Ke ʻoi aku ka kiʻekiʻe o ka hoʻouna ʻana o kahi ala kino ma mua o ke koi ʻana i hoʻokahi hōʻailona, hiki ke kaʻana like ʻia ke kahawai e nā hōʻailona he nui, no ka laʻana, ʻo ka laina kumu o kahi ʻōnaehana kelepona he mau kaukani mau hōʻailona i hoʻouna ʻia i hoʻokahi fiber. ʻO ka Multiplexing kahi ʻenehana e hoʻoponopono ai pehea e hoʻohana ai i kahi ala e hoʻouna i nā hōʻailona lehulehu i ka manawa like. ʻO kāna kumu, ʻo ia ka hoʻohana piha ʻana i ke alapine alapine a i ʻole nā kumuwaiwai manawa o ke kahawai a hoʻomaikaʻi i ka helu hoʻohana ʻana o ke kahawai. ʻElua mau ala maʻamau o ka hōʻailona multiplexing: Frequency division multiplexing (FDM) a me Time division multiplexing (TDM). Hoʻohana maʻamau ka hoʻohui ʻana i nā hōʻailona kikohoʻe a e kūkākūkā ʻia ma ka Mokuna 10. Hoʻohana nui ʻia ka hoʻohui ʻana o nā hōʻailona analog, akā hiki ke hoʻohana ʻia no nā hōʻailona kikohoʻe. E kūkākūkā kēia ʻāpana i nā loina a me nā noi o FDM.
ʻO ka hoʻokaʻawale pinepine ʻana he ʻano multiplexing e hoʻokaʻawale i nā alapine e like me ke alapine. Ma FDM, ua māhele ʻia ka bandwidth o ke kahawai i mau ʻāpana alapine (subchannels) ʻaʻole i hoʻopili ʻia, a aia kēlā me kēia hōʻailona i kekahi o nā subchannels, a pono e loaʻa nā alapine i hoʻohana ʻole ʻia (nā pale pale) ma waena o nā ala e pale ai i ka overlap. Ma ka hopena e loaʻa ai, hoʻohana ʻia ka kānana bandpass kūpono e hoʻokaʻawale i nā hōʻailona lehulehu, i mea e hoʻihoʻi ai i nā hōʻailona i koi ʻia.
Hōʻike ke kiʻikuhi ma lalo nei i ke kiʻikuhi poloka o ka ʻōnaehana hoʻonui pinepine. Ma ka hopena o ka hoʻouna ʻana, e kau mua ʻia kēlā me kēia hōʻailona leo baseband ma kahi kānana low-pass (LPF) i mea e kaupalena ʻia ai ke alapine kiʻekiʻe o kēlā me kēia hōʻailona. A laila, hoʻololi ʻia kēlā me kēia hōʻailona i kahi alapine ʻokoʻa, no laila e neʻe ʻia kēlā me kēia hōʻailona i kona ʻano iho, a laila synthesized i loko o ke kahawai no ka hoʻouna ʻana. Ma ka hopena o ka loaʻa ʻana, hoʻohana ʻia kahi pūʻulu o nā kānana band-pass me nā alapine waena like ʻole e hoʻokaʻawale i nā hōʻailona modulated, a e hoʻihoʻi ʻia nā hōʻailona baseband pili ma hope o ka demodulate.
I mea e pale ai i ka hoʻopaʻapaʻa like ʻana ma waena o nā hōʻailona pili, pono e koho pono ʻia nā alapine lawe f_c1,f_c2, f_cn e waiho i kekahi pūʻulu pale ma waena o kēlā me kēia kikoʻī hōʻailona modulated.
ʻO ka mea i luna ʻo Shenzhen HDV Phoelectron Technology Ltd. e lawe iā ʻoe e pili ana i ka wehewehe ʻike "frequency division multiplexing", manaʻolana e kōkua iā ʻoe, a me Shenzhen HDV Phoelectron Technology Ltd.ONUmoʻo, moʻo transceiver,OLTmoʻo, akā hana pū kekahi moʻo module, e like me: Communication optical module, optical communication module, network optical module, communication optical module, optical fiber module, Ethernet optical fiber module, etc., hiki ke hāʻawi i ka lawelawe kūpono kūpono no nā mea hoʻohana like ʻole. , hoʻokipa i kou kipa ʻana.
