E whakamahia ana ngā Kāri OTDR mō te Pouaka DCI
OTDR whakaata rohe wā whatu, ka taea te ine i te roa muka, te whakaiti i te tuku muka whatu, te whakaiti i te hononga me te taunga hapa, me ētahi atu. Ka taea te whakamahi ki te aroturuki i te taura muka whatu, te hanga me te tiaki i te taura muka whatu.
I te wā whakamātautau OTDR, ka panaia te LD e te pā o te pūhiko e te pūhiko hei whakaputa i ngā pā mārama, ka werohia ki roto i te muka whatu hei whakamātautau mā te hononga aronga. Nā te mea he poke kei roto i te muka, ka puta he mirumiru me ētahi atu marara, ka marara whakamuri ētahi e mōhiotia ana ko te mārama marara whakamuri (BACK SCATTERINGLIGHT), me te mārama whakaata FRESENL e whakaputaina ana e te mata pito muka kore taurite, me te whakaata hoki ki te hononga, ki roto i te photodiode, ki roto i te pā hiko. He tino ngoikore tēnei mārama whakaata, nō reira ka tukuna, ka kohia, ka whakatikatikahia, ka whakanuia, ka toharitehia, ka tukatukahia, kātahi ka tukuna ngā raraunga ki te tūāpapa whakahaere whatunga. He āhuatanga tōna he whānuitanga hihiri teitei me te taumata whakataunga teitei.
Pepa raraunga OTDR Mahi Tautoko mō te tawhiti hononga muka, te whakaitiiti, te ngaronga katoa me ētahi atu tawhā o te whakamātautau Mokowātau 1mokowā Ngā tauranga E whakarato ana i ngā atanga whakamātautau e 8 (kua tīpakohia e te pana whatu), ka taea te hono atu ki te whakamātautau hononga muka whatu 8-matua Ngaru roanga mahi 1625 nm Awhe hihiri ≥30 dB Awhe whānui o te pātere 0.02 ~ 20 tāra Te whānuitanga kitea mōrahi ≥80 kiromita Te tika o te whakamātautau ngaronga ±0.5 dB Te tika o te ine i te whānuitanga <20 mita Matapo takahanga <10 mita Rohe mate whakaitiiti <20 mita
Taupānga: He mea pai mō te tātaritanga tere me te whakahaere pokapū i ngā hapa muka whatu. Whakamahia mō te Pouaka DCI.
