Indlela yokukhetha uhloboumgca wokulibaziseka we-opticalI-ODL
Imigca yokuLibaziseka kwe-Optical (I-ODL) zizixhobo ezisebenzayo ezivumela imiqondiso ye-optical ukuba ingene kwisiphelo sefayibha, idluliselwe kubude obuthile bendawo ekhululekileyo, ize iqokelelwe kwisiphelo sefayibha ukuze iphume, nto leyo ebangela ukulibaziseka kwexesha. Zingasetyenziswa kwiinethiwekhi zonxibelelwano ezikhawulezayo ezifana ne-PMD compensation, ii-interferometric sensors, ii-coherent telecommunications, ii-spectrum analyzers, kunye neenkqubo ze-OCT.
Ukukhetha okufanelekileyoumgca wokulibaziseka we-fiber optickufuna ukuqwalaselwa kwezinto ezininzi, kubandakanya ixesha lokulibaziseka, i-bandwidth, ilahleko, iimeko zokusingqongileyo, kunye neemfuno ezithile zesimo sesicelo. Nazi ezinye iindlela ezibalulekileyo kunye nezinto ekufuneka uziqwalasele ukuze ukhethe i-intanethi efanelekileyo.umgca wokulibaziseka kwefayibha:
1. Ixesha lokulibazisa: Chonga ixesha lokulibazisa elifunekayo ngokusekelwe kwimeko ethile yesicelo.
2. Uluhlu lweBandwidth: Ii-aplikeshini ezahlukeneyo zinokuba neemfuno ezahlukeneyo ze-bandwidth. Umzekelo, iinkqubo zonxibelelwano zihlala zifuna i-bandwidth ebanzi, ngelixa ezinye iinkqubo zeradar zinokufuna kuphela imiqondiso ngaphakathi koluhlu oluthile lwefrikhwensi. Ukongeza, kuyimfuneko ukuqwalasela iimpawu ezahlukeneyo ze-bandwidth ze-single-mode fiber kunye neentlobo ze-multi-mode fiber. I-single mode fiber ifanelekile kwii-applications ze-long-mode kunye ne-high bandwidth, ngelixa i-multimode fiber ifanelekile kwii-applications ze-short middle.
3 Iimfuneko zokulahlekelwa: Misela ilahleko ephezulu evumelekileyo ngokusekelwe kwiimfuno zokusetyenziswa. Kwiizicelo ezisebenzayo, iifayibha ze-optical ezilahlekileyo kancinci kunye nezihlanganisi ezikumgangatho ophezulu ziya kukhethwa ukunciphisa ukuncitshiswa kwesignali.
4 Iimeko zendalo: Ezinye izicelo zingafuna ukusebenza kumaqondo obushushu aphezulu, ngoko ke khetha iifayibha ezibonakalayo ezinokusebenza ngokuqhelekileyo ngaphakathi koluhlu lobushushu oluchaziweyo. Ukongeza, kwiindawo ezithile, iifayibha ezibonakalayo kufuneka zibe namandla athile oomatshini ukuthintela umonakalo.
5. Uhlahlo lwabiwo-mali lweendleko: Khetha imigca yokulibaziseka ye-optic engabizi kakhulu ngokusekelwe kuhlahlo lwabiwo-mali. Imigca yokulibaziseka yefayibha esebenza kakuhle inokuba nexabiso eliphantsi, kodwa iyimfuneko kwezinye iinkqubo ezibalulekileyo.
6 Iimeko ezithile zesicelo: Qonda iimfuno ezithile zesimo sesicelo esithile, njengokuba kufuneka ukulibaziseka okuhlengahlengiswayo, nokuba eminye imisebenzi (efana nee-amplifier, izihluzi, njl.njl.) kufuneka idityaniswe. Ngamafutshane, ukukhetha ngokufanelekileyo umgca wokulibaziseka we-fiber optic ofanelekileyo kufuna ukuqwalaselwa ngokubanzi kwezinto ezininzi. Siyathemba ukuba la manyathelo kunye nezinto ezingentla zinokukunceda ukhethe umgca wokulibaziseka we-optic ofanelekileyo i-ODL.
