Pehea e hoʻohana ai ka Pūnaewele Pūnaewele Wired
ʻO Jack 45 ke kākauʻia (RJ45) heʻano maʻamau o ka pūnaewele kino no nā laina kelepona. RJ45 mauʻike i kaʻike nuiʻia me nā laina a Ethernet a me nā network.
Hiki i nāʻanuʻu Ethernet hou keʻano i nā puʻupuʻu kalaku liʻiliʻi ma kēlā me kēia hopena i hoʻokomoʻia i loko o nā kākika RJ45 o nā mea Ethernet. ʻO ka hua'ōlelo "plug" e pili ana i ke kele a iʻole ka "male" hopena o ka pūnaewele aʻo ka hua'ōlelo "jack" e pili ana i ke awa a iʻole ka "wahine" hopena.
RJ45, RJ45s, a me 8P8C
Aia nā wānanaʻo RJ45 iʻewalu mau piʻi e hiki ai i ke kaula kelepona o ke kelepona kelepona maʻamau. ʻO kēlā me kēia pūkowele he mau wahiʻewalu i hoʻolālāʻia he 1 mm i loko o kahi e hoʻokomoʻia ai nā wiwi hoʻokahi me ka hoʻohanaʻana i nā pono hana kaula kaula kaula. 8P8C,ʻokoʻa no kaʻEwalu Position,ʻEwalu Manawa).
ʻO nāʻanuʻu Ethernet a me 8P8C pūnaewele e komo i loko o ka hiʻohiʻona uila RJ45 e hana pono. ʻOihana, 8P8C hiki ke hoʻohanaʻia me nāʻano likeʻole me ka Ethernet; hoʻohana pūʻia me nā kaula maʻamau RS-232 , no ka laʻana. Eia naʻe, no ka mea, ma kahi mamao loa ka hoʻohanaʻana o RJ45 i ka 8P8C, hoʻohana mau nāʻoihanaʻoihana i nā hua'ōleloʻelua.
Ua hoʻohanaʻia nā modems -up modem i ka hoʻololiʻana o RJ45 i kapaʻiaʻo RJ45 , nona wale nō nā heluʻelua i ka hoʻonohonoho 8P2C ma kahi oʻewalu. ʻO ka pili likeʻana o RJ45 a me RJ45 he mea paʻakikī ia no ka nānāʻole i nā makaʻelua.
Nā Hoʻoponopono Pilikino o RJ45 Pūnaewele
ʻElua kūmole RJ45 kūlana e ho'ākāka i ka hoʻonohonohoʻana o kēlā me kēia kanakaʻewalu mauʻili i pono i ka wā e hoʻopaʻa ana i nā mea pili i ke kele:ʻo nā T568A a me T568B . E hahai ana lāua i kekahi papa hana o ka uhiʻana i nā wiwi hoʻokahi i loko o kaʻelima mau lelo-keʻokeʻo, ka'ōmaʻomaʻo, kaʻalani, kaʻulaʻula, a keʻokeʻo paha - me kahi hui pū me nā hui paʻa.
Ma muli o kēia mau papahana he mea nui ia i ka kūkuluʻana i nā kani e hoʻoikaika ai i ka pilina uila me nā meahana'ē aʻe. No nāʻike o ka wā i hala, ua lilo ka T568B i mea kūpono loa. ʻO ka papa ma lalo nei e hōʻuluʻulu ana i kēia hoʻopili kala.

ʻO kekahi mauʻano likeʻole e like me RJ45, a hiki ke maʻalahi i kekahi i kekahi. ʻO ka hui pūnaewele RJ11 i hoʻohanaʻia me nā laina kelepona, no ka laʻana, e hoʻohana i nā loulouʻeono ma kahi oʻewalu kūlana pūnaewele, e hōʻemi liʻiliʻi iā lākou ma mua o nā connectors RJ45.
Nā nīnau me RJ45
No ke kūkuluʻana i kahi pilina paʻa ma waena o ka poli a me ke kikowaena pūnaewele, ua hoʻohana kekahi mau pūnaewele RJ45 i kahi'āpana'ilika liʻiliʻi i kapaʻia he laha. Hoʻokumu ka papa i kahi sila ma waena o ke kaula a me kahi port i kahi hoʻokomoʻana, e koi ana i kahi kanaka e hoʻohana i kekahi pihi lalo ma luna o kaʻaha eʻae ai i ka wehe. Hiki ke kōkua i ka paleʻana i ke kaula mai ka wehe wale aku. ʻO ka mea pōʻino,ʻoluʻolu ka wāwahi o kēia mau pahu i ka wā i huli ai i hope, i ka manawa e pihi ai ke kaula i kekahi kī'ē aʻe,ʻaʻahu, a i kekahi mea'ē aʻe paha.
