OLT: Nws yog hais txog cov kab hluav taws xob kho qhov muag uas peb siv, thiab tseem yog cov khoom siv dav hlau kawg uas siv los txuas cov kab hluav taws xob kho qhov muag.
ONU: ONUhais txog ib qho chaw kho qhov muag network.ONUFeem ntau yog muab faib ua active optical network unit thiab passive optical network unit.Feem ntau, cov cuab yeej nruab nrog kev saib xyuas hauv network nrog rau optical receiver, uplink optical transmitter thiab ntau tus choj amplifiers hu ua "optical node".
OLT yog cov khoom siv hauv chaw ua haujlwm hauv EPON passive optical network system.Nws yog ntau qhov kev pabcuam muab kev pabcuam, uas tuaj yeem txhawb nqa IP cov kev pabcuam thiab cov kev pabcuam TDM ib txwm nyob rau tib lub sijhawm.Nws yog ib lub cuab yeej muab tso rau ntawm ntug ntawm lub nroog cheeb tsam network thiab ntawm qhov tawm ntawm lub zej zog nkag mus rau hauv lub network, uas tuaj yeem sib txuas cov kev pabcuam nkag mus thiab xa lawv mus rau IP network feem.
CovONU1001i uplink txuas mus rau lub hauv paus chaw ua hauj lwm los ntawm GEPON chaw nres nkoj, thiab downlink yuav muab gigabit Ethernet ports rau ib tug neeg siv los yog lwm tus neeg siv.Raws li kev daws teeb meem yav tom ntej ntawm FTTx,ONU1001i muab lub suab muaj zog, cov ntaub ntawv ceev ceev thiab cov kev pabcuam video los ntawm ib leeg-fiber GEPON.ONUmuaj nuj nqi: xaiv kom tau txais cov ntaub ntawv xa los ntawm OLT;Teb rau ntau qhov sib txawv thiab kev tswj hwm hluav taws xob xa los ntawm OLT;Thiab ua kom muaj kev hloov kho;Tus neeg siv cov ntaub ntawv Ethernet yog cached thiab xa mus rau qhov kev taw qhia uplink nyob rau hauv lub qhov rais xa xa los ntawm OLT.
