Te Kimi, te Tauwāhi, me te Whakahaere i ngā Pūwāhi Whakaiti-Tiketike i roto i ngā Taura Whatu

I roto i te hanganga taura whatu, he inenga aromatawai nui te mahi whakaitiiti. I runga i ngā āhuatanga raina tikanga, ka tātarihia e tēnei tuhinga ngā tauwāhi me ngā tikanga whakahaere o ngā pūwāhi whakaitiiti teitei i roto i ngā raina taura whatu.

I. Ngā Wāhi Noa o ngā Pūwāhi Whakaiti-Tiketike

I muri i te otinga o te honohono taura, ka whakahaerehia te whakamātautau OTDR ki te wāhanga katoa o te whakawhiti. Mā tēnei whakamātautau ka manatoko mēnā ka tutuki ngā āhuatanga whatu o te taura honohono i ngā whakaritenga hanga me ngā paerewa whakaae. Ko te aromatawai ko:

• Mehemea he iti iho te whakaiti katoa o te wāhanga whakawhiti i te whakatakotoranga hoahoa (arā, mehemea e tutuki ana te tauwehenga whakaiti toharite i ngā whakaritenga)

• Mehemea e tutuki ana te ngaronga hononga toharite rua-ara o ngā hononga i ngā paerewa whakaae me ngā whakaritenga hoahoa

• Mehemea he ōrite, he maeneene hoki te pari o te pihi whakamuri, kāore he hikoinga whakaiti nui engari ko ngā hikoinga iti i puta mai i ngā ngaronga hononga noa.

Ina whakamahia he OTDR hei whakamātautau i te wāhanga whakawhiti me te kimi i ngā pūwāhi whakaiti-teitei, he mea nui kia tika te whakatakoto i ngā tawhā pēnei i te awhe, te roangaru, te whānui o te pāorooro, te taupū whakaata, me te wā toharite:

• Awhe whakamātautau:Whakatakotoria kia rite ki te roa o te wāhanga whakawhiti kia nohoia e te pihi te 2/3 o te mata whakaatu.

• Roanga ngaru:Ko te tikanga he 1310 nm me te 1550 nm mō ngā taura pūrua tawhiti

• Taupū whakaata:I whakatakotoria i runga i ngā whakaritenga a te kaihanga muka

• Whānui o te pātere:He tawhā matua—ki te iti rawa ka kore e ranea te whānuitanga hihiri me ngā pihi haruru; ki te nui rawa ka whakaiti i te tika o te ine. Me whiriwhiri i runga i ngā whakaritenga tawhiti me te tika.

• Te wā toharite:Whakatikatikahia kia maeneene te hiku piko, kia kore ai e kitea he haruru

Hei kimi tika i ngā pūwāhi hapa, ka taea te whakamahi i te pūmanawa tātari OTDR. E rua ngā wāhanga o ngā hapa: ngā hapa pouaka-hono me ngā hapa tinana-taura.

II. Te Whakahaere i ngā Pūwāhi Whakaiti-Tiketike

Tuatahi, whakatauhia mēnā kei te wāhi honohono te pūwāhi whakaiti-teitei. I ngā pūwāhi honohono, ka whakaatuhia e ngā muka katoa ngā hikoinga whakaiti o ngā nekehanga rerekē. Mā te tātari i ngā pihi muka maha i te wā kotahi, mēnā ka whakaatuhia e ngā pihi katoa ngā hikoinga i te wāhi kotahi, he raru honohono pea.

• Inehia, ka tātaihia te ngaronga hononga rua-ara i taua wāhi

• Tuhia ngā uara e hipa ana i ngā paerewa

• Whakatuwheratia te katinga hononga ka mahi i ngā mahi whakatikatika

Mena ko ētahi muka anake e whakaatu ana i te ngoikore i tētahi wāhi, ko ētahi kāore, ehara pea i te hononga te raruraru engari he hapa i roto i te tinana taura.

Ngā Tikanga Tauwāhi Hapa

• Ngā hapa tata-pito:Whakamahia te OTDR mai i te pūrua hei ine i te tawhiti mai i te pūwāhi honohono tata rawa atu.

• Ngā hapa o te pito tawhiti:Nā te iti o te tika i ngā tawhiti roa, whakamātauria mai i te katinga hononga tata.

• Whakakotahitia ngā raraunga OTDR me ngā tuhinga hanga me ngā mōhiohio mangere

• Whakahaerehia ngā inenga o te papa hei kimi i te hapa i roto i te awhe tata ki te 10 mita

Ka whakaitihia e tēnei huarahi te whānuitanga o te keri, ka whakaitihia ngā utu, ā, ka whakapotohia te wā whakatikatika.

Ngā Tikanga Whakatika

1. Ngā Hapa Pūwāhi-Whānui

• Whakatuwheratia te katinga honohono ka honohono anō i ngā muka

• Aroturukihia i te wā tūturu mā te whakamahi i te OTDR kia eke rā anō ki ngā taumata mate e whakaaetia ana

Ki te kore e angitu te honohono anō:

• Tirohia mēnā he rerekētanga o ngā ngongo ārai muka

• Kia tika te porowhita piko i te wā e takai ana i te muka

• Tirohia mēnā he pēhanga muka

Ki te mau tonu ngā raruraru, tirohia ngā wāhanga taura i mua atu, ā, i muri hoki i te hononga. Ki te whakapaetia he pakaru, tapahia, ka honoa anō ngā muka katoa.

2. Ngā Hapa o te Tinana Taura

Ko ngā take noa ko:

• Te piko, te takahuri rānei o te taura

• Ngā kino ā-pūkaha o waho (hei tauira, te pēhanga mai i ngā toka e puta ai te rerekētanga)

• Te rerekētanga o te ngongo pūwero e arahi ana ki te kōpeketanga muka

Otinga:

• Tapahia te wāhanga kua pakaru, ka honoa anō

• Mō ngā pakaru nui, tāutahia he katinga honohono, ā, whakatikahia ngā muka kua pāngia.

• Ki te mea e tika ana, tangohia te uhi o waho, ā, whakatikahia, whakakapia rānei ngā ngongo ārai kua pakaru.

Ngā Mahi Ārai

• Tirohia te roa o te taura tāpiri i mua i te honohono

• Tapahia he roa atu i ngā pito taura whakapae kia kore ai e pakaru

• Waiho kia nui te ngenge i ngā wāhi ngoikore e mōhiotia ana kia māmā ake ai te whakatikatika a meake nei

Ngā Whakaritenga Whakamātautau

Me mahi tahi ngā kaimahi whakamātautau me ngā tohunga hangarau o te mara, ā, me whakahaere ngā whakamātautau OTDR i ngā wāhanga e whai ake nei:

1. I muri i te otinga o te honohono

2. Kia oti te takai muka

3. I muri i te hiritanga o te hononga

I muri i te whakaū kua ea ngā take ngoikore, kātahi ka wehe atu te tīma i te papaanga.
