PON (Passive Optical Network)
PON (Passive Optical Network). PON (passive optical network) txhais tau hais tias (hauv lub tshuab xa hluav taws xob kho qhov muag) tsis muaj cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob hluav taws xob. 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.

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, txhua lub teeb liab ua haujlwm yog ua tiav hauv cov hloov thiab cov neeg siv' s khoom siv hauv 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.
OPTICO KEV SIB TXUAS LUS (www.fiberopticom.com) tsom mus rau kev txhim kho offiber optic network sib txuas lus cov khoom kab thiab muab kev daws teeb meem zoo rau cov khoom siv sib txuas fiber ntau. Peb muab cov khoom siv fiber ntau ua ke. Txhua yam khoom lag luam lees txais cov qauv nruj me ntsis hauv kev tsim khoom thiab tshuaj ntsuam xyuas, ua kom muaj kev ua haujlwm zoo thiab ua kom cov khoom lag luam zoo, thiab kev nyab xeeb thiab kev ntseeg tau kom ntseeg tau siv lub sijhawm ntev ntawm cov khoom.
