Te Mārama ki ngā Rohe Mate e Ngaro ana

Te Mārama ki ngā Rohe Mate e Ngaro ana Ka taea e ngā rohe mate te tinihanga ahakoa te hangarau matatau rawa atu. He wāhanga poto ēnei i muri tonu i te hononga, i te hononga rānei, ā, kāore e taea e te OTDR te kite i ngā takahanga takitahi.

Ka taea e tēnei rohe mate takahanga, i te nuinga o te wā i te 10–65 putu te tawhiti, te huna i ngā hapa tata. Mā te whakamahi i ngā muka whakarewa roa ake, tae atu ki te 350 putu, ka puta te hononga tuatahi mai i te rohe mate.

Mā tēnei huringa kotahi ka kitea te pūtake o te raruraru. He mea nui te kimi i ēnei rohe mate e ngaro ana i te wā e whakamārama ana i ngā tohu. Mā tēnei, e kore e ngaro i a koe tētahi hapa hononga, tētahi hononga rānei e piri ana i roto i te paru!

Te Whakatau i ngā Whakaaroaro "Kehua"

Te Whakahaere i ngā Whakaata "Kehua" Ka puta ngā whakaata kehua ina whakaatahia te mārama ki roto i te muka. Mā ēnei whakaata ka puta ngā kaupapa "kehua" ki tō whakaaturanga OTDR.

He tinihanga pea ēnei, nā te mea he rite tonu ki ngā hapa tūturu, engari kāore e pā ki ngā hapa ā-tinana. Hei whakaiti i te tūponotanga o te hanga i ngā mea ngaro, me whakarite kia ma, kia tika hoki te hononga o ngā hononga.

Mena he teitei te whakaata—arā, e tata ana ki te 0 dB—he tohu noa iho tēnei he hononga ngoikore kei te taha tata tonu. Ko te mārama ki te āhua o te puta mai o ngā kaupapa tūturu me ngā kaupapa wairua te mea nui kia kore ai koe e hē te whakamārama i tō tātaritanga.

Te Whakanui i te Tika o te Ine

Ko te whakatutuki i ngā tau pono mai i tētahi OTDR ka tīmata mā te whakatikatika me te whiriwhiri i te roanga ngaru tika mō tō muka. Ko ngā paerewa a te Hōia me te kāwanatanga o Amerika e whakahau ana kia whakamahia ngā muka whakarewa me te muka whiwhi.

Hei tāpiri atu ki tēnā, ka tūtohu rātou kia kaua e piko, kia kaua hoki e pēhia ngā taura, me te tirotiro i ngā hononga i mua i ia whakamātautau. Kaua e wareware ki ngā āhuatanga o te whakamātautau—ka puta he hua pai ake i roto i te taiao ma, he taiao whakahaeretia.

Te Whakamārama i ngā Raraunga Aroturuki Uaua

Ki te hunga kāore i te mōhio, he rite tonu te whakamataku o ngā tohu OTDR ki te pae maunga. Rapua ngā hikoinga mārama: te pūwāhi whakarewa, ngā hononga, ngā hononga, me te pito muka.

Ko ngā tauira—pērā i te pikinga ohorere, te hekenga rānei—tērā pea he tohu i te whati, i te piko koi rānei. Mā te whakamātau me te hapa, ka noho hei āhua noa te mārama ki ēnei tohu.

I mua i tō mōhio, kua kitea e koe ngā raruraru i mua i te hurihanga hei hapa nui.

Te Kōwhiri i tō OTDR Tino Pai

Ko te kimi i te OTDR tino tika tētahi o ngā mahi e tino rite ana ki te whiriwhiri i tētahi taputapu mō tētahi mahi motuhake—he mea nui ngā mea iti katoa!
