Taura muka whatu aratau kotahimetaura muka whatu maha-aratauHe rerekē ngā mahi a ēnei taura, ā, kāore e taea te whakamahi hei whakawhiti. Ka pāngia te mahi a ngā rerekētanga pēnei i te rahi matua, te pūtake mārama, me te whānuitanga tuku. Hei tauira, ka whakamahia e te taura muka whatu maha-aratau ngā rama LED, ngā rama taiaho rānei, engari ko te taura muka whatu aratau kotahi ka whakamahia ngā rama taiaho anake, kia tika ai te tuku tohu i ngā tawhiti roa i roto i ngā tono pēnei i tetaura muka whatu mō te waea pūkorometaura muka whatu mō te FTTH. Mā te whakamahinga hē ka heke te tohu, ka kore pumau te whatunga, ka piki ake hoki ngā utu. Mō te mahi tino pai i roto i ngā taiao pēnei itaura muka whatu mō te pokapū raraungangā tono, he mea nui te whiriwhiri i te taura muka whatu tika.
Ngā Whakaaro Matua
- Ka whakamahia ngā taura aratau-kotahi me ngā taura aratau-maha mōngā mahi rerekēKāore e taea te whakawhiti. Kōwhiria te mea tika mō ō hiahia.
- He pai te mahi a ngā taura aratau-kotahi mōngā tawhiti roame ngā tere raraunga teitei. He tino pai mō ngā pokapū waea me ngā pokapū raraunga.
- He iti ake te utu mō ngā taura maha-aratau i te tīmatanga, engari ka nui ake pea te utu i muri mai. Nā te mea he poto ake te tawhiti e mahi ai, ā, he iti ake te tere raraunga.
Ngā Rerekētanga Hangarau i waenga i ngā Taura Aratau-Maha me ngā Taura Aratau-Kotahi
Te Diameter Matua me te Pūtake Mārama
Ko te whānui o te pūtake he rerekētanga matua i waenga i tetaura aratau-maha me te aratau-kotahi. Ko ngā taura maha-aratau he nui ake te diameter matua, mai i te 50µm ki te 62.5µm, i runga i te momo (hei tauira, OM1, OM2, OM3, OM4 rānei). He rerekē, ko te diameter matua o te taura muka whatu aratau kotahi he iti ake, tata ki te 9µm. Ka pā tika tēnei rerekētanga ki te momo pūtake mārama e whakamahia ana. Ka whakawhirinaki ngā taura maha-aratau ki ngā LED, ki ngā taiaho taiaho rānei, ko ngā taura aratau kotahi ia ka whakamahi i ngā taiaho taiaho anake mō te tuku mārama tika me te arotahi.
| Momo Taura | Te Diameter o te Matua (microns) | Momo Pūtake Mārama |
|---|---|---|
| Aratau Maha (OM1) | 62.5 | LED |
| Aratau Maha (OM2) | 50 | LED |

Te Tawhiti Tuku me te Whānuitanga o te Aratuku
He tino pai ngā taura aratau-kotahi ki te tuku raraunga tawhiti me te kaha o te whānui. Ka taea e rātou te tuku raraunga i ngā tawhiti tae atu ki te 200 kiromita me te whānui mutunga kore. I tētahi atu taha, ka herea ngā taura aratau-maha ki ngā tawhiti poto ake, i waenga i te 300 me te 550 mita, i runga i te momo taura. Hei tauira, ka tautoko ngā taura aratau-maha OM4 i ngā tere o te 100Gbps i te tawhiti mōrahi o te 550 mita.
| Momo Taura | Tawhiti Mōrahi | Whānuitanga o te arai |
|---|---|---|
| Aratau-Kotahi | 200 kiromita | 100,000 GHz |
| Aratau Maha (OM4) | 550 mita | 1 GHz |
Nā tēnei ka waiho te taura muka whatu aratau kotahi hei whiringa pai mō ngā tono e hiahia ana ki te tuku raraunga tere-nui mō ngā tawhiti roa.
Kounga Tohu me te Whakaiti
He rerekē rawa te kounga o te tohu me te whakaiti i te kaha o te tuku i waenga i ēnei momo taura e rua. Ka mau tonu te pumau o te tohu i ngā tawhiti roa nā te iti o te horapa o te momo taura. Ko ngā taura maha-aratau, me te rahi o te matua, ka nui ake te horapa o te momo taura, ka taea te whakaiti i te kounga o te tohu i ngā awhe roa.
| Momo muka | Te Diameter o te Matua (microns) | Awhe Whai Hua (mita) | Tere Tuku (Gbps) | Pānga Marara Aratau |
|---|---|---|---|---|
| Aratau-kotahi | 8 ki te 10 | > 40,000 | > 100 | Iti |
| Aratau-maha | 50 ki te 62.5 | 300 – 2,000 | 10 | Teitei |
Mō ngā taiao e hiahia ana ki te kounga tohu pumau, pono hoki, he painga nui te taura muka whatu aratau kotahi.
