Ke'enehana GPON - nā'ōnaehana hou o ka'imi loea

'O GPON-'enehana i kēia manawa ka'oi aku o nā manawa hou, pono a me ka'ōlelo ho'olaha i loko o ka'ohana nui loa o nā pūnaewele fiber-optic. Ma muli o nā kūlana Europa o nā makahiki i hala aku nei, ho'olako'ia i nā mea kelepona telepika a me nā mea'eneke pūnaewele me nā kōkua kūpono i ka māhele o ka wikiwiki nui i ka Pūnaewele puni honua, kahi hō'ailona ho'omaha a me ka maika'i o ka telephoto. GPON-enehana no hoi ua hoakaka loa nui makauliʻi o ka'ōnohi puluniu ma o ka laau topology pukapuka kuhikuhipuʻuone, a ua loaʻa kiʻekiʻe pono ma OE ai manamana ai hehee wale. Akā,'oi aku paha ka maika'i nui o kēia'ike hou o ka'enehana i loko o ka holo māmā "mile mua".

Kāko'o'o GPON-kekōnae i ka hana hana ho'onui pinepine'ana i kēia manawa, e hiki ai ke ho'onui i ka'enehana pūnaewele me ka ho'oulu'ana i kā lākou hana hana ho'oili. A'o ka lā'au kumu lā'au e hāmama ana i nā mea āpau e hiki ai ke ho'oikaika i ka lawelawe'ana i nā lawelawe o nā mea lawelawe. I kēia kumuhana, he loiloi loiloi loiloi kūpono ka'ikepili GPON, e hā'awi ana i ka'ike o ke ka'a no nā lawelawe like'ole: SDH, Ethernet, ATM, etc.

No laila, he nui nā kūlana o nā pūnaewele fiber-optic a me kekahi o ko lākou mau mana kūikawā e ho'oholo i nā mea maika'i o kēia'enehana ma luna o nā mea'ē a'e o nā'enehana telepili, ke'ole ka pili'ana o ka "mile mua". 'O kēia ke kumu o ka ho'olaha nui'ana o kēia hana hou i ka hana'ana i nā pūnaewele multiservice nui o ka fiber-optic. He aha ka ka GPON-enehana, a me ka mea o kona o Mānoa?

I loko o ia iho, he ma'alahi, e like me nā mea hewa'ole. 'O ka kikowaena waena o ka mea hā'awi, e hā'awi ana i kahi hilina'i hope'ana o ka hapalua, ua ho'ohui'ia i nā helu o nā mea kākau ma kahi pūnaewele puka o ka hana hale. I kēia hihia, ua ho'okumu'ia nā kōwae waena kūikawā, a ua ho'onohonoho'ia i loko o kēlā me kēia pu'upu'u pinepine pipili (splitters) o ke'ano kelepona. 'O kā lākou'ike'ana,'a'ole lākou i nele i ka'ai a i'ole i ka lawelawe.

'O GPON-lako, ma waho a'e o ka po'e mokuahi, kahi pūnaewele hō'ano pūnaewele-pūnaewele pūnaewele a me nā palena hope pūnaewele. A me kekahi anuu hiki ke hoʻouna i ka 'ike e like me ka helu o ka mea kūʻai mea, e leie aku oe e hoʻohui ia i ka Bedroom ka mana a me ka māmā transceiver Lako. Hiki i ka hui pū'ana o nā mea hana hou i kēia manawa ke hiki i ka manawa pōkole a me ka loa'a'ole o nā kumukū'ai hou no ka ho'okomo'ana i nā pūnaewele fiber-optic passive a ho'ololi i ka ho'olālā kelepona.

'O ka mea'olu'olu,'a'ohe mea'oko'a o nā network fiber-optic passive i nā lā o nā pūnaewele o kēia manawa. 'O ke kūkulu'ana o kēia'enehana'ike'ike'ikepili i ho'omaka i loko o nā kanawalukūmāwalu o ka hohonu o nā laboratories British Telecom. I kekahi mau makahiki ma hope iho o ka ho'omaka'ana o ka ho'olālā'ana, ua ho'okō'ia nā ho'okolohua ho'ā'o mua, a ma laila kahi i hui pū'ia ai nā pūlepa elele Pākani nui kaulana. I ka wā e hiki mai ana, ua hele aku kēia'enehana i nā manawa he nui o ka ho'omaika'i a me ka ho'ololi'ana. Ka mua OE pukapuka o kēia 'ano i ka ' auhau o ka 155 Mbit / mau. Eia nō na'e, no kēlā mau manawa ua lawa. A i kēia manawa wale nō, i pili i ka holomua o ka Internet a me ke kelepona telepili, ua ho'opili'ia kēia'enehana i ka noi.
