PoE canzana’ura ce da ake amfani da ita sosai a masana’antar tsaro a yau, domin ita ce mai sauya wuta da ke ba da wutar lantarki da watsa bayanai don musaya daga nesa (kamar wayar IP ko kyamara), kuma tana taka muhimmiyar rawa.Lokacin amfani da maɓallan PoE, wasu maɓallan PoE ana yiwa alamar PoE, wasu kuma ana yiwa alamar PoE+.Don haka, menene bambanci tsakanin canjin PoE da PoE +?

1. Menene canjin PoE

An ayyana maɓallan PoE ta ma'auni na IEEE 802.3af kuma suna iya samar da har zuwa 15.4W na ƙarfin DC kowace tashar jiragen ruwa.

2. Me yasa amfani da maɓalli na PoE

A cikin 'yan shekarun da suka gabata, ya zama ruwan dare ga 'yan kasuwa su shimfiɗa hanyoyin sadarwa daban-daban guda biyu, ɗaya don wutar lantarki ɗayan kuma don bayanai.Koyaya, wannan ya ƙara rikitarwa ga kulawa.Don magance wannan, gabatarwar PoE switch.Koyaya, kamar yadda buƙatun wutar lantarki na tsarin hadaddun da ci-gaba kamar cibiyoyin sadarwar IP, VoIP, da canjin sa ido, Maɓallin PoE ya zama muhimmin ɓangare na kamfanoni da cibiyoyin bayanai.

3. Menene canza POE +

Tare da haɓaka fasahar PoE, sabon IEEE 802.3at misali ya bayyana, wanda ake kira PoE +, kuma masu sauyawa dangane da wannan ma'auni kuma ana kiran su PoE+ switches.Babban bambanci tsakanin 802.3af (PoE) da 802.3at (PoE +) shi ne cewa na'urorin samar da wutar lantarki na PoE + suna samar da wutar lantarki kusan sau biyu fiye da na'urorin PoE, wanda ke nufin cewa yawancin wayoyin VoIP, WAPs da kyamarori IP za su yi aiki akan tashoshin PoE +.

4. Me yasa kuke buƙatar POE+ masu sauyawa?

Tare da karuwar buƙatun haɓakar wutar lantarki mai girma PoE a cikin kamfanoni, na'urori irin su wayoyin VoIP, wuraren samun damar WLAN, kyamarori na cibiyar sadarwa da sauran na'urori suna buƙatar sabbin maɓalli tare da babban iko don tallafawa, don haka wannan buƙatar kai tsaye ta haifar da haihuwar PoE + switches.

5. Amfanin PoE+ switches

a.Babban iko: Maɓallin PoE + na iya samar da har zuwa 30W na wutar lantarki a kowane tashar jiragen ruwa, yayin da maɓallan PoE na iya samar da har zuwa 15.4W na wutar lantarki ta tashar jiragen ruwa.Matsakaicin ƙarfin da ake samu akan na'urar da aka kunna don sauyawar PoE shine 12.95W kowace tashar jiragen ruwa, yayin da mafi ƙarancin ƙarfin da ake samu don sauya PoE+ shine 25.5W kowace tashar jiragen ruwa.

b.Ƙarfi mai ƙarfi: PoE da PoE + masu sauyawa suna rarraba matakan daga 0-4 bisa ga yawan wutar lantarki da ake bukata, kuma lokacin da aka haɗa na'urar samar da wutar lantarki zuwa na'urar samar da wutar lantarki, yana ba da ajinsa ga na'urar samar da wutar lantarki don na'urar samar da wutar lantarki. zai iya samar masa da daidai adadin iko .Layer 1, Layer 2, da Layer 3 na'urorin suna buƙatar ƙarancin ƙarfi, ƙananan, da matsakaicin amfani da wutar lantarki, bi da bi, yayin da Layer 4 (PoE +) masu sauyawa suna buƙatar iko mai yawa kuma suna dacewa da kayan wuta na PoE + kawai.

c.Ƙarin rage farashin: Wannan PoE + mafi sauƙi yana amfani da ma'auni na cabling (Cat 5) don aiki tare da mu'amalar Ethernet na yau da kullun, don haka ba a buƙatar "sabon waya" da ake buƙata.Wannan yana nufin cewa ana iya amfani da kayan aikin kebul na cibiyar sadarwa da ake da su ba tare da buƙatar gudanar da wutar lantarki mai ƙarfi ta AC ba ko keɓancewar haɗin wutar lantarki don kowane maɓalli da aka saka.

d.Ƙarfin ƙarfi: PoE + yana amfani da kebul na cibiyar sadarwa na CAT5 kawai (wanda ke da wayoyi na ciki 8, idan aka kwatanta da wayoyi 4 na CAT3), wanda ke rage yiwuwar rashin ƙarfi kuma yana rage amfani da wutar lantarki.Bugu da ƙari, PoE + yana ba da damar masu gudanar da cibiyar sadarwa don samar da ayyuka mafi girma, kamar samar da sababbin bincike na wutar lantarki mai nisa, rahoton matsayi, da sarrafa wutar lantarki (ciki har da hawan keke mai nisa na masu sauyawa).

A ƙarshe, Maɓallin PoE da PoE+ na iya kunna wutar lantarki ta hanyar sadarwa kamar kyamarori na cibiyar sadarwa, APs, da wayoyi na IP, kuma suna da babban sassauci, babban kwanciyar hankali, da babban kariya ga tsangwama na lantarki.
