He taputapu whakawhiti tohu whatu ano hoki nga taputapu whakawhiti. He hangarau pakeke nga kaiwhakawhiti whatu o tawahi engari he utu nui. Ahakoa karekau i tino pakeke nga kaiwhakawhiti whatu o roto i te hangarau, kaore i te utu nui ki te mahi ki nga mea o roto. Na, he aha te kowhiringa o nga kaiwhakawhiti whatu?

Whakatupatotanga mo te hoko i nga whakawhiti whatu whatu: Mai i te tohu ka tukuna ki te muka whatu, ka taea te wehea nga transceivers optical ki nga transceivers optical analog based on the analog technology and digital optical transceivers based on digital technology. Ko te maataapono mahi o te whakawhiti whatu tairitenga he mea ke atu i te whakarereketanga me te whakahekeheke, te tātari me te whakaranu tohu, me era atu. Ahakoa he LED, he LD ranei, ko ona ahuatanga whakarereketanga whakaahua ehara i te raina. I roto i te tukanga tuku tohu, he rerekee, he pokanoa me etahi atu raruraru e kore e taea te karo i roto i te tukatuka tairitenga e kore e taea te karo, me nga hangarau e kore e taea te whakakore i roto i te whakawhitinga kaha nui me te whakawhitinga whakauru maha. uaua.

He rereke te ahuatanga o nga kaiwhakawhiti whatu mamati. E rua noa nga ahua o te "muka me te "kaore he muka" i roto i te muka whatu. Na reira, ko te raina o te puna marama kaore i te teitei, kaore ranei he whakaritenga, na reira ka karo i te mate tohu i roto i te tukanga tukatuka. I tua atu, he ngawari noa te kawe i nga whakawhiti whakaata mamati ki te whakatutuki i nga hongere-maha me te whakawhiti whakauru o nga tohu maha. Mai i te mea ka huri noa ki nga tohu mamati, ka taea te ngawari te whakawhiti i nga waahana maha me nga tohu maha me te awhina o te hangarau TDM (Time Division Multiplexing). Ka taea e nga kaihanga whakawhiti whatu o naianei te tuku 10 nga whakaahua ataata-a-waa-a-tui kaore ano kia kopaki i runga i te hongere roangaru i te wa kotahi.

Topology whatu whatu whatu, whatu whatu whatu topology network whakatau te momo o te ataata whatu transceiver. E ai ki te topology o te whatunga whakawhiti muka whatu, i tua atu ki te tuku ira-ki-ira tuku whatu transceivers, i reira he momo node-momo me te mowhiti whatunga whatu transceivers ki te whiriwhiri i. Ka whakakotahihia e te kaiwhakawhiti whakaata ataata momo node nga pona o mua ki te whatunga mekameka, ki te whatunga rakau ranei. Ka whiwhi tuatahi te miihini node i te tohu ki ia node, ka huri hei tohu hiko, ka whakawhiti me te maha o te tohu ki te node o te rohe. I muri i te huringa photoelectric, ka whakamahia te hangarau WDM mo te maha. Whakamahia he muka whatu mo te tuku. Karekau he huringa tairitenga-ki-mamati e mahia ana ki ia pona, e whakaiti ana i te whakahekenga tohu.

He tere te tere o te whakawhiti o te whakawhiti whatu, he maamaa te mata, ka taea te whakamahi i nga momo o waho. He tino whanui te mahi me te whakamahia whanui i roto i te umanga.

Shenzhen JHA Technology Co., Ltd, He 13 Tau te Kaiwhakarato o te Ao mo te Whakawhitiwhiti Raraunga Raraunga Ahumahi, Mahinga Pono me te Tautoko Ake.
