Taura Cat5/5e, Cat6/6a, Cat7 me te Cat8: Te Aratohu Tino Pai

2025-02-26

Me whai aratohu tino pai ahau mō ngā taura Cat5/5e, Cat6/6a, Cat7, me Cat8. Ngā mea e mōhiotia ana e au mō ēnei kāwai. He rerekē ngā whakatakotoranga o ia tau Cat mō ngā taura Ethernet. He rerekē te tere, te whānui o te hononga, te ārai, me te tawhiti pea ka taea e rātou te tuku raraunga.

Tuatahi, me whakarārangi takitahi e au ia kāwai. Kia titiro tātou. He tawhito ake a Cat5, tae atu ki te 100 Mbps pea? Engari kua whakarei ake a Cat5e, e tautoko ana i te 1 Gbps. Kātahi ka taea e Cat6 te mahi i te 1 Gbps i ngā tawhiti roa, 10 Gbps pea engari he poto ake. Kua whakanuia a Cat6a, nō reira he pai ake te mahi, 10 Gbps pea i runga i te 100 mita. Kua tiakina a Cat7, he tere ake, engari he rerekē ngā hononga e whakamahia ana? Ā, ko Cat8 mō ngā pokapū raraunga, he tere tino teitei engari he tawhiti poto ake.

Taria, me tika ngā taipitopito. Me tirotiro e au taku mahara. Ko te tere o te Cat5e he 1 Gbps tae atu ki te 100 mita. Ka taea e te Cat6 te mahi i te 10 Gbps tae atu ki te 55 mita. Ka toro atu te Cat6a ki te 100 mita mō te 10 Gbps. Ko te whakatauranga o te Cat7 he 10 Gbps tae atu ki te 100 mita me ngā auau teitei ake pea. Kua hangaia te Cat8 mō te 25, 40 Gbps rānei tae atu ki te 30 mita. Waihoki, he mea nui te parenga; he nui ake ngā parenga o ngā kāwai teitei ake hei whakaiti i te pokanoa.

Me kōrero anō hoki ahau mō ngā rerekētanga hanga, pērā i te UTP (unshielded twisted pair) me te STP (he mea ārai). Ko te Cat5e he UTP i te nuinga o te wā, ko te Cat6a me runga ake ka whakamahi pea i te ārai. Ka whakamahi a Cat7 i ngā hononga GG45, i te TERA rānei, engari he hototahi tonu ki te RJ45. Taria, he tika tēnā? Tērā pea ka whakamahi a Cat7 i te RJ45 engari he nui ake te ārai. He pono ka whakamahi a Cat8 i te RJ45.

He mea nui anō hoki ngā tono. Hei tauira, ko te Cat5e mō ngā whatunga kāinga, ko te Cat6 mō ngā tari, ko te Cat7 mō ngā ahumahi, me te Cat8 mō ngā pokapū raraunga. Ko te utu tētahi atu āhuatanga; he nui ake te utu mō ngā kāwai teitei ake. Tērā pea he mea whakaaro ki te tiaki i te heke mai. Waihoki, ko te roa o te taura me te mea he matua totoka, he matua kua herea rānei. Āe, tika, ko te matua totoka mō ngā tāutanga pumau, ko te matua kua herea mō ngā taura papaki.

Me whakarite e au te aratohu me ngā wāhanga mō ia momo taura, ngā whakatakotoranga matua (tere, whānui, tawhiti), te parepare, ngā tono, me tētahi tūtohi whakatairite. Kātahi ka tāpirihia ngā whakaaro hoko pēnei i ngā hiahia tono, te ārai i te heke mai, te tahua, te taiao (te pokanoa haruru), me te momo tāutanga (totoka, taura rānei).

Taria, me tirotiro anō e au ngā tere me ngā tawhiti mōrahi. Kia manatoko ahau: Ko te Cat5e he 1 Gbps i te 100 MHz i runga i te 100m. Ko te Cat6 he 1 Gbps tae atu ki te 100m, 10 Gbps tae atu ki te 55m. Ko te Cat6a he 10 Gbps i te 500 MHz i runga i te 100m. Ko te Cat7 he 10 Gbps i te 600 MHz i runga i te 100m, me te Cat7a tae atu ki te 1000 MHz. Ko te Cat8 he 25/40 Gbps i te 2000 MHz tae atu ki te 30m. Waihoki, he tino kaha ake ngā whakaritenga tiaki mō te Cat7 me te 8.

