Whakakaha whatu haurua-haurua whakarei ake

Whakarei akewhakakaha whatu haurua-haurua

Ko te whakakaha whatu haurua-haurua whakarei ake he putanga whakapai ake o te whakakaha whatu haurua-haurua (Whakakaha whatu SOA). He whakakaha e whakamahi ana i ngā haurua-ira hei whakarato i te reo whakanui. He rite tōna hanganga ki te diode taiaho Fabry-Pero, engari ko te nuinga o te wā ka pania te mata pito ki te kiriata ārai-whakaata. Kei roto i te hoahoa hou ngā kiriata ārai-whakaata me ngā arataki ngaru me ngā rohe matapihi, ka taea te whakaiti i te whakaata o te mata pito ki raro iho i te 0.001%. He tino whai hua ngā whakakaha whatu whakarei ake mahi-teitei ina whakakaha ana i ngā tohu (whatu), nā te mea he tūponotanga nui o te ngaronga tohu i te wā e tukuna ana i tawhiti. Mai i te mea ka whakakaha tika te tohu whatu, ko te huarahi tuku iho o te huri hei tohu hiko i mua ka kore e whai hua. Nō reira, ko te whakamahinga oSOAKa tino whakapai ake i te pai o te tuku. Ko tēnei hangarau e whakamahia ana mō te wehewehe mana me te utu mō te ngaronga i roto i ngā whatunga WDM.

Ngā horopaki tono

I roto i ngā pūnaha whakawhitiwhiti muka whatu, ka taea te whakamahi i ngā whakakaha whatu haurua-haurua (SOA) i roto i ngā wāhanga tono maha hei whakarei ake i te mahi me te tawhiti tuku o te pūnaha whakawhitiwhiti. Ko ngā tono e whai ake nei ko ētahi o ngā tono noa o te whakamahi i te whakakaha SOA i roto i ngā pūnaha whakawhitiwhiti muka whatu:

Whakakaha-mua: SOAwhakakaha whatuKa taea te whakamahi hei whakakaha i te pito whiwhi whatu i roto i ngā pūnaha whakawhitiwhiti tawhiti me ngā muka whatu neke atu i te 100 kiromita, hei whakarei ake, hei whakanui ake rānei i te kaha o te putanga tohu i roto i ngā pūnaha whakawhitiwhiti muka whatu tawhiti, hei utu mō te tawhiti tuku kore rawa i puta mai i te putanga ngoikore o ngā tohu iti. Hei tāpiri, ka taea hoki te whakamahi i te SOA hei whakatinana i te hangarau whakaora tohu whatunga whatu i roto i ngā pūnaha whakawhitiwhiti muka whatu.

Te whakahoutanga o te tohu whatu katoa: I roto i ngā whatunga whatu, i te pikinga ake o te tawhiti tuku, ka heke te kaha o ngā tohu whatu nā te ngoikore, te marara, te haruru, te wiri o te wā me te whakawhitiwhiti kōrero, me ētahi atu. Nō reira, i roto i te tuku tawhiti, me utu ngā tohu whatu kua heke kia tika ai ngā mōhiohio kua tukuna. Ko te whakahoutanga o te tohu whatu katoa e pā ana ki te whakanui anō, te hanga anō me te wā anō. Ka taea te whakatutuki i te whakanui anō mā roto i ngā whakanui whatu pēnei i ngā whakanui whatu semiconductor, EDFA me ngā whakanui Raman (RFA).

I roto i ngā pūnaha pūoko muka whatu, ngā whakakaha whatu haurua-haurua (Whakakaha SOA) ka taea te whakamahi hei whakanui i ngā tohu whatu, ā, mā reira ka whakarei ake i te aro me te tika o ngā pūoko. Ko ngā mea e whai ake nei ko ētahi o ngā whakamahinga noa o te whakamahi i te SOA i roto i ngā pūnaha pūoko muka whatu:

Te ine i te taumahatanga muka whatu: Whakapirihia te muka whatu ki te mea e tika ana kia inehia te taumahatanga. Ina pāngia te mea e te taumahatanga, ka paku rerekē te roa o te muka whatu i te panonitanga o te taumahatanga, ā, ka whakarerekētia te roangaru, te wā rānei o te tohu whatu ki te pūoko PD. Ka taea e te whakakaha SOA te whakatutuki i te mahi teitei ake o te pūoko mā te whakanui me te tukatuka i te tohu whatu.

Te ine i te pēhanga muka whatu: Mā te whakakotahi i ngā muka whatu me ngā rauemi tairongo-pēhanga, ka puta he panoni ki te ngaronga whatu i roto i te muka whatu ina pēhia tetahi mea. Ka taea te whakamahi i te SOA hei whakanui i tēnei tohu whatu ngoikore hei whakatutuki i te ine pēhanga tairongo.

He taputapu matua te whakakaha whatu haurua-haurua SOA i roto i ngā mara o te whakawhitiwhiti muka whatu me te pūoko muka whatu. Mā te whakanui me te tukatuka i ngā tohu whatu, ka whakarei ake i te mahi a te pūnaha me te aro o te pūoko. He mea nui ēnei tono mō te whakatutuki i te whakawhitiwhiti muka whatu tere, pumau me te pono, me te pūoko muka whatu tika me te whai hua.
