Cov channel txuas cov cuab yeej sib txuas lus ntawm qhov kawg xa thiab qhov kawg tau txais, thiab nws txoj haujlwm yog xa cov teeb liab los ntawm qhov xa mus rau qhov kawg tau txais. Raws li cov xov xwm sib txawv, cov channel tuaj yeem muab faib ua ob pawg: wireless channel thiab wired channels. Wireless channels siv kev nthuav tawm ntawm electromagnetic nthwv dej hauv qhov chaw kom xa cov teeb liab, thaum cov xov tooj cua siv cov khoom siv dag zog los xa hluav taws xob lossis kho qhov muag teeb liab. Cov xov tooj ruaj khov siv ib txwm siv cov xov tooj cua (xov tooj kab) ua qhov nruab nrab ntawm kev sib kis, thiab xov tooj cua tshaj tawm yog siv wireless channel los xa xov tooj cua. Lub teeb kuj yog ib hom electromagnetic yoj, nws tuaj yeem mus hauv qhov chaw, tab sis kuj tuaj yeem kis tau rau hauv nruab nrab ntawm lub teeb. Yog li ntawd, kev faib tawm ntawm ob pawg ntawm cov channel saum toj no kuj tseem siv tau rau cov teeb liab kho qhov muag. Qhov nruab nrab siv los coj lub teeb yog yoj taw qhia thiab fiber ntau optical. Optical fiber ntau yog siv dav dav hauv kev sib txuas lus hauv xov tooj cua.
Raws li cov yam ntxwv sib txawv, cov channel tuaj yeem muab faib ua qhov tsis tu ncua channel thiab random parameter channel. Cov yam ntxwv ntawm qhov tsis tu ncua parametric channel tsis hloov nrog lub sijhawm, thaum cov yam ntxwv ntawm random parametric channel hloov nrog lub sijhawm.
Hauv cov qauv kev sib txuas lus, nws kuj tau hais tias muaj suab nrov hauv cov channel, uas muaj qhov cuam tshuam tseem ceeb ntawm cov teeb liab kis tau tus mob, yog li nws feem ntau suav tias yog kev cuam tshuam. Cov yam ntxwv tsis zoo ntawm cov channel nws tus kheej tuaj yeem suav tias yog hom kev cuam tshuam tsis zoo. Hauv tshooj no, peb yuav tsom mus rau cov yam ntxwv ntawm kev sib kis ntawm channel thiab suab nrov, thiab lawv cov teebmeem ntawm cov teeb liab kis tau tus mob.
Nov yog Shenzhen HDV phoeletron Technology Ltd. coj los qhia koj txog "keeb kwm channel" tsab xov xwm, vam tias yuav pab tau koj, thiab Shenzhen HDV phoeletron Technology Ltd. yog cov chaw tsim khoom tshwj xeeb ntawm kev sib txuas lus cov khoom lag luam, lub tuam txhab cov khoom siv kev sib txuas lus nrov muaj ntau dua:ONUseries, transceiver series,OLTseries, tab sis kuj tsim cov module series, xws li: Kev sib txuas lus optical module, optical kev sib txuas lus module, network optical module, kev sib txuas lus kho qhov muag module, optical fiber module, Ethernet optical fiber module, thiab lwm yam., tuaj yeem muab cov kev pabcuam zoo rau cov neeg siv sib txawv. ' xav tau, txais tos koj tuaj xyuas.
