Ngā o iahiko hiko whai ki te whakaoti te whānuitanga o ngā mahi. Āta i reira nga whakatau i arahina ki te hanga o ngā waeine motuhake, e kua whakamahia i roto i ngā kaupapa. Ko te tauira pai, ko te pera-ka karanga multiplexers me demultiplexers. Ki te haerenga mai o hangarau me ngā wāhanga hou e hoko piki kiato, me te pono i roto i te mahi. e kore e huri i tetahi anake te mea - te parau tumu rawa i runga i nei te mahi me katoa o enei whakaaro.
A, no te Ko maha e tika ana te ara iahiko hiko ki te whakawhiti i te maha o tohu. Ko tētahi o ratou puta i runga i te pūrere putanga, me te toenga e rangitahi āraia. tenei katoa e wahi i runga i te pūtake o te pānui i te waehere mana o te pahi mana mamati. Oku i ai e ngā mōhiohio e pā ana ki nei o te kōkuhunga me whakawhiti. Ko reira ano hoki ngā, me te tahatua. I roto i tenei take, puta he tohu tāuru kotahi i runga i tetahi o te maha pūrere putanga. Mana i roto i tenei take puta ano hoki i runga i te pūtake o te kupu mamati. Ki tenei mahi maitai fekuki multiplexers me demultiplexers. Tenei taputapu hou kiato ki pai ana te whakahaere.
E whānui ana ēnei whakaaro whakamahia i roto i te hikohiko, kōrero whatu, i roto i te hanga o iahiko hiko. E whai wāhi Multiplexers me demultiplexers i te huringa o tohu tiketike-auau. hoahoa ara iahiko Various i runga i enei whakaaro kia taea ki te ite i te whakaaro tino maia. Hei tauira, ka taea e koe te tahuri i te waehere whakarara i roto i rangatū me te hurihia; te huri i te kawa whakawhiti raraunga; mōhiohio whakamuna te whakamahi i hātepe i mua-whakawhanakehia me te ake. Multiplexers me demultiplexers ngāwari te whakauru i roto i te ara iahiko, i roto i te tikanga ki te whiwhi i te maha nui o ngā kōkuhunga / whakaputanga. I te tahi taime te mea e tika ana ki te tahuri i te maha nui o awa. Mā te whakamahi i te meka te multiplexer e - he pūrere e whakatinana te mahi kōaro o te demultiplexer iahiko e taea te hangaia ki te pūrere e rua.
He tauira pai o te whakamahi o enei whakaaro i roto i te hono muka whatu kia mahi rite te multiplexer DWDM. Ka whiwhi te taputapu tohu i runga i wha kōkuhunga. I muri i te hurihanga e tika ana ka taea e ia farii i te teihana e hiahiatia ana ki te tetahi o te whakaari COM-tauranga. he pai hoki ōrite te momo o ngā pūrere te pūrere me te hangaia āta ki te mahi ki a EDFA amplifiers me KIKORANGI / Whero-Kairitu. He mea e taea ki te tahuri i te tohu tāuru ki te auautanga kawe o 10 MHz ki 10 GH. He rawaka ki karapoti te whānuitanga o maha whakaaro, me te whakarato i te faafariuraa tohu pono tenei. kīnaki tauwehe attenuation iti te pikitia pai whānui i roto i te mahi (<2.5 DBl). He rongonui i roto i kaihoahoa kiato, wāhi-ora, me te ngāwari-ki-te whakamahi pūrere.
Ki te whanaketanga o te hangarau ahumahi o maha - me demultiplexers kua kua he au whakararo on i roto i te āhuatanga whānui, ake i te tere ka whakaiti tahuri tohu attenuation me te whakanui ake te tika i roto i to ratou mahi.
