[AipuWaton] Kumvetsetsa Kutalikira Kwambiri Kutumiza kwa PoE Technology

Ukadaulo wa Power over Ethernet (PoE) wasintha momwe timatumizira zida zama netiweki polola kuti mphamvu ndi data zitumizidwe pa ma cabling wamba a Efaneti. Komabe, ogwiritsa ntchito ambiri amadabwa kuti mtunda wautali wotumizira wa PoE ndi wotani. Kumvetsetsa zinthu zomwe zimakhudza mtunda uwu ndikofunikira pakukonzekera bwino kwa maukonde ndikuchita.

Kodi N'chiyani Chimatsimikizira Kutali Kwambiri kwa PoE?

Chofunikira pakuzindikira mtunda wautali wa PoE ndi mtundu ndi mtundu wa chingwe chopotoka chomwe chimagwiritsidwa ntchito. Miyezo yodziwika bwino ya ma cabling ndi:

Shanghai-Aipu-Waton-Electronic-Industries-Co-Ltd-

Gulu 5 (mphaka 5)

Imathandizira kuthamanga mpaka 100 Mbps

Gulu 5e (Mphaka 5e)

Mtundu wowongoleredwa ndi magwiridwe antchito abwino, komanso umathandizira 100 Mbps.

Gulu 6 (mphaka 6)

Imatha kunyamula liwiro mpaka 1 Gbps.

Mosasamala kanthu za mtundu wa chingwe, miyezo yamakampani imakhazikitsa mtunda wothamanga kwambiri wamamita 100 (mamita 328) pakulumikizana kwa data pazingwe za Efaneti. Malire awa ndi ofunikira pakusunga kukhulupirika kwa data ndikuwonetsetsa kulumikizana kodalirika.

Sayansi Pambuyo pa Malire a 100-Meter

Potumiza ma sign, zingwe zopotoka zimakumana ndi kukana komanso mphamvu, zomwe zingayambitse kuwonongeka kwa ma sign. Pamene chizindikiro chikudutsa chingwe, chikhoza kubweretsa:

Kuchepetsa:

Kutayika kwa mphamvu ya chizindikiro pa mtunda.

Lakwitsidwa:

Kusintha kwa mawonekedwe a ma waveform, zomwe zimakhudza kukhulupirika kwa data.

Khalidwe lazizindikiro likachepa kupitilira malire ovomerezeka, zimakhudza mitengo yotumizira bwino ndipo zingayambitse kutayika kwa data kapena zolakwika za paketi.

Kuwerengera Distance Yotumiza

Kwa 100Base-TX, yomwe imagwira ntchito pa 100 Mbps, nthawi yotumizira pang'ono data, yotchedwa "bit time," imawerengedwa motere:

[ \text{Bit Time} = \frac{1}{100 , \text{Mbps}} = 10 , \text{ns} ]

Njira yotumizirayi imagwiritsa ntchito CSMA/CD (Carrier Sense Multiple Access with Collision Detection), kulola kuzindikira kugundana koyenera pamanetiweki omwe amagawana nawo. Komabe, ngati chingwe chitalikirapo kuposa mamita 100, mwayi wozindikira kugunda kumachepa, zomwe zingawononge kutayika kwa data.

Ndikofunikira kudziwa kuti ngakhale kutalika kwake kumayikidwa pa 100 metres, zinthu zina zitha kuloleza kusinthasintha kwina. Kuthamanga kocheperako, mwachitsanzo, kumatha kukulitsa mtunda wogwiritsiridwa ntchito mpaka 150-200 metres, kutengera mtundu wa chingwe ndi ma network.

Malangizo Othandiza Pautali Wachingwe

Pokhazikitsa zenizeni padziko lapansi, kutsatira mosamalitsa malire a mita 100 ndikofunikira. Komabe, akatswiri ambiri amtaneti amalimbikitsa kukhalabe mtunda wa 80 mpaka 90 metres kuti muwonetsetse kudalirika ndikuchepetsa zovuta zilizonse zomwe zingachitike. Mphepete mwachitetezo ichi imathandizira kusiyanasiyana kwamtundu wa chingwe komanso kuyika.

Ngakhale zingwe zapamwamba nthawi zina zimatha kupitilira malire a mita 100 popanda zovuta zaposachedwa, njira iyi siyovomerezeka. Mavuto omwe angakhalepo amatha kuwonekera pakapita nthawi, zomwe zimabweretsa kusokonezeka kwakukulu kwa maukonde kapena kusagwira ntchito mokwanira pambuyo pa kukonzanso.

Mapeto

Mwachidule, mtunda wautali wotumizira ukadaulo wa PoE umakhudzidwa makamaka ndi gulu la zingwe zopotoka komanso zofooka zapanthawi yotumizira ma siginecha. Malire a 100-mita amakhazikitsidwa kuti athandize kusunga deta ndi kudalirika. Potsatira njira zolimbikitsira ndikumvetsetsa mfundo zazikuluzikulu zotumizira ma Ethernet, akatswiri pamaneti amatha kuonetsetsa kuti maukonde akugwira ntchito mwamphamvu komanso moyenera.
