Apo iyokutapurirana simbayemugero wemuviri wakakwira kupfuura kudiwa kwechiratidzo chimwe, chiteshi chinogona kugovaniswa nemasaini akawanda.Semuyenzaniso, hunde yenharembozha inowanzova nezviuru zvezviratidzo zvinopfuudzwa pane imwe optical fiber.Multiplexing ndiyo tekinoroji inogadzirisa mashandisiro echiteshi kufambisa masaini akawanda panguva imwe chete.Chinangwa ndechekushandisa zvizere frequency bhendi kana nguva zviwanikwa zvechiteshi uye kuvandudza mwero wekushandiswa kwechiteshi.
Panenzira mbiri dzakajairika dzechiratidzo chekuwedzera: frequency division multiplexing (FDM) uye nguva division multiplexing (TDM) Nguva yekuparadzanisa multiplexing inowanzo shandiswa pakuwanda kwemasaini edhijitari.Frequency division multiplexing inonyanya kushandiswa kuwedzeredza masaini eanalogue asi inogona kushandiswawo kumasaini edhijitari.Ichi chikamu chichakurukura musimboti uye kushandiswa kweFDM.
Frequency division Multiplexinginzira yekuwandisa inopatsanura machanera zvichienderana nekuwanda.MuFDM, bandwidth yechiteshi yakakamurwa kuita kuwanda kwema frequency mabhendi (madiki-channel) asingapindirane.Imwe neimwe nzira yemasaini inotora imwe yediki-channel, uye isina kushandiswa frequency mabhendi (mabhendi evarindi) anofanirwa kuchengetwa pakati pematanho kudzivirira kupindirana kwechiratidzo.Pakupera kwekugamuchira, bhendi-pass sefa yakakodzera inoparadzanisa masaini akawanda uye inodzoreredza masaini anodiwa.
Mufananidzo unotevera unoratidzaiyo musimboti block dhizaini yeiyo frequency division multiplexing system.Pakupera kwekutumira, imwe neimwe baseband izwi siginecha inotanga kupfuura nepasi-pass sefa (LPF) kudzikamisa iyo yepamusoro frequency yechiratidzo chega chega.Zvadaro, chiteshi chega chega chezviratidzo chinogadziridzwa kune akasiyana anotakura ma frequency, kuitira kuti imwe neimwe nzira yezviratidzo inotamiswa kune yayo frequency renji, yobva yasanganiswa uye kutumirwa kuchiteshi chekufambisa.Mutsara webhendi-pass mafirita ane akasiyana epakati frequency pamagumo ekugamuchira anoshandiswa kupatsanura masaini akagadziridzwa.Mushure mekunge vaderedzwa, iwo anowirirana baseband masaini ega ega chiteshi anodzoserwa.
Kuitira kudzivirirakupindiranapakati pezviratidzo zviri pedyo, mutakuri wefrequency F anofanirwa kusarudzwa zvine musoro_ c1,f_ c2,···,f_ Cn kuitira kuti rimwe bhendi rinorinda richengetedzwe pakati pemasaini akagadziridzwa.
