Kia mārama ki ngā roangaru o te 850nm, 1310nm me te 1550nm i roto i te muka whatu
Ka tautuhia te mārama e tōna roangaru, ā, i roto i ngā whakawhitiwhitinga muka whatu, ko te mārama e whakamahia ana kei roto i te rohe pūwhero, arā, he nui ake te roangaru o te mārama i tērā o te mārama e kitea ana. I roto i te whakawhitiwhitinga muka whatu, ko te roangaru noa ko te 800 ki te 1600nm, ā, ko ngā roangaru e whakamahia whānuitia ana ko te 850nm, 1310nm me te 1550nm.
Pūtake whakaahua:
Ina tīpakohia e te rama rere te roangaru tuku, ka whakaarohia te ngaronga muka me te marara. Ko te whāinga he tuku i te nuinga o ngā raraunga me te iti rawa o te ngaronga muka i te tawhiti roa. Ko te ngaronga o te kaha tohu i te wā tuku he whakaiti. E pā ana te whakaiti ki te roa o te ngaru, ko te roa o te ngaru, ko te iti ake o te whakaiti. He roa ake te roangaru o te mārama e whakamahia ana i roto i te muka i te 850, 1310, 1550nm, nō reira he iti ake te whakaiti o te muka, ā, ka iti ake hoki te ngaronga muka. Ā, tata kore rawa he mimiti o ēnei roangaru e toru, he mea tino pai mō te tuku i roto i ngā muka whatu hei puna mārama e wātea ana.
Pūtake whakaahua:
I roto i te whakawhitiwhiti muka whatu, ka taea te wehewehe i te muka whatu ki te aratau kotahi me te aratau maha. Ko te rohe roangaru 850nm he tikanga whakawhitiwhiti muka whatu aratau maha, ko te 1550nm he aratau kotahi, ā, e rua ngā momo o te 1310nm, arā, te aratau kotahi me te aratau maha. E ai ki te ITU-T, ko te whakaiti o te 1310nm e taunakitia ana kia ≤0.4dB/km, ā, ko te whakaiti o te 1550nm he ≤0.3dB/km. Ā, ko te ngaronga i te 850nm he 2.5dB/km. Ko te ngaronga muka ka heke i te nuinga o te wā i te pikinga o te roangaru. Ko te roangaru pokapū o te 1550 nm huri noa i te roopu-C (1525-1565nm) e kiia ana ko te matapihi ngaronga kore, ko te tikanga ko te whakaiti o te muka quartz te mea iti rawa i tēnei roangaru.
Kei roto i te "Silicon Valley" o Haina a Beijing Rofea Optoelectronics Co., Ltd. – Beijing Zhongguancun, he umanga hangarau teitei e whakatapua ana ki te mahi ki ngā whare rangahau o roto me tāwāhi, ngā whare rangahau, ngā whare wānanga me ngā kaimahi rangahau pūtaiao hinonga. Ko te nuinga o tā mātou kamupene he rangahau me te whakawhanake motuhake, te hoahoa, te hanga, te hoko hua optoelectronic, ā, e whakarato ana i ngā otinga auaha me ngā ratonga ngaio, whaiaro mō ngā kairangahau pūtaiao me ngā miihini ahumahi. Whai muri i ngā tau o te auahatanga motuhake, kua hangaia he raupapa hua photoelectric whai rawa me te tino pai, e whakamahia whānuitia ana i roto i ngā umanga ā-rohe, hōia, kawe waka, hiko, pūtea, mātauranga, hauora me ētahi atu ahumahi.
