RJ45

RJ45 - Registered Jack 45 - E kiia ana hoki he taura Ethernet. Ka taea te RJ45 te hāngai, te whakawhiti rānei i runga anō i tōna whakamahinga. Ka whai ōna tūhononga i ngā waehere tae pū.

Ko te paerewa taura e āhei ai ngā tūhononga whatunga hei tauira Ipurangi mā tētahi pouaka.
E 8 ngā pine o ngā tūhononga hiko o tēnei momo taura. E kiia ana hoki ko te taura ETHERNET e kiia ana tōna tūhono ko te tūhono 8P8C (e 8 ngā tūnga me ngā hoapā hiko e 8).

He hototahi ā-tinana tēnei tūhono ki te tūhono RJ11
RJ11
RJ11 - Registered Jack 11 - Ka whakamahia mo te waea rārangi whenua. He paerewa aowhānui tērā e whakamahia ana hei tūhono i te waea raina whenua ki te whatunga waea waea. Ka whakamahi te RJ11 i tētahi tūhono 6-slot. Kei roto i a RJ11 e 6 ngā kāniwha (tūnga) me ngā pūkawe e rua, kua tuhia te paerewa 6P2C.
Ka taea te mamati(DSL), te tairitenga rānei te mōhiohio i tukuna ki te raina.
mēnā ka whakamahia he whāurutau.
Kei te cabling rorohiko RJ45 I te 10/100 Mbit/s, e 4 anake ngā pine 1-2 me te 3-6 ka whakamahia hei tuku mōhiohio.
I te tau 1000 Mpps (1Gbps) o te tarenga, ka whakamahia ngā pine 8 o te socket.
Ngā paerewa cabling e rua RJ45 ko te nuinga o te wā ka whakamahia ki ngā turanga waea : ko te paerewa T568A me te paerewa T568B.
He tino ōrite ēnei paerewa : ko ngā takirua anake 2 (ārani, karaka mā) me te huringa 3 (kākāriki, kākāriki-mā).

Ngā waehere tae

Ka whakamahia e te mahi rorohiko nga tikanga waehere takawaenga. Mā ēnei arowhānui ka taea e ngā kaihangarau te matapae me pēhea te whakamutunga o te taura Itarangi i ngā mutunga e rua kia taea ai te whakangāwari i te mahi a ngā kaihangarau, ka taea te mōhio ki te taumahi me ngā tūhononga o ia takirua o ngā aho.
E whai ana te taura taura itarangi cabling i ngā paerewa T568A me T568B.

Kāore he rerekētanga hiko i waenganui i ngā aho rerekē T568A me T568B, e kore hoki e pai ake i tētahi. Ko te rerekētanga anake i waenganui i aua wā ka whakamahia ki tētahi rohe, momo whakahaere rānei.
Nā reira, ko tō kōwhiringa waehere tae ka tino āhua tonu ki te whenua e mahi ai koe me ngā momo whakahaere ka tāutahia e koe.

RJ45 matau

Te taura matau (kua tohua PATCH CABLE rānei STRAIGHT-THROUGH CABLE ) ka whakamahia hei tūhono i tētahi pūrere ki tētahi pokapū whatunga, whakawhiti whatunga rānei. Kua honoa ngā aho ki tētahi raina hāngai ki ngā tūhono e 2, ōrite ana te aho i runga i te hoapā ōrite.

RJ45 i rīpeka

Te taura whakawhiti (kua tohua CROSSOVER CABLE i roto i tōna tāpae) kei te whakamahia hei hono i ngā pūtahi e rua, i ngā whakawhiti whatunga rānei, i waenganui i tētahi o ngā tauranga pūnoa (MDI) nui ake te kaha, me te tauranga pāhekoheko MDI-X o te kaha o raro e hiahia ana ki te tiri i te hōkaiipurangi o te utauta whatunga pārongo.

Ngā Paerewa T568A me T568B

Ko te rerekētanga anake te tūnga o nga takirua kākāriki me te karaka. Engari i tua atu i tēnei whakarato, e rua, e toru rānei ētahi atu take hototahitanga ka taea hoki te rerekē. Hei te rā, T568A Kua whakahōutia te nuinga o te arowhānui e te paerewa T568B. Ka ōrite tēnei ki te waehere tae tawhito o te paerewa 258A d'AT&T (Te kamupene Amerika) me te wā kotahi e whakanoho ana i nga hiahia o nāianei me nga hiahia o muri atu. Hei tāpiri atu T568B he hototahi hoki ki te Te Tari Paerewa o U.S. (USOC), ahakoa mo tētahi takirua anake. Kātahi anō ka T568B ko te nuinga o te wā ka whakamahia i roto i ngā pānga arumoni, i te wā T568A he taunga kē a ia i roto i nga toi o te kāinga.

