kahi mea hoʻolako pūnaewele e hāʻawi ana i ka lawelawe pūnaewele GPON ma kou wahi a kau inoa i kahi ʻaelike pili. (No ka laʻana ʻo Briz)
• E koho i kahi hoʻolālā e kūpono i kāu mau pono a me kāu kālā. ʻO ka maʻamau, pili nā kumukūʻai i ka wikiwiki, ka nui a me ke ʻano o ke kaʻa, a me ka loaʻa ʻana o nā lawelawe hou e like me ke kelepona, televise a me nā mea ʻē aʻe.
• E kiʻi i kahi mea kākau inoa ONT mai kāu mea hoʻolako pūnaewele, pono e hoʻopili ʻia i ka fiber optical e hoʻonui ʻia e ka mea hāʻawi i kou home a hale paha. Hiki i ka ONT ke lilo i loko a i waho paha, ma muli o ke ʻano o ka fiber optical a me kahi hoʻonohonoho.
• Hoʻohui i nā polokalamu like ʻole ONT āu e makemake ai e hoʻohana no ke komo ʻana i ka Pūnaewele, e like me ke kamepiula, kelepona, TV a me nā mea ʻē aʻe. No ka hana ʻana i kēia, pono ʻoe i nā uwea Ethernet, nā laina kelepona, nā uwea coaxial, a i ʻole nā ​​​​pili uila.
• Hoʻopilikino i nā hoʻonohonoho

 

 

hopena

ʻO GPON kahi ʻenehana pili pūnaewele hou e hāʻawi ana i ka wikiwiki kiʻekiʻe, hilinaʻi, kūpono a me ke ao holoʻokoʻa o ke kamaʻilio. Hāʻawi ia iā ʻoe e loaʻa ka Internet, televise a me ke kelepona ma o hoʻokahi kelepona optical, i waiho pololei ʻia i loko o ke keʻena o ka mea kākau inoa. No ka hoʻopili ʻana iā GPON, pono ʻoe e koho i kahi mea hoʻolako kūpono, e kauoha i kahi pilina, e kali i ka ONT e hoʻokomo a hoʻohui i kāu mau polokalamu. Eia naʻe, loaʻa iā GPON kekahi mau hemahema e like me ka bandwidth palena, palekana haʻahaʻa a me ke kumukūʻai kiʻekiʻe. No laila, hiki iā ʻoe ke noʻonoʻo i nā koho ʻē aʻe e like me Ethernet, DOCSIS a i ʻole Wi-Fi, e hāʻawi pū ana i ka pūnaewele wikiwiki a kiʻekiʻe.
