Cffiberlink muaj kev faib khoom nplua nuj thiab kis tau tus mob, suav nrog qib kev tswj hwm kev hloov pauv rau 5G optical fiber ntau cov cuab yeej sib txuas lus, POE ntse, network keyboards, thiab SFP optical modules. Ntawm lawv, qhov hloov khoom lag luam ib leeg tau pib ntau dua 100 qauv.
Muaj ntau ntau cov qauv, thiab nws yog ib qho inevitable uas yuav muaj sij hawm thaum koj dazzling.
Niaj hnub no, peb yuav systematically txheeb tawm txoj kev xaiv ntawm keyboards rau koj.
01【Xaiv Gigabit lossis 100M】
Nyob rau hauv lub network ntawm kev soj ntsuam video, ib tug loj npaum li cas ntawm cov ntaub ntawv video txuas ntxiv yuav tsum tau xa mus, uas yuav tsum tau hloov mus kom muaj peev xwm stably xa mus rau cov ntaub ntawv. Ntau lub koob yees duab txuas nrog rau qhov hloov, qhov ntau dua cov ntaub ntawv ntws los ntawm kev hloov. Peb tuaj yeem xav txog cov cai ntws raws li cov dej ntws, thiab cov keyboards yog cov dej txuag dej ib qho los ntawm ib qho. Thaum cov dej ntws ntws ntau tshaj qhov load, lub pas dej yuav tawg. Ib yam li ntawd, yog tias tus nqi ntawm cov ntaub ntawv xa los ntawm lub koob yees duab hauv qab qhov hloov pauv ntau tshaj qhov muaj peev xwm xa tawm ntawm qhov chaw nres nkoj, nws tseem yuav ua rau qhov chaw nres nkoj pov tseg ntau cov ntaub ntawv thiab ua rau muaj teeb meem.
Piv txwv li, 100M hloov xa mus rau cov ntaub ntawv ntim ntau tshaj 100M yuav ua rau cov pob ntawv poob ntau, uas ua rau muaj qhov tshwm sim ntawm qhov muag plooj thiab daig.
Yog li, pes tsawg lub koob yees duab yuav tsum tau txuas nrog lub gigabit hloov?
Muaj tus qauv, saib tus nqi ntawm cov ntaub ntawv xa mus los ntawm qhov chaw nres nkoj sab saud ntawm lub koob yees duab: yog tias tus nqi ntawm cov ntaub ntawv xa los ntawm qhov chaw nres nkoj sab saud ntau dua 70M, xaiv qhov chaw nres nkoj gigabit, uas yog, xaiv lub gigabit hloov lossis gigabit. uplink hloov
Nov yog ib qho kev suav ceev thiab xaiv txoj kev:
Bandwidth tus nqi = (sub-kwj + lub ntsiab kwj) * tus naj npawb ntawm cov channel * 1.2
①Bandwidth tus nqi> 70M, siv Gigabit
②Bandwidth tus nqi <70M, siv 100M
Piv txwv li, yog tias muaj qhov hloov pauv txuas nrog 20 H.264 200W koob yees duab (4 + 1M), ces raws li qhov kev suav no, tus nqi xa tawm ntawm qhov chaw nres nkoj uplink yog (4 + 1) * 20 * 1.2 = 120M> 70M, Nyob rau hauv cov ntaub ntawv no, ib tug gigabit hloov yuav tsum tau siv. Hauv qee qhov xwm txheej, tsuas yog ib qho chaw nres nkoj ntawm qhov hloov pauv yuav tsum yog gigabit, tab sis yog tias lub kaw lus tsis tuaj yeem ua kom zoo dua thiab cov tsheb tuaj yeem sib npaug, ces yuav tsum tau hloov gigabit lossis gigabit uplink hloov.
Nqe Lus Nug 1: Cov txheej txheem kev suav ntawm cov kwj dej yog qhov tseeb heev, tab sis vim li cas thiaj muab nws los ntawm 1.2?
Vim hais tias raws li lub hauv paus ntsiab lus ntawm kev sib txuas lus network, encapsulation ntawm cov ntaub ntawv packets kuj ua raws li TCP / IP raws tu qauv, thiab cov ntaub ntawv ib feem yuav tsum tau cim nrog lub header teb ntawm txhua tus txheej txheem raws tu qauv kom kis tau zoo, yog li lub header kuj yuav nyob rau hauv ib tug. qee feem pua ntawm cov nyiaj siv ua haujlwm.
Lub koob yees duab 4M ntsis tus nqi, 2M ntsis tus nqi, thiab lwm yam peb feem ntau tham txog qhov tiag xa mus rau qhov loj ntawm cov ntaub ntawv ib feem. Raws li kev faib ua feem ntawm cov ntaub ntawv kev sib txuas lus, cov nyiaj siv ua haujlwm ntawm header suav txog li 20%, yog li cov qauv yuav tsum tau muab faib ua 1.2.
Yog li, pes tsawg lub koob yees duab yuav tsum tau txuas nrog lub gigabit hloov?
Muaj tus qauv, saib tus nqi ntawm cov ntaub ntawv xa mus los ntawm qhov chaw nres nkoj sab saud ntawm lub koob yees duab: yog tias tus nqi ntawm cov ntaub ntawv xa los ntawm qhov chaw nres nkoj sab saud ntau dua 70M, xaiv qhov chaw nres nkoj gigabit, uas yog, xaiv lub gigabit hloov lossis gigabit. uplink hloov.