Ka taea te mōhiotia ki te pānga o ngā taura tōtika roa e hokona, kua tūaritia kētia rānei ki runga i te mākete, he hototahi ngā paerewa e rua ki a rāua, i te mea kāore te tae kōwhiringa e huri i ngā āhuatanga ā-autō o ia takirua whiriwhiri.

T568A

T568A est la norme majoritaire suivie pour les particuliers dans les pays d'Europe et du Pacifique. Il est également utilisé dans toutes les installations du gouvernement des États-Unis.

Te taura whakawhiti (kua tohua CROSSOVER CABLE ) i te nuinga o te wā hei tūhono i ngā pokapū whatunga, ngā whakakā rānei e rua.
Ko ngā takirua 2 me te 3 e rīpeka ana kia ōrite te pākokitanga. Kua rīpekatia hoki ngā takirua 1 me te 4, engari me tēnei anō, ko ngā aho e whakarewa ana i ēnei takirua ka whakawhititia hoki, nā reira he rerekētanga o te pitorua.

Ngā taura Cat5, Cat6 me Cat7 ko te RJ45 te mea tino whakamahia.
Ngā taura Cat5, Cat6 me Cat7 ko te RJ45 te mea tino whakamahia.

Ngā momo taura RJ45

Karangatia he taura Itarangi. Ko ngā taura i karangatia Cat5, Cat6 me Cat7 ko ngā taura RJ45 tino whakamahia i roto i ngā tūhononga whatunga o nāianei.
E 6 ngā kāwai o ngā aho RJ45 o te tarenga. Mō tētahi whatunga tūmataiti he taura RJ45 he nui te kāwai 5. Mō ngā whatunga nui ake, he taura RJ45 kāwai teitei ake (5E, 6 rānei).




Cat5 vs Cat5e

I hoahoatia tuatahitia te kāwai 5 hei tuku i ngā auautanga o te 100 MHz, e tuku ana i tētahi tere raina ingoa o te 100 Mbit/s. Cat 5 ka whakamahia e rua ngā takirua whiriwhiri (e whā hoapā) me te awhe mōrahi 100 mita. He tauwhāititanga Cate5e kātahi ka whakaurua ki nga whakaritenga me ngā paerewa pākaha. E hiahiatia ana hoki e te paerewa hōu he taura hou kia whakaurua ai nga takirua whiriwhiri e whā.

Mō ngā tawhiti poto, i raro i ngā here tohu pai, ā, kei te whakaaro e whā ngā takirua, ngā taura tūhono Cat5 et Cat5e Ka taea e te tare i te tere o Gigabit Ethernet.
Ka whakamahi a Gigabit Ethernet i tētahi aronui whakawaehere arotau kua hoahoatia kia whakahaere i roto i ēnei tohu tūtohu hahaka iho.

Cat6 vs Cat6a

He hototahi hoki whakamuri ki Cat5e, He pākaha ngā paerewa o te kāwai 6, ā, he tino pai ake te whakataetae ākau. Te taura Cat6 I hoahoatia a hei paerewa mō Gigabit Ethernet, e tuku ana i ngā tere māori tae atu ki te 1000 Mpps i te auautanga o te 250 MHz. Mā te whakaiti i te tawhiti taura mōrahi mai i te 100 mita ki te 55 ine, e tautokona ana 10 Kipaiti Ethernet.

Cat6a tauruatia te auautanga ki te 500 MHz i a koe e haere tonu ana ki te whakaiti whakaiti i te whakararutanga oro ki te pepa whakangungu tūāpapa. Mā ēnei whakareitanga e tango i te whiu tawhiti taura ina whakahaere i roto i te 10 Gigabit Ethernet.
Ka whakahaere hei te tere whakatauranga o te 10 Gigabit, ā, neke atu rānei i te 600MHz
Ka whakahaere hei te tere whakatauranga o te 10 Gigabit, ā, neke atu rānei i te 600MHz

Kāwai 7

Whakahaere ana i ngā auautanga tae atu ki te 600 MHz, Cat7 Kua hoahoatia a kia tautoko i te 10 tere whakatauranga a Gigabit Ethernet. I tua atu i te whakangungu whakangungu nā Cat6e, mā tēnei whakaritenga hou e whakangungu ia whakangungu mo ia takirua whiriwhiri e whā.
Cat7 e 100 ine ana te tawhiti mōrahi me te pupuri i te hototahi whakamuri ki Cat5 me Cat6. Cat7a ka whakanui ake i te auautanga ki te 1000 MHz, mā te whakarato i te whakaritenga nui ake e taea ai te tautoko i ngā tere Itarangi 40/100 Gigabit ā muri ake. Mā te pikinga ki te 1000 MHz ka whakaae hoki i te tarenga o ngā roma PW taura auau.
