Ahakoa te hono i ngā hapori, te horapa rānei i ngā whenua, ko te tere me te tika ngā whakaritenga matua e rua mō ngā whatunga muka whatu e kawe ana i ngā mahi whakawhitiwhiti kōrero nui. Me tere ake ngā hononga FTTH me ngā hononga pūkoro 5G a ngā kaiwhakamahi kia tutuki ai ngā tono rongoā-ā-ringa, waka motuhake, huihuinga ataata me ētahi atu tono whānui-rahi. Nā te putanga mai o te maha o ngā pokapū raraunga me te tere o te whanaketanga o te matauranga horihori me te ako mīhini, me ngā tere whatunga tere ake me te tautoko i te 800G me runga ake, kua noho ko ngā āhuatanga muka katoa he mea nui.
E ai ki te paerewa ITU-T G.650.3, me whakamahi te ine whakaata rohe wā whatu (OTDR), te taputapu whakamātautau ngaronga whatu (OLTS), te mararatanga chromatic (CD), me ngā whakamātautau mararatanga aratau polarization (PMD) hei mahi i te tautuhi muka whānui me te whakarite i te mahi whatunga teitei. Nō reira, ko te whakahaere i ngā uara CD te mea nui hei whakarite i te pono me te whai hua o te tuku.
Ahakoa he āhuatanga tūturu te CD o ngā muka whatu katoa, arā, ko te toronga o ngā pāoro whānui i ngā tawhiti roa, e ai ki te paerewa ITU-T G.650.3, ka noho te horapa hei raruraru mō ngā muka whatu me ngā tere tuku raraunga neke atu i te 10 Gbps. Ka pā kino te CD ki te kounga o te tohu, inā koa i roto i ngā pūnaha whakawhitiwhiti tere-tiketike, ā, ko te whakamātautau te mea nui ki te whakatika i tēnei wero.
He aha te CD?
Ina horapa ngā pāoro o ngā roangaru rerekē i roto i ngā muka whatu, ka taea e te mararatanga o te mārama te whakararuraru me te whakapōturi, ā, ka mutu, ka heke te kounga o te tohu e tukuna ana. E rua ngā momo mararatanga: te mararatanga rauemi me te mararatanga arataki ngaru.
He mea ā-roto te mararatanga o ngā rauemi i roto i ngā momo muka whatu katoa, ka taea e tēnei te whakaputa i ngā roangaru rerekē kia horapa i ngā tere rerekē, ā, ka mutu, ka tae atu ngā roangaru ki te kaitahuri mamao i ngā wā rerekē.
Ka puta te mararatanga o te arataki ngaru i roto i te hanganga arataki ngaru o ngā muka whatu, te wāhi e horapa ai ngā tohu whatu mā roto i te matua me te hipoki o ngā muka, he rerekē ngā taupū whakaata. Ka hua ake tēnei i te huringa o te diameter o te mara aratau me te rerekētanga o te tere tohu i ia roangaru.
He mea nui te pupuri i tētahi taumata o te CD hei karo i te putanga mai o ētahi atu pānga kore-raina, nō reira kāore i te tūtohutia te kore CD. Engari me whakahaere te CD i tētahi taumata e whakaaetia ana hei karo i ngā pānga kino ki te pono o te tohu me te kounga o te ratonga.
He aha te pānga o te momo muka ki te horapa?
E ai ki te kōrero i mua ake nei, he āhuatanga tūturu te CD o tētahi muka whatu, engari he mea nui te momo muka ki te whakahaere i te CD. Ka taea e ngā kaiwhakahaere whatunga te whiriwhiri i ngā muka marara "taiao" me ngā muka rānei me ngā ānau marara kua wehea hei whakaiti i te pānga o te CD i roto i tētahi awhe roangaru motuhake.
Ko te muka e whakamahia whānuitia ana i roto i ngā whatunga o ēnei rā ko te muka paerewa ITU-T G.652 me te marara taiao. Kāore te muka ITU-T G-653 kore marara e tautoko i te tuku DWDM, engari he iti ake te CD o te muka kore-kore marara G.655, engari kua arotauhia mō ngā tawhiti roa, ā, he nui ake te utu.
Hei whakamutunga, me mārama ngā kaiwhakahaere ki ngā momo muka whatu i roto i ā rātou whatunga. Mena ko te nuinga o ngā muka whatu he paerewa G.652, engari ko ētahi he momo muka kē atu, ki te kore e kitea ngā CD i roto i ngā hononga katoa, ka pāngia te kounga o te ratonga.
Hei whakamutunga
He wero tonu te horapa o te irahiko me aro atu kia mau tonu ai te pono me te whai huatanga o ngā pūnaha whakawhitiwhiti tere-teitei. Ko ngā āhuatanga muka me te whakamātautau he mea nui ki te whakaoti rapanga i te uaua o te horapa, e whakarato ana i te māramatanga mō ngā tohunga hangarau me ngā miihini ki te hoahoa, ki te whakatinana, me te pupuri i ngā hanganga e kawe ana i ngā whakawhitiwhitinga kaupapa nui o te ao. Mā te whanaketanga tonu me te whānui haere o te whatunga, ka haere tonu a Softel ki te auaha me te whakarewa i ngā otinga ki te mākete, hei ārahi i te huarahi ki te tautoko i te tango i ngā hangarau matatau.
