GPON technology - tshiab horizons ntawm telecommunications

Lub GPON-technology yog tam sim no lub feem ntau niaj hnub, npaum thiab rau pem hauv ntej-tom nrhiav nyob rau hauv ib tug ncaj sab tsev neeg ntawm passive fiber-optic tes hauj lwm. Raws li cov tam sim no nyob rau hauv xyoo tsis ntev los, European qauv, nws muab cable TV tswv thiab Internet neeg muab kev pab rau kev daws teeb meem nyob rau hauv lub teb ntawm high-ceev nkag tau mus rau lub ntiaj teb dav Web, ruaj khov lub teeb liab thiab ib tug exceptional zoo ntawm TV dluab. GPON-technology kuj muab tseem ceeb heev nyiaj ntawm tus kho qhov muag fiber los ntawm ib tsob ntoo topology network architecture, thiab siab muaj kev cia siab yog tiav los ntawm passive branching ntsiab. Tab sis tej zaum qhov tseem ceeb kom zoo dua ntawm lub telecommunication nrhav yog ib tug high-ceev "mais kawg".

GPON-technology txhawb niaj hnub txheej txheem ntawm wavelength division Multiplexing, uas tso cai rau ho kom network muaj peev xwm tsis muaj kho kom zoo dua lawv cable infrastructure. Ib tug ntoo topology muaj cib fim rau saj zawg zog tswj Bandwidth neeg cov kev pab cuam. Nyob rau tib lub GPON technology muaj ib tug txaus siab cov ntaub ntawv tus nqi uas muab transparency kev thauj rau ib tug ntau yam ntawm cov kev pab cuam: SDH, Ethernet, ATM, etc.

Yog li, tus heev heev zoo ntawm passive fiber-optic tes hauj lwm thiab ib tug xov tooj ntawm txawv nta yog txiav txim los ntawm lub zoo ntawm no technology dua lwm telecommunication architectures, tshwj xeeb tshaj yog nyob rau hauv kev xav txog high-ceev "mais kawg". Qhov no yog vim lub ceev ceev kis ntawm lub innovation nyob rau hauv kev tsim kho ntawm high-ceev fiber-optic lub nroog multiservice tes hauj lwm. Yuav ua li cas yog lub GPON-technology, thiab dab tsi yog nws essence?

Los ntawm nws tus kheej, nws yog ib yam yooj yim, xws li tag nrho cov ci ntsa iab. Lub hauv paus mob nkees heev, muab high-ceev caj qaum kev twb kev txuas cov ntsiab lus kev cob cog rua rau lub passive kho qhov muag neeg yuav network ntawm ib tsob ntoo architecture. Qhov no tsim ib tug tshwj xeeb intermediate ntshav uas host lub compact passive splitters (splitters) kho qhov muag hom. Lawv passivity txhais tau tias lawv kiag li tsis tas yuav khoom noj khoom haus los yog kev pab cuam.

Lub GPON-khoom, splitters, muaj xws li multi-kev pab cuam kho vajtse thiab software chaw nres tsheb platform thiab cov neeg siv terminals. Thiab ib tug platform yuav kis ntaub ntawv xws tooj ntawm neeg pab kiag li lawm, uas tso cai rau koj mus cuag nws rau cov nyiaj txiag hwj chim thiab ceev transceiver kho vajtse. Lub totality ntawm cov niaj hnub khoom tso cai rau koj kom sai thiab nqi-zoo deploy passive fiber-optic network, thiab txawj tej yam ntxiv cov cable architecture.

Yuav ua li cas yog nthuav yog hais tias lub passive kho qhov muag fiber tes hauj lwm tsis muaj cov invention ntawm tam sim no hnub systems. Cov kev loj hlob ntawm no kis tau tus mob technology pib nyob rau hauv lub eighties, nyob rau hauv lub depths ntawm British Telecom no-piv. Ib tug ob peb xyoos tom qab tus thawj xeem tej kev txom nyem tau nqa tawm tom qab pib ntawm txoj kev loj hlob, uas twb tau mus kawm los ntawm ntau yam zoo-paub nyob sab Europe TV. Nyob rau hauv lub neej yav tom ntej, qhov no technology twb dhau ntau theem ntawm kev txhim kho thiab Modernization. Tus thawj passive network ntawm no hom muaj ib tug muaj peev xwm ntawm 155 Mbit / s. Txawm li cas los, thaum lub sij hawm qhov no yog txaus. Thiab xwb tam sim no, vim yog lub ceev ceev kawm tau ntawm cov Internet thiab cov TV, cov technology yog muaj pov thawj los ua ib tug tiag tiag nrov.
