I tēnei rā, me whakamārama e au te hanganga taipitopito o ngā taura Ethernet moana. He māmā noa iho, ko ngā taura Ethernet paerewa he ara iahiko, he paparanga whakamarumaru, he paparanga ārai, me te paparanga o waho, ko ngā taura ārai he paparanga o roto me te paparanga ārai i waenganui i te ārai me te paparanga o waho. Mārama noa, ehara i te mea he tiaki ā-ringa tāpiri anake ngā taura ārai engari he paparanga o roto anō hoki hei tiaki. Nā, me tirotiro tātou i ia wāhanga kia mārama.
1. Kaiārahi: Te Matua o te Tuku Tohu
He maha ngā rauemi o ngā taura Ethernet, tae atu ki te parahi tine, te parahi tahanga, te waea konumohe, te konumohe whakakikoruatia ki te parahi, me te maitai whakakikoruatia ki te parahi. E ai ki te IEC 61156-5:2020, me whakamahi ngā taura Ethernet moana i ngā taura parahi totoka kua whakamahanahia, he whānui kei waenganui i te 0.4mm me te 0.65mm. I te pikinga ake o ngā tono mō ngā tere tuku me te pumau teitei ake, kei te whakakorea haeretia ngā taura iti iho i te kounga pērā i te konumohe me te konumohe whakakikoruatia ki te parahi, ā, ko te parahi tine me te parahi tahanga kei te kaha ake i te mākete.
Ki te whakatauritea ki te parahi tahanga, he pai ake te pumau matū o te parahi tine, te ātete ki te waikura, te waikura matū, me te makuku hei pupuri i te pono o te ara iahiko.
E rua ngā hanganga o ngā kaiārahi: he totoka, he taura hoki. Kotahi te waea parahi e whakamahia ana e ngā kaiārahi totoka, ā, he maha ngā waea parahi angiangi e whiria ana. Ko te rerekētanga matua kei roto i te mahi tuku – nā te mea ka whakaitihia te ngaronga whakaurunga e ngā horahanga whakawhiti nui ake, ka whakaatuhia e ngā kaiārahi taura he 20%-50% teitei ake te whakaiti i te kaha o te hiko i ngā mea totoka. Ka whakanuia hoki e ngā āputa i waenga i ngā aho te ātete DC.
Ko te nuinga o ngā taura Ethernet e whakamahi ana i ngā ara iahiko 23AWG (0.57mm) 24AWG rānei (0.51mm). Ahakoa e whakamahi ana te CAT5E i te 24AWG, ko ngā kāwai teitei ake pērā i te CAT6/6A/7/7A e hiahia ana ki te 23AWG mō te mahi pai ake. Heoi, kāore ngā paerewa IEC e whakahau ana i ngā ine waea motuhake – ka taea tonu e ngā taura 24AWG kua hangaia pai te whakatutuki i ngā whakaritenga CAT6+.
2. Papa Ārai: Te Tiaki i te Pono o te Tohu
Ka ārai te paparanga ārai i te turuturu o te tohu i te wā e tukuna ana. E ai ki ngā paerewa IEC 60092-360 me GB/T 50311-2016, ka whakamahia e ngā taura moana tepolyethylene matotoru (HDPE)pahuka rāneipolyethylene (Huka PE). He tino pai te ātete o te HDPE ki te pāmahana, ki te kaha miihini, me te ātete pakaru i te ahotea taiao, ā, he mea whānui te whakamahinga. He pai ake ngā āhuatanga dielectric o te pahuka PE, ā, he mea tino pai mō ngā taura CAT6A+ tere-teitei.
3. Wehewehe Whakawhiti: Te Whakaiti i te Whakawhitiwhiti Tohu
Ko te wehewehe whakawhiti (e mōhiotia ana ko te whakakī whakawhiti) he mea hanga hei wehewehe ā-tinana i ngā takirua miro e whā kia motuhake, kia whakaitihia ai te whakawhitiwhiti kōrero i waenga i ngā takirua. He mea hanga mai i te rauemi HDPE me te diameter paerewa o te 0.5mm, he mea nui tēnei wāhanga mō ngā taura Kāwai 6 me ngā taura teitei ake e tuku raraunga ana i te 1Gbps, tere ake rānei, nā te mea he nui ake te aro o ēnei taura ki te haruru tohu, ā, me kaha ake te ātete ki te pokanoa. Nō reira, ko ngā taura Kāwai 6 me runga ake kāore he parenga takirua takitahi ka whakauruhia he whakakī whakawhiti hei wehe i ngā takirua miro e whā.
