ONU: tag nrho lub npe Optical Network Unit, optical network unit, feem ntau hu uaONU, siv PON passive optical fiber nkag technology, kis nruab nrab rau optical fiber, yog ib tug loj-scale mainstream nkag hom ntawm lub ntiaj teb no telecom tswv, nrog rau qhov zoo ntawm tus nqi qis, siab bandwidth thiab tsis tshua muaj latency, tsis muaj hwj chim txij nkawm yuav tsum tau, thiab yooj yim tswj.
EOC: tag nrho lub npe Ethernet Tshaj Cable, Ethernet cov ntaub ntawv los ntawm Coaxial cable kis tau tus mob, Raws li cable TV coaxial cable siv Ethernet raws tu qauv Access technology, lub siab tshaj plaws bidirectional bandwidth ntawm 100M, xov tooj cua thiab TV siv hom. Nyob rau theem pib, cov xov tooj cua thiab TV tau txais ib txoj hauv kev xa cov neeg siv kev pabcuam kom tau txais lawv dhau los, thiab EOC thev naus laus zis tau hloov pauv hauv ob txoj kev hloov pauv ntawm cable TV network, siv EPON + EOC davhlau ya nyob twg network thiab txuas nrog tus neeg siv. EOC los ntawm coaxial cable. Vim muaj kev txwv ntawm bandwidth thiab tus nqi thiab lwm yam, tam sim no cov neeg ua haujlwm hauv xov tooj cua thiab TV tau maj mam siv PON thev naus laus zis rau kev sib kis, xws li Shenzhen Topway tau xaim fiber ntau hauv lub tsev tshiab.
CM: lub npe tag nrho Cable Modem, cable modem, feem ntau hu ua coaxialonu, los ntawm cov cable TV coaxial cable rau cov ntaub ntawv nkag mus rau cov khoom siv, xov tooj cua thiab TV nkag hom, lub hauv ntej-kawg siv CMTS tswj qhov system. Cable Modem converts uplink digital signal (IP) rau analog xov tooj cua zaus teeb liab (RF) rau kev sib kis, thiab downlink converts analog xov tooj cua zaus teeb liab (RF) rau hauv cov teeb liab (IP) rau kev txais tos. Cable Modem feem ntau yog siv los ntawm xov tooj cua thiab TV tswv (qhov siab tshaj plaws bandwidth ntawm Shenzhen Topway CM nkag mus yog 100M). Vim muaj kev txwv ntawm kev siv bandwidth thiab tus nqi, qhov kev nkag mus rau hom no kuj raug txiav tawm.
ADSL: tag nrho lub npe Asymmetric Digital Subscriber Kab, asymmetric cov neeg siv kab, feem ntau hu ua hluav taws xobonu, cov neeg ua haujlwm thaum ntxov tau siv hom kev nkag mus, siv cov cuab yeej siv hluav taws xob sib faib, kev tshaj tawm xov xwm rau cov xov tooj, cov teeb liab tsis tshua muaj hluav taws xob sib kis thiab cov teeb liab siab sib cais, yog cov ntaub ntawv ceev ceev ntawm cov xov tooj sib txuas. Tsis muaj peev xwm ua tau raws li cov kev xav tau ntawm kev siv hluav taws xob ceev thiab cov nqi siab, nws maj mam hloov los ntawm PON thev naus laus zis.
Shenzhen HDV Photoelectron Technology Ltd. yog tus kws tshaj lijONU/ ONT cov chaw tsim khoom tseem yog kev sib txuas lus ntseONUmodule chaw tsim khoom, peb lub tuam txhab tam sim no muag ntau yam khoom siv sib txuas lus sab sauv thiab qis, xws li, Fiber Media Converter, Ethernethloov, OLT khoom,ONUkhoom siv thiab lwm yam. Yog tias koj xav paub ntau ntxiv txog kev sib txuas lus thev naus laus zis, txais tos hu rau peb txhua lub sijhawm.