Ngā Whakaaro Whaihua mō te Kōwhiri i te Taura Tika
Ngā Rerekētanga Utu i waenga i ngā Taura Aratau-Maha me ngā Taura Aratau-Kotahi
He mea nui te utu ina whiriwhiria ana ngā taura aratau-maha me ngā taura aratau-kotahi. Ko ngā taura aratau-maha he iti ake te utu i te tīmatanga nā te mea he māmā ake te tukanga hanga me te whakamahinga o ngā transceiver iti ake te utu. Nā tēnei ka rongonui rātou mō ngā tono tawhiti poto, pērā i roto i ngā pokapū raraunga, i ngā whatunga puni rānei. Heoi, ahakoa he nui ake te utu i te tīmatanga, he pai te utu mō te taura muka whatu aratau-kotahi. Nā tōna kaha ki te tautoko i te whānui o te hononga me ngā tawhiti roa ake ka whakaiti i te hiahia mō ngā whakapainga auau, ngā haumitanga hanganga tāpiri rānei.

Ngā Whakamahinga o te Taura Muka Whatu Aratau Kotahi me ngā Taura Aratau Maha
He rerekē ngā whakamahinga o ēnei taura i runga i ō rātou āheinga hangarau. He pai ngā taura muka whatu aratau kotahi mō te whakawhitiwhiti tawhiti, pērā i ngā whakawhitiwhiti kōrero me ngā pokapū raraunga tere-teitei. Ka pupuri tonu i te pono o te tohu tae atu ki te 200 kiromita, ā, he pai mō ngā whatunga tuara me ngā tono whānui-rahi. I tētahi atu taha,ngā taura maha-aratau, inā koa ngā momo OM3 me OM4, kua arotauhia mō te whakamahinga tawhiti poto. He mea whakamahi noa ēnei i roto i ngā whatunga tūmataiti me ngā pokapū raraunga, e tautoko ana i ngā tere raraunga tae atu ki te 10Gbps i ngā tawhiti taurite. Nā te whānui o te matua ka taea te tuku raraunga whai hua i roto i ngā taiao kāore e hiahiatia he mahi tawhiti roa.
Te Hototahi ki ngā Hanganga Whatunga o nāianei
Ko te hototahitanga ki ngā hanganga o nāianei tētahi atu āhuatanga nui. He maha ngā wā ka whakamahia ngā taura maha-aratau i roto i ngā pūnaha tawhito e hiahiatia ana ngā whakahoutanga utu-pai. Nā te hototahitanga ki ngā transceivers me ngā taputapu tawhito, he mea whai hua ēnei hei whiriwhiri mā te pupuri i ngā whatunga o nāianei. Heoi, he pai ake te taura muka whatu aratau kotahi mō ngā whatunga hou, mahi-teitei. Nā tōna kaha ki te whakauru ki ngā transceivers matatau me te tautoko i ngā tere raraunga teitei ake, ka pai te mahi i roto i ngā taiao hou. I te wā e whakahou ana, e whakawhiti ana rānei, me arotake e ngā whakahaere ā rātou hanganga o nāianei kia mōhio ai ko tēhea momo taura e hangai ana ki ā rātou whāinga whakahaere.
Te Whakawhiti, te Whakapai Ake rānei i waenga i te Aratau Maha me te Aratau Kotahi
Te Whakamahi i ngā Whakawhitiwhiti mō te Hototahi
He mea nui te mahi a ngā kaiwhakawhitiwhiti ki te hono i te āputa i waenga i ngā taura aratau-maha me te aratau-kotahi. Ka hurihia e ēnei taputapu ngā tohu hei whakarite i te hototahitanga i waenga i ngā momo muka rerekē, ka taea ai te whakawhitiwhiti kōrero maeneene i roto i ngā whatunga ranu. Hei tauira, ko ngā kaiwhakawhitiwhiti pēnei i te SFP, SFP+, me te QSFP28 he rerekē ngā tere whakawhiti raraunga, mai i te 1 Gbps ki te 100 Gbps, e pai ai mō ngā tono pēnei i ngā LAN, ngā pokapū raraunga, me te rorohiko mahi-teitei.
| Momo Pūwhakawhiti | Te Tere Whakawhiti Raraunga | Ngā tono noa |
|---|---|---|
| SFP | 1 Gbps | Ngā LAN, ngā whatunga rokiroki |
| SFP+ | 10 Gbps | Ngā pokapū raraunga, ngā pāmu tūmau, ngā SAN |
| SFP28 | Tae atu ki te 28 Gbps | Rorohiko kapua, marikotanga |
| QSFP28 | Tae atu ki te 100 Gbps | Rorohiko mahi-teitei, pokapū raraunga |
Mā te whiriwhiri i te taputapu whakawhiti raraunga e tika ana, ka taea e ngā whakahaere te whakapai ake i te mahi a te whatunga me te pupuri tonu i te hototahitanga i waenga i ngā momo taura.
Ngā horopaki e taea ai ngā whakapai ake
Te whakapai ake mai i te aratau mahaKo te whakawhiti ki ngā taura aratau-kotahi he mea nui tonu nā te hiahia kia nui ake te whānui o te hononga me te roa o te tawhiti tuku. Heoi, he wero kei roto i tēnei whakawhiti, tae atu ki ngā here hangarau me ngā pānga pūtea. Tērā pea ka hiahiatia ngā mahi ā-iwi, pērā i te tāuta i ngā paipa hou, ka tāpiri atu ki te utu whānui. Hei tāpiri, me whai whakaaro ki ngā hononga me ngā papaki i te wā o te tukanga whakahou.
