Pehea e hoʻoholo ai i ke kaula coaxial no ka Pūnaewele
Nā mea
Ma hope o ka heluhelu ʻana i kēia ʻatikala, hiki iā ʻoe ke haʻi i ka ʻokoʻa ma waena o ke kelepona pūnaewele coaxial a me nā kaula coaxial āpau i kou home.
Hoʻohana ʻia nā kaula coaxial ma nā wahi like ʻole e like me ka leo, wikiō a me ka ʻikepili pūnaewele. No laila, paʻakikī ka ʻike ʻana i ke kaula coaxial i hoʻohana ʻia no ka Pūnaewele. No laila, ʻo wai ke kelepona coaxial e hoʻopili ai au i kaʻu mea hoʻokele? Eia pehea e hoʻoholo ai i ke kaula coaxial no ka pūnaewele.
ʻO ka maʻamau, hiki iā ʻoe ke hoʻohana i ka helu RG ma nā uea e ʻike ai i ke kelepona pūnaewele coax. Hoʻohana mau ʻia nā kaula RG-8, RG-6 a me RG-58 no ka lawe ʻana i ka ʻikepili ma ka Pūnaewele. Hiki iā ʻoe ke ʻike i kēia mau hōʻailona ma ka hopena o ke kaula coaxial a i ʻole ma waena.
E heluhelu i ka ʻatikala ma lalo no ka wehewehe kikoʻī.
ʻO ke ala maikaʻi loa e ʻike ai i nā kaula coaxial no ka Pūnaewele
I kēia manawa, hoʻohana ʻia nā kaula coaxial no ka lekiō, televise a me nā pili pūnaewele.
I kēia manawa, ke ʻimi nei paha ʻoe i kahi hui o nā kaula coax a ʻaʻole ʻoe i ʻike ʻo wai ia. I ka pilikia, ʻaʻole ʻoe e ʻike i ke kelepona e hoʻopili ai i kāu router. ʻO ia ke kumu he mea nui ka ʻike ʻana i ke kelepona pūnaewele coaxial.
Me ka noʻonoʻo, eia kahi ala maʻalahi a wikiwiki e ʻimi ai i nā kaula coaxial no ka pūnaewele ma waena o nā mea ʻē aʻe.
Ka ʻike ʻana i kahi kaula coaxial e ka helu RG
ʻO nā helu RG ke ala maikaʻi loa e ʻike ai i nā kelepona pūnaewele coaxial. Akā he aha nā helu RG?
Kū ʻo RG no ka Radio Guide. I ka hoʻokaʻawale ʻana i nā kaula coaxial, hoʻohana nā mea hana i kēia inoa RG me nā helu e like me RG-6, RG-59, RG-11, a me nā mea ʻē aʻe.
ʻO nā kaula coaxial i hoʻohana ʻia e hoʻopili i ka Pūnaewele ua kapa ʻia ʻo RG-6, RG-8, a me RG-58. ʻO kēia mauʻanoʻekolu ka mea maʻamau.
No laila, ʻo nā mea a pau āu e hana ai, ʻo ka ʻimi ʻana i ka hōʻailona RG ma ke kaula, a aia ka māka ma ka hope o ka mea hoʻohui o ke kaula, a i ʻole ma waena.
Eia naʻe, inā ʻoe e hoʻohana nei i nā kaula kahiko, ʻaʻole hiki iā ʻoe ke ʻike pololei i nā kaha. I kekahi manawa ua uhi ʻia nā kaha me ka lepo. Inā pēlā, hoʻomaʻemaʻe i ka uwea a nānā i ka helu RG.
Eia kekahi mau mea e ʻike ai e pili ana i nā kaula coaxial RG i ʻōlelo ʻia ma luna.
E nānā i ke kiʻi ma luna. He hoʻohālikelike kēia ma waena o nā kaula RG-58 a me RG-6. ʻO ke kaula ma ka hema ʻo RG-58 a ma ka ʻākau ʻo RG-6. E like me kāu e ʻike ai, ʻoi aku ka mānoanoa o ke kaula RG-6 ma mua o ke kaula RG-58. Me kēia hoʻohālikelike, hiki iā ʻoe ke hoʻomaopopo maʻalahi i ka nui o ke kaula RG-8.
RG-58
Hoʻohana nui ʻia ke kaula RG-58 no nā noi 50 ohm. ʻO 20 AWG ke ana.
RG-8
ʻO RG-8 kahi kaula mānoanoa 50 ohm. ʻO 12 AWG ke ana.
RG-6
Hiki i ke kaula RG-6 ke lawelawe i nā noi 75 ohm. ʻO 18 AWG ke ana.
He aha ke kelepona maikaʻi loa no ka pūnaewele?
Manaʻo wau he mau koho maikaʻi kēia o nā kelepona ʻekolu i luna no ka pūnaewele. Akā inā pono wau e koho, e koho wau i ka RG-6.
He ʻāpana ʻoi aku ka mānoanoa o ke kaula RG-6 a ʻoi aku ka mānoanoa. Pēlā nō, maikaʻi kona bandwidth kiʻekiʻe no nā noi e like me ka Internet, satellite TV, a me ka TV cable.
I kēia manawa ua ʻike ʻoe pehea e koho ai i kahi kaula coaxial no ka Pūnaewele. Akā ʻike anei ʻoe pehea e hoʻoholo ai i ka hopena coaxial i loaʻa ka hōʻailona maikaʻi loa?
No ka hana ʻana i kēia, pono ʻoe i kahi hōʻike uea coaxial. A eia pehea e hiki ai iā ʻoe ke hoʻohana iā ia e ʻike i ka hopena coax maikaʻi loa.