He mea nui te tāpiri i te whānui o te hononga (MHz) nā te mea ka pā tēnei ki te kaha tuku raraunga. Ngā hononga: Ka whakamahia e te Cat8 te RJ45, engari he rerekē pea ngā momo parenga o ngā Cat o mua. Waihoki, ko te hototahi ki ngā hanganga o nāianei. Hei tauira, ko te whakamahi i te Cat6a me ngā hononga Cat5e, kāore pea e whakamahi i te pūmanawa katoa.

Me kī atu au ko ngā kāwai teitei ake ka tautoko i ngā whānui whānui teitei ake, nō reira he pai ake mō ngā whatunga tere-nui, engari he nui rawa pea mō te whakamahinga taketake. Waihoki, ko ngā rerekētanga ā-tinana pērā i te matotoru me te whānui piko. He matotoru ake te Cat6a, ā, he iti ake te ngāwari i te Cat5e.

I roto i ngā whakaaro mō te hoko, ka whakaarohia ngā āhuatanga pēnei i ngā hiahia o nāianei me ngā hiahia ā muri ake nei, te taiao (ahumahi me te pokanoa me te kāinga), me te hiahia rānei rātou ki te PoE (Mana i runga i te Ethernet), ko ēhea wāhanga teitei ake ka pai ake te tautoko.

Me whakarite kia ngāwari te mārama ki te aratohu, kia kore ai e nui rawa ngā kupu hangarau, engari kia whai kōrero tonu. He ripanga whakarāpopototanga poto pea i te tīmatanga, kātahi ka tāpirihia ngā wāhanga taipitopito. Me ngā whakamahinga noa hoki hei āwhina i ngā kaipānui ki te whakatau ko tēhea e hiahiatia ana e rātou.

Taria, me tirotiro e au mēnā kei te mōhiotia te Cat7 e ngā paerewa TIA/EIA, mēnā rānei he paerewa ISO. Nā te mea i ētahi wā kāore te Cat7 i te tino whānuitia te whakamahi i roto i ētahi rohe. He paerewa ake te Cat6a me te Cat8. He mea pea tēnei hei whakaaroaro māu, pērā i te hototahi ki ngā paerewa o nāianei.

Me ngā rerekētanga utu anō hoki. Ko te Cat5e te mea iti rawa te utu, ko te Cat6, Cat6a, Cat7, Cat8 te mea tino utu nui. Nō reira, he mea nui te tahua. Mō te nuinga o ngā kaiwhakamahi kāinga, he rawaka te Cat5e, te Cat6 rānei. Mō ngā kāinga atamai he maha ngā taputapu, ko te Cat6 pea. Mō ngā pokapū raraunga, ko te Cat8.

Tērā pea he raruraru te whenua o ngā taura ārai; ki te kore e tika te whenua, ka raru pea te ārai. Nō reira, me tika ngā tikanga mō te tāutanga o ngā taura ārai.

Hei whakarāpopototanga, me kapi i te aratohu ngā āhuatanga o ia momo taura, me whakatairite, me te ārahi i te kaipānui i runga i ō rātou hiahia motuhake: ngā whakaritenga tere, te tawhiti, te taiao, te tahua, me ngā mahere ā meake nei.

Te āraiE hiahiatia ana i ngā taiao haruru engari me tika te whakatū whenua.
Ngā PaerewaE mōhiotia ana a Cat6a me Cat8 e te TIA/EIA; e whai ana a Cat7 i te ISO.
Tautoko PoEKa tautokohia e ngā kāwai katoa te PoE, engari he pai ake te whakahaere i te wera e ngā taumata teitei ake.

Kōwhiria i runga i ō hiahia o nāianei, me te whakaaro anō hoki ki ngā whakapainga ā muri ake nei. He maha ngā whare ka ora pai me te Cat6, engari ko ngā umanga me aro ki te Cat6a, ki te Cat8 rānei.
