Kuti tizive hurefu hwekutapurirana chinhambwe chePoE, tinofanira kutanga tafunga kuti ndezvipi zvinhu zvakakosha zvinotaridza kureba kureba.Muchokwadi, kushandisa yakajairwa Ethernet tambo (yakamonyoroka peya) kuendesa DC simba rinogona kutakurwa pamusoro pechinhambwe chakareba, icho chakakura kwazvo kupfuura chinhambwe chekufambisa kwezviratidzo zve data.Naizvozvo, kureba kureba kwekufambisa data ndiyo kiyi.

1. Iyo yakanyanya kureba ye network cable data transmission

Isu tinoziva zvakawanda nezve network tinoziva kuti akamonyoroka maviri ane "isingakundike" yekufambisa kureba ye "100 metres".Ingave iri Chikamu 3 chakamonyoroka pair ine 10M transmission rate, Chikamu 5 chakamonyoroka pair ine 100M transmission rate, kana kunyange Chikamu 6 chakamonyoroka peya ine 1000M yekutapurirana mwero, iyo yakareba inoshanda yekufambisa chinhambwe i100 metres.

Muchigadziro chekubatanidza wiring, inotarisirwawo zvakajeka kuti wiring yakatwasuka haifaniri kudarika mamita makumi mapfumbamwe, uye urefu hwese hwekubatanidza haufaniri kudarika 100 mamita.Izvo zvakati, 100 metres muganho wewaya Ethernet, inova kureba kwekubatanidza kubva kunetiweki kadhi kuenda kune hub mudziyo.

2. Wakawana sei kureba kwemamita zana?

Chii chakakonzera muganhu wepamusoro we100-mita yekufambisa kureba kwepeya yakamonyoroka?Izvi zvinoda kunyura kwakadzika mukati memisimboti yemuviri yakadzika yevaviri vakamonyoroka.Iko kutapurirana kwetiweki ndiko chaizvo kutapurirana kwechiratidzo chetiweki pamutsara wakamonyoroka.Sechiratidzo chemagetsi, kana ichiparidzirwa mumutsara wakamonyoroka, inofanira kukanganiswa nekupikisa uye capacitance, iyo inotungamirira pakuderedza uye kukanganisa kwechiratidzo chetiweki.Kana iyo attenuation kana kukanganisa kwechiratidzo kunosvika kune imwe nhanho, iyo inoshanda uye yakagadzikana kutumira kwechiratidzo kuchakanganiswa.Naizvozvo, maviri akamonyoroka ane danho rekutapurirana.

3. Maximum cable kureba panguva yekuvaka chaiyo

Zvinogona kuonekwa kubva pamusoro kuti nei kureba kwetambo yetiweki isingapfuuri mamita zana kana uchishandisa PoE magetsi.Nekudaro, mukuvaka chaiko, kuitira kuve nechokwadi chemhando yeprojekiti, kazhinji kutora 80-90 metres.

Ndokumbira utarise kuti chinhambwe chekufambisa pano chinoreva chiyero chepamusoro, senge 100M.Kana iyo chiyero ichideredzwa kusvika ku10M, kureba kwekufambisa kunogona kuwedzerwa kusvika ku150-200 mamita (zvichienderana nehutano hwetambo yetiweki).Naizvozvo, kureba kwekufambisa kwePoE magetsi haagadzirwe nePoE tekinoroji, asi nemhando uye mhando yetambo network.
