Oyambitsa magetsi apakompyuta amayenera kuthetsa ntchito zosiyanasiyana. Pang'onopang'ono, panali njira zomwe zinachititsa kuti pakhale magulu osiyanasiyana omwe amagwiritsidwa ntchito pazinthu zosiyanasiyana. Chitsanzo chabwino ndi otchedwa multiplexers ndi demultiplexers. Pakubwera kwa matekinoloje atsopano ndi zinthu, iwo akukhala ofanana kwambiri ndi odalirika akugwira ntchito. Chinthu chokha chimene sichimasintha ndicho mfundo yomwe zipangizo zonsezi zimagwirira ntchito.
Mukamagwiritsa ntchito maulendo apakompyuta, nthawi zambiri zimakhala zofunikira kuti musinthe chizindikiro china. Mmodzi mwa iwo amawoneka pa zotsatira za chipangizo, pamene zinazoletsedwa kwa kanthawi. Zonsezi zimachitika pamaziko a kuwerenga kuchokera ku basi yoyendetsa mphamvu ya digito. Lili ndi chidziwitso chokhudza malemba omwe ayenera kusinthidwa. N'zosangalatsanso kuti musinthe kusintha. Pachifukwa ichi, chizindikiro kuchokera kumalo amodzi chikuwonekera pa chimodzi mwa zochitika zingapo za chipangizochi. Utsogoleri pa nkhaniyi umapezanso pamawu adijito. Ambiri ndi amodzi omwe amadzimangirira bwino amadana nawo ntchitoyi. Iwo ndi makompyuta amakono omwe ali ndi makhalidwe abwino.
Zipangizozi zimagwiritsidwa ntchito kwambiri pa wailesi yakanema, fiber optic communication, pomanga maulendo apakompyuta. Ambiri ndi anthu ogwira ntchito m'mayiko ena amathandizira kutembenuka kwa zizindikiro zapamwamba. Njira zothetsera maulendo osiyanasiyana zomwe zimagwiritsidwa ntchito pa zipangizozi zimakulolani kuti muzindikire malingaliro olimba mtima. Mwachitsanzo, mutha kusintha code yofanana ndi code yapadera ndi mosiyana; Sinthani protocol yodutsa deta; Lembani chidziwitso pogwiritsira ntchito ndondomeko yoyamba yokonzedweratu ndi zina zambiri. Ambiri ndi amodzi omwe amadzimangirira anthu amodzi amayendayenda mosavuta, kuti apeze zambiri za I / O. Nthawi zina izi ndizofunika kusintha njira zambiri. Pogwiritsa ntchito mfundo yakuti multiplexer ndi chipangizo chomwe chimagwiritsira ntchito ntchito yowonongeka kwa demultiplexer, n'zotheka kupanga mapurogalamu pogwiritsa ntchito zipangizo zonsezo.
Chitsanzo chabwino cha kugwiritsa ntchito zipangizozi mu kuyankhulana kwa magetsi kumatha kukhala ngati multiplexer DWDM. Chipangizocho chimalandira zizindikiro pazinayi zina. Pambuyo pa kutembenuka komweko, mukhoza kupeza njira yomwe mukufuna ku imodzi mwa ma doko a COM. Chojambuliracho n'chothandiza kugwirizanitsa zipangizo zosiyanasiyana ndipo chimapangidwa kuti zigwiritse ntchito ndi EDFA ndi BLUE / Red-splitter amplifiers. Zimatha kutembenuza zizindikiro zogwiritsira ntchito pafupipafupi 10 MHz mpaka 10 GHz. Izi ndi zokwanira kutseka momwe zipangizo zambiri zimagwirira ntchito ndikuonetsetsa kuti zizindikiro zosinthika zowoneka. Kuchepa kwa chiwerengero cha kuchepa kwa opaleshoni (<2.5 DBL) kumaphatikizapo chithunzi chabwino. Chogwirana, chochepa ndi chophweka kugwiritsa ntchito chipangizochi ndi chotchuka kwambiri pakati pa okonza mapulani.
Ndi chitukuko cha zipangizo zamakono zopanga ma multi-demoltiplexers, pali chizoloŵezi chokhalira kuchepetsa kukula, kuonjezera liwiro la kutembenuka kwa chizindikiro, kuchepetsa kuchuluka kwa kuchepa ndi kuonjezera kudalirika mu ntchito yawo.