- E hoʻā i ka mea hōʻike uwea coaxial.
- E lawe mai i ka mea hōʻike i kahi puka kikoʻī.
- Inā ʻulaʻula ka hōʻailona LED, nāwaliwali ka hōʻailona.
- Inā ʻōmaʻomaʻo ka hōʻailona LED, ikaika ka hōʻailona.
ʻ Tiplelo Aʻoaʻo wikiwiki: Ma mua o ka hoʻopili ʻana i ke kākoʻo i kēlā me kēia manawa e nalowale ana ʻoe i ka hōʻailona, ʻoi aku ka maikaʻi o ka loaʻa ʻana o kahi hōʻike kelepona coax.
He aha kāu e ʻike ai e pili ana i nā kaula coaxial no ka Pūnaewele
mea i manao ai
ʻO kēia mau uwea pūnaewele coaxial he hoʻolālā mānoanoa poepoe a me kahi alakaʻi kikowaena keleawe. Eia naʻe, ʻoi aku ka nui o ka mānoanoa o ke kaula i ka insulation (ma mua o ka conductor keleawe). Ma muli o ka insulation nui, hiki i ka conductor keleawe ke hoʻouna i ka ʻikepili me ka ʻole o ka pōʻino o waho a i ʻole ke keakea ʻana.
ʻO kahi insulator dielectric plastic e pale i ka conductor keleawe. Aia ma luna o ka plastic dielectric insulator he pale metala. ʻO ka mea hope loa, ʻo ka puʻu plastik waho e pale ai i ka insulation o loko a me ka conductor.
Hana ʻōnaehana
ʻO ka lawe ʻana i ka ʻikepili ma luna o kahi conductor keleawe ka hana o nā kaula coaxial no ka Pūnaewele. Mahalo i nā papa ʻokoʻa, ʻaʻole ʻoe e ʻike i ka nalowale o ka hōʻailona. I nā huaʻōlelo ʻē aʻe, hoʻemi ia i ka interference electromagnetic.
ʻO ka wikiwiki
Hiki i kēia mau uwea pūnaewele ke hoʻoili i ka ʻikepili ma ka wikiwiki mai ka 10 Mbps a i ka 100 Mbps (megabits per second).
Nīnau pinepineʻia
Pehea ka lōʻihi e hele ai ke kelepona pūnaewele coaxial?
Ua ʻike ʻia nā kaula coaxial no ka lōʻihi o ka lōʻihi ma mua o ka nui o nā kaula ʻē aʻe. Hiki iā lākou ke holo a hiki i 500 m. He 1640.4 kapuaʻi kēia waiwai. Eia nō naʻe, ʻokoʻa paha kēia waiwai ma muli o ke ʻano kelepona a me ka ikaika hōʻailona.
E pili ana ka lōʻihi o ke kaula coaxial i ka hōʻailona pūnaewele?
ʻAe, pili ka lōʻihi o ke kaula i ka hōʻailona pūnaewele. No ka laʻana, e ʻike ʻoe i ka nalowale o ka hōʻailona me ka lōʻihi o ke kaula. ʻO kēia poho hōʻailona ma muli o ke kū'ē.
Ke piʻi aʻe ka lōʻihi o ka conductor, piʻi koke ke kū'ē o ka conductor. No laila, ʻo ka mamao lōʻihi ke ʻano o ke kūpaʻa kiʻekiʻe, ʻo ia ka nalowale o ka hōʻailona pūnaewele.
E like me ke kānāwai, e like me ka piʻi ʻana o ka mamao mai ka coaxial Internet cable, hiki ke manaʻo ʻia nā poho hōʻailona e hiki mai ana.
- 20% nalowale hōʻailona ma 50 kapuaʻi
- 33% nalowale hōʻailona ma 100 kapuaʻi
Hiki iaʻu ke hoʻohana i kekahi uwea coaxial no ka pūnaewele
ʻAʻole, ʻaʻole hiki iā ʻoe ke hoʻohana i ke kaula coaxial no ka pūnaewele. Hoʻolālā ʻia kekahi o lākou e hoʻopili i ka lekiō a i ʻole ke kīwī, aʻo nā mea ʻē aʻe i hoʻolālā ʻia e hoʻouna i ka ʻikepili ma luna o ka Pūnaewele. No laila, pono ʻoe e kūʻai i ke kaula coaxial e kākoʻo ana i ka hoʻoili ʻikepili ma luna o ka Pūnaewele. ʻO nā kaula RG-6, RG-8 a me RG-58 nā kelepona pūnaewele coaxial maʻamau ma ka mākeke. (1)
He aha ke kū'ē i nā ohms o nā kaula coaxial no ka pūnaewele?
I ka hoʻokaʻawale ʻana i nā kelepona pūnaewele coaxial e pili ana i kā lākou impedance, ʻelua ʻano o nā kaula i ʻike ʻia; 50 ohm a me 75 ohm. Hoʻohana nui ʻia nā kaula 50 ohm no ke kamaʻilio kelepona a me ka lawe ʻana i ka ʻikepili. A hoʻohana ʻia nā kaula 75 ohm no nā hōʻailona wikiō. (2)
E nānā i kekahi o kā mākou ʻatikala ma lalo nei.
- Pehea e nānā ai i ka hōʻailona o ke kaula coaxial me kahi multimeter
- Kahi e loaʻa ai ka uwea keleawe mānoanoa no ka ʻōpala
- Pehea ka manoanoa o ka uwea anana 18
