POE Injector Guide: Yuav Ua Li Cas Rau Cov Khoom Siv Hluav Taws Xob
Feb 11, 2026| 48 units ntawm 802.3bt koob yees duab: 24 ua haujlwm ib txwm ua, 24 rov ua dua offline.
Lub hli tas los tus neeg siv khoom hauv Dongguan tau hu nrog qhov teeb meem no. Lawv cov neeg koom ua ke twb tau siv ob hnub sib pauv cov tshuaj txhaj tshuaj, hloov cov kab hluav taws xob, txawm tias lub Hoobkas- rov kho lub koob yees duab. Tsis muaj leej twg xav txheeb xyuas qhov uplink. Peb nug ib lo lus nug: "Dab tsi yog txuas koj qhov kev nkag mus rau lub hauv paus?" Teb: ib qho gigabit tooj liab.
Qhov ntawd yog qhov ua tsis taus pa. Plaub caug- yim lub koob yees duab thawb ib txhij HD video los ntawm ib lub yeeb nkab 1Gbps. Peb xa plaubSFP-10G-SRmodules thiab OM3 patchcords los ntawm SF Express. Lawv cov engineers swapped uplinks hnub Friday yav tav su. Hnub Monday sawv ntxov, 46 lub koob yees duab online, pob zeb.
Lwm ob? Tseem poob qis. Tig tawm ob qhov kev khiav haujlwm no yog Cat5e tshuav los ntawm 2016 lub xov tooj nruab. Txhua yam yog Cat6. Tus neeg siv khoom cov lus tseeb thaum peb hais rau nws: "Kuv paub tias kev yuav khoom yuav rov qab los tom kuv ntawm cov kab uas pheej yig." Hloov ob txoj kev khiav, ua tiav.
Tag nrho cov nqi ntawm peb kho: ¥ 1,180 hauv optics thiab fiber ntau. Tus neeg koom ua ke tau hais txog ¥ 126,000 los hloov tag nrho pawg hloov pauv. Tus nqi sib txawv ntawd yog vim li cas peb thiaj li tau xaj rov qab.
Xaiv tus qauv PoE yam tsis xav txog nws
802.3af muab rau koj 12.95W ntawm lub cuab yeej. Txaus rau lub rooj xov tooj thiab lub qhov rooj sensors, tsis muaj dab tsi ntxiv . 802.3 txog 25.5W, npog feem ntau lub koob yees duab IP thiab WiFi 6 APs. 802.3bt Hom 3 thiab Hom 4 kov 51W thiab 71.3W raws li, uas yog qhov twg WiFi 6E, PTZ koob yees duab nrog cov cua sov, thiab LED vaj huam sib luag nyob.
Nov yog peb cov lus pom zoo, thiab qhov laj thawj yog kev lag luam, tsis yog kev: yuav 802.3bt injectors txawm tias niaj hnub no cov khoom siv tsuas yog xav tau 802.3at.
Vim li cas? Vim tias peb saib ib tus neeg siv khoom hauv Nyab Laj yuav 200 units ntawm 802.3at injectors hauv Q3 2024. Yim lub hlis tom qab, lawv tus neeg muag khoom WiFi tau thawb lawv hloov mus rau WiFi 6E cov ntsiab lus nkag tau kos 38W txhua. Txhua tus injector ua tsis muaj txiaj ntsig. Lawv reordered 200 units ntawm 802.3bt. Tus thawj coj nyiaj txiag hu rau peb tus neeg muag khoom nug seb peb puas yuav rov qab cov qub. (Peb ua tsis tau. Tsis muaj leej twg ua tau.)
Tus bt injector raug nqi kwv yees li ntawm $ 12 ntau dua ib chav dua li ntawm. Ntawm 200 units uas yog $2,400 ntxiv. Tus nqi ntawm Nyab Laj tus neeg siv khoom yuam kev: $ 4,400 hauv khib nyiab ntawm cov tshuaj txhaj tshuaj ntxiv rau $ 2,400 hauv kev xa khoom sai rau kev hloov pauv, ntxiv rau peb lub lis piam ntawm kev ua haujlwm tsis zoo ntawm WiFi thoob plaws hauv lawv lub tsev hauv tsev. Cisco tus kheej daim ntawv qhia kev xa tawm sau tseg tias tsis muaj zog WiFi 7 APs ntsiag to poob los ntawm 4 × 4 MIMO rau 2 × 2 hom (ciscopress.com). Koj cov neeg siv yuav tsis pom cov lus yuam kev. Lawv tsuas pom kev sib txuas qeeb thiab liam rau pab pawg IT.
Qhov Tsis Muaj PoE Phau Ntawv Qhia Hais Txog: Koj qhov Uplink yog qhov tiag tiag lub raj mis
Feem ntau cov ntawv PoE nres ntawm qhov txhaj tshuaj. Injector xaiv, ua haujlwm tiav. Tab sis lub injector tsuas yog daws lub zog xa mus rau qhov kawg. Cov ntaub ntawv los ntawm cov ntsiab lus kawg no tseem yuav tsum ncav cuag koj lub network tseem ceeb los ntawm qhov hloov pauv qhov chaw nres nkoj uplink. Thiab qhov no yog qhov project ntsiag to poob.
Rov qab- ntawm- kev suav cov ntaub so ntswg: 48 lub koob yees duab ntawm 4Mbps txhua=192Mbps txhawb nqa. Ntxiv nyiaj siv ua haujlwm, spikes thaum lub sijhawm ua haujlwm, thiab koj tau thawb 300-400Mbps los ntawm qhov txuas tau yooj yim. Ntawm daim ntawv, gigabit tooj liab tuav nws. Hauv kev xyaum, ib zaug koj ua rau lwm yam VLAN tsheb khiav ntawm tib qhov kev hloov, koj tab tom khiav ntawm 70-80% kev siv ntawm uplink thaum lub sij hawm ncov. Uas tawm tsis muaj headroom. Ib qho cua daj cua dub tshaj tawm, ib lub firmware thawb, thiab lub koob yees duab pib buffering.
10G fiber uplink tshem tawm qhov kev txwv no rau tsib mus rau xya xyoo tom ntej ntawm kev loj hlob ntawm cov cuab yeej. Tus nqi?
