Whakaahuatanga me ngā Āhuatanga
Kua rongonui ngā whatunga FTTH (muka-ki-te-kāinga) mō ngā hononga Ipurangi pono me te mahi teitei mō ngā kāinga me ngā pakihi iti. Kua hangaia te WDM Fiber Optical Receiver mō tēnei, me ngā hononga whatu WDM (Wavelength Division Multiplexing) me SC/APC kua hangaia ki roto, kia taea ai te hototahi ki te whānuitanga o ngā taputapu me ngā whatunga. He pai te mahi whakamarara wera a te anga kōtaha konumohe whakarewa, ā, he ngāwari te kawe me te tāuta i te hoahoa iti me te ātaahua.
He whānui te mana whatu o tēnei Kaiwhiwhi Whatu muka SSR4040W WDM (-20dBm ki te +2dBm), ā, he pai mō ngā hiahia whatunga ngāwari. He pai te rārangi me te papatahi o te pūnaha, ko te tikanga he hononga ipurangi tere me te pumau. Ko tōna whānuitanga auau o te 45-2400MHz he mea tino pai mō ngā kaiwhakamahi mutunga CATV me Sat-IF, he mea tāpiri uara hei otinga kotahi-mutu. Ko tētahi atu painga o te whatunga FTTH ko te pai o te tiaki ārai RF (auau reo irirangi), e āwhina ana ki te whakaiti i te pokanoa me te whakarite kia pai ake te mahi a ō taputapu. Ko te momo putanga RF o te +79dBuV mō ia hongere i te 3.5% OMI (22dBmV whakaurunga whakarerekētanga) ka whakarite hoki kia whiwhi koe i te kaha tohu pai rawa atu mō tō hononga ipurangi.
Heoi anō, kei te kaiwhiwhi whatu te Tohu Mana Whatu Kakariki-LED (Mana whatu >-18dBm) me te Tohu Mana Whatu Whero-LED (Mana whatu <-18dBm) e tohu ana i te kaha o te tohu, me te whakarite kia mōhio te kaiwhakamahi mēnā he pai, he ngoikore rānei te kaha o te tohu.
He pai mō te whakamahi i te kāinga, i te tari iti rānei, nā te hoahoa kiato o te whatunga FTTH ka māmā ake te tāutanga me te whakahaere. Kei te kaiwhiwhi whatu hoki he urutau hiko me te taura hiko e ōrite ana hei hono ngāwari ki tō tatūnga whatunga o nāianei. Hei whakamutunga, ki te rapu koe i tētahi otinga pono me te mahi teitei mō ō hiahia hononga Ipurangi, whakaarohia ngā whatunga FTTH. Mā tōna WDM kua hangaia ki roto, te mana whatu whānui, te raina pai, te papatahi, te awhe auau, me te hoahoa kiato me te mama, ka whakaratohia e tēnei kaiwhiwhi whatu he otinga kotahi-mutunga mō ō otinga kāinga, mō ngā hiahia whatunga tari iti rānei. Whakapā mai ki a mātou i tēnei rā ki te ako atu mō te āhua o te whatunga FTTH e taea ai te whakatutuki i ō hiahia me te whakarite hononga pono mō ngā tau e haere ake nei!
