Onjiniyela of kagesi kufanele ukuxazulula ezihlukahlukene imisebenzi. Kancane kancane kwakukhona izinqumo ezaholela ukudalwa amayunithi elehlukile, asetshenziswa amaqhinga ahlukahlukene. Isibonelo esihle okubizwa ngokuthi multiplexers futhi demultiplexers. Njengoba sekunama-ubuchwepheshe obusha futhi izingxenye ziba compact nokunokwethenjelwa ukusebenza. Ayishintshi into eyodwa kuphela - kakhulu isimiso lapho umsebenzi futhi zonke lezi amadivaysi.
Lapho isifunda electronic Ngokuvamile kuye kudingeke ukushintshela eziningi amasignali. Omunye wabo kuvela idivayisi okukhipha, kanti bonke abanye avimbelwe okwesikhashana. Konke lokhu kuthatha indawo ngesisekelo the wokufundwayo kusukela ikhodi ukulawula digital ukulawula ibhasi. Liqukethe ulwazi mayelana nokuthi iziphi we okokufaka kumelwe luvulwe. Kuyathakazelisa, kube yibo. Kulokhu, isiginali okokufaka olulodwa livela kwenye kumadivaysi amaningana okukhiphayo. Control kuleli cala futhi kwenzeka ngesisekelo izwi digital. Nge lo msebenzi babhekane kahle multiplexers futhi demultiplexers. Lokhu zikagesi compact esine ukusebenza okuhle.
Lezi amadivayisi kabanzi electronics, ukuxhumana optical, ekwakhiweni kagesi. Multiplexers futhi demultiplexers zinengxenye ekuguquleni amasignali ephezulu imvamisa. wesifunda imiklamo ehlukahlukene esekelwe lezi amadivaysi enze kube nokwenzeka ukuba uqaphele imibono kwakwakhiwa kakhulu. Ngokwesibonelo, ungakwazi ukuguqula ikhodi ukufana serial okuphambene nalokho; ukushintsha olandelwayo ukudluliswa kwedatha; Imininingwane wemfihlo usebenzisa algorithm pre-ithuthukiswe nokuningi. Multiplexers futhi demultiplexers kalula adidiyele yesifunda, ukuze bathole inombolo enkulu okokufaka / okukhiphayo. Ngesinye isikhathi kuyadingeka ukuba ukuguqula inombolo enkulu iziteshi. Ukusebenzisa iqiniso lokuthi Multiplexer - idivayisi nokobana umsebenzi ephambene demultiplexer wesifunda kungenziwa yakhelwe kokubili amadivaysi.
Isibonelo esihle ukusetshenziswa kwalezi amadivaysi e-optical fibre isixhumanisi angase bayisibonelo Multiplexer DWDM. I-apharathasi uthola signals okokufaka ezine. Ngemva ukuguqulwa efanelekayo bangathola isiteshi wayefisa omunye serial COM-nezimbobo. Idivayisi kuyasiza zokufanisa ezihlukahlukene kumadivayisi futhi eziklanyelwe ukusebenza EDFA yokukhulisa umsindo ELILUHLAZA / Red-idabula. It uyakwazi ukuguqula amasignali okokufaka nge imvamisa othwala 10 MHz ukuze 10 GHz. Lokhu kwanele ukuze ahlanganise uhla kumadivayisi amaningi futhi unikeze okunokwethenjelwa isignali ukuguqulwa. Okuphansi attenuation isici sigcwalisa jikelele isithombe esihle ngesikhathi operation (<2.5 Dbl). Compact, isikhala-ukonga kanye-asebenziseka kalula kudivayisi ivamile phakathi abaklami.
With ukuthuthukiswa yokukhiqiza ubuchwepheshe multi - futhi demultiplexers ubelokhu ngendlela engaguquguquki mkhuba phansi ku Ubukhulu jikelele, ukukhuphula isivinini uma amasignali ukuguqulela ukunciphisa attenuation futhi ukwandisa nokwethenjelwa ukusebenza kwabo.
