Kunze kwetambo yetiweki, chii chimwe chinokanganisa PoE simba rekufambisa chinhambwe?
PoE inogona kufambisa data kuburikidza netambo yetiweki ichipa simba kuPoE terminal zvishandiso senge waya AP, network kamera, IP foni, PAD, nezvimwewo, ine chinhambwe chekufambisa chinosvika zana metres. Sezvo iyo PoE yemagetsi system iri nyore kuisa uye plug-uye-kutamba, yakanyatsokodzera kushandiswa mumaindasitiri akadai seakangwara maguta uye kuchengetedzwa kwekutarisa.
- Zvinhu zvikuru zvinokanganisa PoE kutapurirana kureba
1-1. Network cable quality
Iyo data chiratidzo chekufambisa chinhambwe cheakajairwa Chikamu 5 tambo dzinenge 100 metres. Tichifunga nezvezvinhu zvakaita senge chiteshi attenuation muinjiniya, 80-90 metres inowanzotorwa kuti ive nechokwadi chekuvaka. Nzvimbo yekufambisa pano inoreva huwandu hwepamusoro, hwakadai se100M. Nekudaro, kana chiyero chakadzikiswa kusvika ku10M, kureba kwekufambisa kunogona kukwidziridzwa kusvika ku150-250 metres, zvichienderana nemhando yetambo network.
Iyo PoE simba rekupa chinhambwe chakabatana zvakanyanya nezvinhu zvetiweki tambo. Iyo yakaderera iyo impedance yetambo yetiweki, iyo yakareba kureba kwekufambisa.
1-2. Cable kuisa uye kupisa kupisa
Kuwedzera kwekushisa kwetambo kunozotungamira mukudzikira kwechaneli attenuation uye kuisa kurasikirwa kuita. Pakuisa tambo dzePoE, kukanganisa kwetambo yekuisa pakupisa kupisa kunofanirwa kutariswa.
Nokudaro, paunenge uchiisa tambo, teerera kutora nzira inobatsira pakupisa kupisa.
1-3. PoE chinja kuita
Iyo network yakasimba haingoenderana chete neiyo PoE magetsi ekupa chinhambwe, asi zvakare netiweki yekufambisa mhando inofanirwa kuvimbiswa. Zvinoenderana nemirairo yeIEEE, kana network tambo yekufambisa ichipfuura 100 metres, mhando yekufambisa inogona kunge isina kuvimbiswa.
Nekudaro, mune zvimwe zviitiko (pasi pekumanikidzwa kwemutengo), senge pakuisa kamera, kureba kunogona kudarika 100 metres. Kana chinhambwe chisiri kure zvakanyanya, kuseta chiyero chekubatanidza kamera kusvika ku10M kunogona kuwedzera nzvimbo yekufambisa yePoE kusvika ku150-250 metres.
Kuti uwane kureba kwekufambisa chinhambwe, iyo PoE switch ine zvakaomesesa zvinodikanwa patambo yetiweki uye kuita kwayo kwayo kwakakosha. Kana iyo yemukati switching chip yePoE switch ine hurombo hwekuzvigadzirisa kugona uye iyo simba chip manejimendi kugona haina kusimba, kunyangwe chiyero chekufambisa chikamanikidzwa kuve 10M, haigone kuvimbisa kugadzikana kwekutapurirana kwemamita mazana maviri nemakumi mashanu, uye kunyange 150 metres haigone. zviwanikwe.
Kuti isangane nemusika kudiwa, JHA Tech yatanga nhevedzano yekureba-kure kufambisa PoE Switch.
- 2. Pfungwa huru
PoE magetsi emagetsi ane zvinodiwa zvakanyanya kune waya. Hunhu hwetambo dzenetiweki hune hukama nehurefu hwekufambisa uye kugadzikana kwekutapurirana kwePoE. Hupenzi kutaura nezve transmission distance pasina kufunga nezve network cables. Mumapurojekiti ekuongorora, usachengetedza mari pawaya, kuitira kuti usarasikirwe kupfuura iwe.