He rerekē, ko ngā taura Kāwai 5e me ērā e whakamahi ana i ngā hoahoa pepa whakakikorua-parepare kāore e whakamahi i te whakakī whakawhiti. Ko te whirihoranga takirua-whiri o ngā taura Cat5e e whakarato ana i te tiakitanga pokanoa e ranea ana mō ā rātou whakaritenga whānui iti ake, e kore ai e hiahiatia he wehenga atu. Waihoki, ko ngā taura me ngā takirua kua āraia-pepa whakakikorua e whakamahi ana i te kaha o te pepa whakakikorua konumohe ki te aukati i te pokanoa hiko auau teitei, e kore ai e hiahiatia te whakakī whakawhiti.
He mea nui te kaha o te taura ki te ārai i te roa o te taura, ka pā kino pea ki te mahi. Ko te nuinga o ngā kaihanga taura matua o te ahumahi e whakamahi ana i te taura muka karāhe, i te taura nairona rānei hei wāhanga whakakaha i roto i ā rātou hanganga taura. Ka whakaratohia e ēnei rauemi he tiaki miihini tino pai, me te pupuri tonu i ngā āhuatanga tuku o te taura.
4. Paparanga Parepare: Parenga Hikohiko
Ko ngā paparanga ārai he mea hanga ki te pepa konumohe me/ranei te mata whiri hei ārai i te EMI. Ko ngā taura ārai-kotahi e whakamahi ana i te paparanga pepa konumohe kotahi (≥0.012mm te matotoru me te ≥20% te taupatupatu) me te paparanga PET mylar hei ārai i te turuturu o te iahiko. E rua ngā momo o ngā putanga ārai-rua: SF/UTP (pepa whānui + whiri) me te S/FTP (pepa takirua takitahi + whiri whānui). Ko te whiri parahi tine (≥0.5mm te whānui o te waea) ka taea te whakarite i te kapinga (ko te tikanga he 45%, 65%, 80% rānei). E ai ki te IEC 60092-350, ko ngā taura moana ārai-kotahi e hiahia ana ki te waea whakaheke mō te whenua, ko ngā putanga ārai-rua e whakamahi ana i te whiri mō te tukunga hiko.
5. Paparanga Pūkahu: Parenga Ā-ringa
Ka whakarei ake te paparanga pukupuku i te ātete ki te kuru/te pakaru, ā, ka whakapai ake hoki i te parenga EMI. Ko ngā taura moana e whakamahi ana i te pukupuku whiri i runga i te ISO 7959-2, me te waea maitai piauau (GSWB) e whakarato ana i te kaha teitei me te ātete wera mō ngā tono uaua, ko te waea parahi tine (TCWB) e whakarato ana i te ngāwari ake mō ngā wāhi kuiti.
6. Uhi o Waho: Parepare Taiao
Me maeneene te anga o waho, me porowhita, ā, me tango atu, me te kore e kino ngā paparanga o raro. Ko ngā paerewa DNV e hiahia ana kia 0.04×Df (diameter o roto) +0.5mm te matotoru (Dt), me te iti rawa 0.7mm. Ko ngā taura moana te nuinga o te whakamahiLSZH (auahi iti, kore-halogen)ngā rauemi (ngā māka SHF1/SHF2/SHF2 MUD e ai ki te IEC 60092-360) e whakaiti ana i ngā kohu paitini i te wā o te ahi.
Whakamutunga
Kei roto i ia paparanga o ngā taura Ethernet moana he mahi hangarau ātaahua. I OW CABLE, e whakapau kaha ana mātou ki te whakatairanga i te hangarau taura – tēnā koa kōrero mai ki a mātou mō ō hiahia!
