Hei whakarite i ngā āhuatanga tono o ngā tohu tuku whatu tawhiti me te iti o te ngaronga, me tutuki i te taura muka whatu ētahi āhuatanga taiao ā-tinana. Mā te piko iti, te poke rānei o ngā taura whatu ka ngoikore ngā tohu whatu, ka mutu pea te whakawhitiwhiti kōrero.
1. Te roa o te raina ara taura muka whatu
Nā ngā āhuatanga ā-tinana o ngā taura whatu me te kore taurite o te tukanga whakaputa, ka horapa tonu, ka mimiti haere ngā tohu whatu e horahia ana i roto. Ina roa rawa te hononga taura muka whatu, ka nui ake te ngoikore o te tohu whatu o te hononga katoa i ngā whakaritenga o te whakamahere whatunga. Mēnā he nui rawa te ngoikore o te tohu whatu, ka whakaitihia te pānga whakawhitiwhiti kōrero.
2. He nui rawa te koki piko o te whakatakotoranga o te taura whatu
Ko te whakaiti piko me te whakaiti pēhanga o ngā taura whatu i puta mai i te whakarerekētanga o ngā taura whatu, ā, ka kore e taea te whakatutuki i te whakaata katoa i te wā e tukuna ana te whatu. He taumata piko anō ō ngā taura muka whatu, engari ina piko te taura muka whatu ki tētahi koki, ka rerekē te ahunga horapa o te tohu whatu i roto i te taura, ka hua ake te whakaiti piko. Me aro nui ki te waiho i ngā koki e ranea ana mō te waea i te wā e hangaia ana.
3. Kua pēhia, kua whati rānei te taura muka whatu
Koinei te hapa tino kitea i roto i ngā rahunga o ngā taura whatu. Nā ngā kaha o waho, ngā āhuatanga taiao rānei, ka pāngia pea ngā muka whatu e ngā piko iti, e ngā whati rānei. Ina pakaru i roto i te pouaka honohono, i te taura whatu rānei, kāore e kitea mai i waho. Heoi, i te wāhi e whati ai te muka, ka rerekē te taupū whakaata, ka ngaro hoki te whakaata, ka heke te kounga o te tohu tuku o te muka. I tēnei wā, whakamahia he taputapu whakamātautau taura whatu OTDR hei kite i te tihi whakaata me te kimi i te piko ā-roto, te pūwāhi whati rānei o te muka whatu.
4. Te rahunga o te hanganga hononga muka whatu
I roto i te tukanga whakatakoto taura whatu, he maha ngā wā ka whakamahia ngā hononga honohono muka whatu hei whakakotahi i ngā wāhanga e rua o ngā muka whatu ki te kotahi. Nā te hononga honohono o te muka karāhe i roto i te paparanga matua o te taura whatu, me whakamahi tika te hononga honohono kia rite ki te momo taura whatu i te wā o te tukanga honohono honohono o te papa hanga. Nā te korenga o te mahi e tutuki i ngā whakaritenga hanga me ngā huringa o te taiao hanga, he ngāwari te poke o te muka whatu ki te paru, ka hua ake he poke i roto i te tukanga honohono honohono, ā, ka heke te kounga whakawhitiwhiti o te hononga katoa.
5. Ka rerekē te diameter o te waea matua muka
He maha ngā tikanga hononga hohe e whakamahia ana i roto i te whakatakotoranga taura muka whatu, pērā i ngā hononga flange, e whakamahia whānuitia ana i roto i te whakatakotoranga whatunga rorohiko i roto i ngā whare. He iti noa ngā mate o ngā hononga hohe, engari ki te kore e ma te mata pito o te muka whatu, o te flange rānei i te wā e hono ana, he rerekē te diameter o te muka whatu matua, ā, kāore i te piri te hononga, ka nui ake te mate hononga. Mā te OTDR, te whakamātautau mana pito rua rānei, ka taea te kite i ngā hapa kore taurite diameter matua. Me mōhio he rerekē rawa ngā momo tuku, ngā roangaru, me ngā momo whakaiti i waenga i te muka aratau kotahi me te muka aratau maha, engari ko te diameter o te muka matua, nō reira kāore e taea te whakaranu.
6. Te poke o te hononga muka whatu
Ko te poke o te hononga o te muka hiku me te makuku e pekepeke ana i te muka ngā tino take o te pakaru o ngā taura whatu. Ina koa i roto i ngā whatunga o roto, he maha ngā muka poto me ngā momo taputapu whakawhiti whatunga, ā, he maha tonu te whakaurunga me te tango i ngā hononga muka whatu, te whakakapinga flange, me te whakawhiti. I te wā o te mahi, ka taea e te puehu nui, te ngaronga whakaurunga me te tango, me te pā o te maihao te hanga i te hononga muka whatu kia paru, ka kore e taea te whakarite i te ara whatu, te whakaiti rānei i te mārama. Me whakamahi he ūkui waipiro hei horoi.
7. Te oro ngoikore i te hononga
Ko te koretake o te oro o ngā hononga tētahi o ngā hapa matua o ngā hononga muka whatu. Kāore te whiti whakawhiti muka whatu tino pai e kitea ana i roto i te taiao tūturu, ā, he piko, he pari rānei. Ina tūtaki te mārama i roto i te hononga taura whatu ki tētahi whiti whakawhiti pēnei, ka puta te marara me te whakaata o te mārama i te mata hononga koretake, ka nui ake te whakaiti o te mārama. I te piko o te whakamātautau OTDR, he nui ake te rohe whakaiti o te wāhanga kāore i oro pai i tērā o te mata pito noa.
Ko ngā hapa e pā ana ki te muka whatu ngā hapa e kitea nuitia ana, e kitea whānuitia ana hoki i te wā e whakatikatika ana, e tiaki ana rānei. Nō reira, me whai taputapu hei tirotiro mēnā he noa te tukunga mārama muka whatu. Me whakamahi i ngā taputapu tātari hapa muka whatu mō tēnei, pērā i ngā mita mana whatu me ngā pene rama whero. Ka whakamahia ngā mita mana whatu hei whakamātautau i ngā ngaronga tuku muka whatu, ā, he tino ngāwari ki te whakamahi, he māmā hoki, he ngāwari hoki ki te whakamahi, koia te mea pai rawa atu mō te rapu i ngā hapa muka whatu. Ka whakamahia te pene rama whero hei kimi i te kōpae muka whatu kei runga te muka whatu. Ko ēnei taputapu nui e rua hei rapu i ngā hapa muka whatu, engari i nāianei kua whakakotahihia te mita mana whatu me te pene rama whero hei taputapu kotahi, he mea watea ake.
