Abaphuhlisi beesekhanekhrikhi zekhompyutheni babefanele bazisombulule imisebenzi ehlukahlukeneyo. Kancinci, kwakukho izisombululo ezikhokelela ekudalweni kwamacandelo ahlukeneyo asetyenziswa kwizicwangciso ezahlukeneyo. Umzekelo omhle ngababizwa ngokuba yi-multiplexers kunye ne-demultiplexers. Ngokufika kobuchwepheshe obutsha kunye namaqhinga, ziba zihambelana ngakumbi kwaye zithembekile. Into yodwa engatshintshiyo yimiqathango leyo zonke ezi zixhobo zisebenza ngayo.
Xa usebenzisa ii-circuits ze-elektroniki, kufuneka ukuba utshintshe inombolo ethile yempawu. Omnye wabo ubonakala kwimveliso yecebo, ngelixa ezinye zivaliwe okwesikhashana. Konke oku kwenzeka ngokusukela ekufundeni kwibhasi yokulawula yekhowudi ye-digital. Iqulethe ulwazi malunga neyiphi imveliso ekufuneka ishintshwe. Kwakhona kunomdla ukuguqula utshintsho. Kule meko, isalathisi esisuka kwelinye galelo livela kwenye yeziphumo ezininzi zecebo. Ulawulo kule meko lwenzeka kwakhona ngesiseko segama ledijithali. Abaxhamli be-multipleplexers kunye ne-demultiplexers baphatha kakuhle lo msebenzi. Zizixhobo ezihambelanayo zanamhlanje zineempawu ezifanelekileyo zokusebenza.
Ezi zixhobo zisetyenziswa ngokubanzi kwi-othomathikhi yombaneli, ukukhulumisana kwe-fiber optic, ekwakhiweni kweesekethe zombane. Abaxhamli be-demplexers kunye ne-demultiplexers bathathe inxaxheba ekuguquleni kwamasayinal aphezulu. Izicwangciso zesiphaluka ezahlukeneyo ezisekelwe kwezi zixhobo zivumela ukuba uqaphele ingcamango. Umzekelo, unako ukuguqula ikhowudi efanayo kunye nekhowudi ye-serial; Shintsha utshintsho lweedatha; Bhalisa ulwazi usebenzisa i-algorithm eyenziwe ngaphambili kunye nokunye okuninzi. I-Multiplexers kunye ne-demultiplexers zidibaniswa kalula kwisiphaluka, ukuze zifumane i-I / O ngaphezulu. Ngamanye amaxesha oku kuyimfuneko ukuguqula inani elikhulu leziteshi. Ukusebenzisa into yokuba i-multiplexer iyisistim esisebenzisa umsebenzi we-demultiplexer inverse, kunokwenzeka ukuyila iisekethe ngokusebenzisa zombini izixhobo.
Umzekelo omhle wokusetyenziswa kwezi fowuni kwi-fiber-optic yokunxibelelana inokusebenza njenge-multiplexer ye-DWDM. Ifowuni ifumana iimpawu kwiziphumo ezine. Emva kokuguqulwa okufanelekileyo, ungayifumana isitya esifunekayo kwenye yee- COM port. Isixhobo sinceda ukudibanisa izixhobo ezahlukeneyo kwaye siklanywe ngokukodwa ukusebenzisana ne-EDFA kunye ne-BLUE / Red-splitter amplifiers. Iyakwazi ukuguqula izibonakaliso zenkxaso ngefayile ehambayo ukusuka kwi-10 MHz ukuya ku-10 GHz. Oku kukwanele ukugubungela uluhlu lokusebenza kwezixhobo ezininzi kwaye kuqinisekiswe ukuguqulwa kwamanqaku athembekileyo. Umlinganiselo ophantsi wokulinda kwi-device operation (<2.5 DBL) uncedisa umfanekiso omeleyo. I-Compact, encinci kwaye efanelekileyo ekusebenziseni ifowuni ithandwa kakhulu phakathi kwabaqulunqi.
Ngokuphuhliswa kwethekhnoloji yokuvelisa i-multi-demultiplexers, kukho ukuthambekela ngokukhawuleza ukunciphisa ubungakanani, ukwandisa isantya ngokuguqulwa kwamagqabantshintshi, ukunciphisa izinga lokumanyaniswa nokunyusa ukuthembeka ekusebenzeni kwazo.
