ODNs yog txhua tus ua ke ntawm cov khoom sib xws xws li cov khoom tawg, thiab tsis tas yuav muaj cov khoom siv hluav taws xob nquag ua khoom kim. Lub tshuab xa hluav taws xob (passive optical network) muaj cov kab hluav taws xob txiav tawm (OLT) nruab rau ntawm chaw tswj hwm lub chaw nres tsheb thiab teeb tsa kab hluav taws xob sib txuas (ONUs) tau teeb tsa ntawm cov neeg siv khoom. Lub Optical Distribution Network (ODN) nruab nrab ntawm OLT thiab ONU muaj cov khoom siv hluav taws xob zoo ib yam li passive optical splitters lossis couplers.
PON system feem ntau yog ua los ntawm cov kho qhov muag kab davhlau ya nyob twg (OLT: Optical Line Terminal) ntawm chaw ua haujlwm nruab nrab, kev faib khoom siv kho qhov muag (ODN: Kev Tshaj Tawm Hluav Taws Xob Hluav Taws Xob) suav nrog cov kho qhov muag, thiab cov khoom siv kho qhov muag (network network / optical network terminal) (ONU) / ONT Optical) ntawm tus neeg siv khoom kawg. Network Unit / Optical Network Terminal), qhov sib txawv yog tias ONT ncaj qha rau ntawm tus neeg siv kawg, thiab muaj lwm cov tes hauj lwm ntawm ONU thiab tus neeg siv, xws li Ethernet) thiab lub network koom nrog kev tswj hwm (EMS), uas feem ntau point-to-multipoint. Tsob ntoo topology.
Qhov zoo dua ntawm PON network yog kev tshem tawm cov khoom siv sab nraum zoov, uas txhua tus ua tiav hauv kev hloov thiab hauv tus neeg siv' s lub tsev. Ntxiv mus, kev nqis peev thaum xub thawj ntawm cov txheej txheem kev nkag mus no yog qhov me me, thiab feem ntau ntawm cov nyiaj tau muab ncua cia kom txog thaum tus neeg siv nkag mus. Nws qhov kev sib kis tau luv dua li ntawm qhov kev nkag mus ua fiber ntau, thiab qhov kev tiv thaiv tau tsawg, tab sis nws tus nqi qis, tsis tas yuav teeb tsa chav chav tshuab cais, thiab txij nkawm yooj yim. Yog li no cov qauv no tuaj yeem siv tau kev lag luam rau cov neeg siv hauv tsev.
Kev Sib Txuas Lus Optico tsim tawm ntau yam ntawm cov khoom sib xws zoo li txhua yam ntawm 1XN, 2XN PLC splitters thiab CWDM / DWDM, Mux / Demux, Fiber Pigtails, Fiber Patchcords, thiab lwm yam. Xav paub ntau ntxiv, pls pab nrhiav rau ntawm peb lub vev xaibwww.fiberopticom.com .
