GPON michina - itsva horizons kuti foni

The GPON-zvemichina pari kupfuura ano, vakarongeka uye ramangwana mumhuri nokururamisira paupamhi pamusoro pusa faibha-optic network. Inobva kuitika mumakore achangodarika, mitemo European, rine waya terevhizheni dzaishandisa uye Internet basa rubatsiro kune zvinobudirira zvinogadzirisa mumunda mukuru-nokukurumidza kuwana World Wide Web, yakatsiga chiratidzo uye rakasiyana unhu terevhizheni mifananidzo. GPON-Michina rinopawo chaizvo zvinokosha mumari Manyiminya faibha kuburikidza muti topology nomumbure mapurani, uye yakakwirira kuvimbika zvinoitwa pusa branching zvinhu. Asi zvichida mukuru mukana telecommunication zvakagadzirwa chinhu mukuru-nokukurumidza "okupedzisira maira '.

GPON-zvemichina anotsigira ano unyanzvi kuti wavelength weboka multiplexing, izvo zvinoita kuti yekudyidzana kuwedzera zvakarukwa vanokwanisa pasina upgrading kwavo waya kwezvivako. A muti topology inopa mikana zvikuru kusanduka utariri Bandwidth yeGmail.END_STRONG mabasa. Panguva GPON zvemichina ane zvakakwana yakakwirira date mwero kuti anopa zvinhu pachena pakufamba kwenguva dzakasiyana-siyana mabasa: SDH, Ethernet, ATM, etc.

Nokudaro, vakawanda zvakanakira pusa faibha-optic network uye vanoverengeka yakasiyana zvinhu takatsunga ne zvakanakira ruzivo urwu pamusoro dzimwe telecommunication architectures, kunyanya panyaya mukuru-nokukurumidza "okupedzisira maira '. Izvi imhaka kukurumidza kuparadzirwa utsanzi pakuvaka mukuru-nokukurumidza faibha-optic guta multiservice network. Chii GPON-ano, uye chii chiri chaizvo?

By pacharo, zviri nyore, sezvinoita zvose penya. The nechepakati Provider raiva pedyo nebundu, ichipa mukuru-nokukurumidza muzongoza kubatana pfungwa chokuita kuti pusa Manyiminya rinotengeswa nevaridzi richikurukura muti mapurani. Izvi zvinoitawo kuti inokosha zvenguva nodes kuti chehondo tsindirana pusa splitters (splitters) Manyiminya mhando. passivity kwavo kunoreva kuti havana zvachose vasingadi zvokudya kana basa.

The GPON-midziyo, splitters, rinosanganisira multi-basa Hardware uye Software chiteshi chikuva uye User zviteshi. Uye mumwe kuchikuva anogona nekufambisa mashoko akadaro nhamba rinotengeswa nevaridzi mano, izvo zvinoita kuti kubatanidza nayo bhajeti simba uye nokukurumidza transceiver Hardware. The raora yazvino midziyo unokubvumira nokukurumidza uye mutengo-zvinobudirira dhipuroya pusa faibha-optic network, uye ndiwedzere kuti waya mapurani.

Chii kunakidza ndechokuti pusa Manyiminya faibha network havasi nokugadzirwa kwakaitwa nhasi enyika. Kukura ichi Kupfuudzwa michina kwakatanga eighties, makadzika British Telecom Labs. Kwapera makore mashomanana okutanga bvunzo miedzo rwaiitwa pashure kutanga kukura, yakanga wakapindwa zhinji terevhizheni vanozivikanwa European. Mune ramangwana, ruzivo urwu kwapfuura mumatanho dzakawanda nani uye mazuvaano. Yokutanga pusa richikurukura ichi mhando aiva kukwanisa kuti 155 Mbit / s. Zvisinei, panguva ino yakanga yakakwana. Uye chete ikozvino, nokuda kufambira mberi Indaneti uye digitaalinen TV, mabikirwo kunoratidzwa kuva zvechokwadi mukurumbira.
