Uhlobo oluqhelekileyo lwei-amplifier yokukhanyaisetyenziswa kunxibelelwano lwe-optical
Xa imiqondiso ye-optical idluliselwa kwiifayibha ze-optical, njengoko umgama usanda, imiqondiso ye-optical iya kuba buthathaka kancinci kancinci ize ibangele ukuphazamiseka konxibelelwano… Kude kube kuvele ii-optical amplifier, zifana “nesikhululo sepetroli”, zigcwalisa amandla emiqondiso ye-optical ukuze zikwazi ukuthutha idatha ngokulula ukuya kwindawo eziya kuyo. Le ngxaki iza kukwazisa i-optical amplifier eqhelekileyo kunxibelelwano lwe-optical – ii-amplifier yefayibha efakwe i-erbium(i-EDFA optical amplifier).
I-amplifier yefayibha efakwe i-erbium, njengoko igama lisitsho: I-Erbium (Er), into enqabileyo yomhlaba, ifakwa kwifayibha ye-quartz. Xa isignali ye-optical yokufaka idlula kwifayibha efakwe i-erbium, ii-ion ze-erbium ezintathu (Er³⁺) ziya kutsala amandla okukhanya kwepompo kwaye zitshintshele kwinqanaba eliphezulu lamandla. Inani lamasuntswana akwimeko enomdla liyaguqulwa. Phantsi kokungeniswa kokukhanya kwesignali yokufaka, ii-ion ze-rare earth ezinomdla zomhlaba ezikhutshwayo ziyakhutshwa kwaye zikhuphe ii-photons ze-frequency efanayo nokukhanya kwesignali, ngaloo ndlela zifezekisa ukwandiswa kwe-optical.
Izinto ezenza iI-amplifier ye-EDFA yokukhanyangokubanzi ziquka ii-optical couplers (ezidla ngokusebenzisa ii-wavelength division multiplexers WDM), ii-optical isolators, ii-erbium-doped fibers, ii-filters, kunye nemithombo yepompo. Phakathi kwazo, i-optical coupler idibanisa ngobuchule ukukhanya kokufaka kunye nokukhanya kwepompo ukuqinisekisa ukuba isignali ifakwe ngokuchanekileyo kwi-erbium-doped fiber; indima ye-optical isolator kukucinezela ukukhanya okungenamsebenzi kwindlela ye-optical ukuthintela ukwenzeka kwemiqondiso yokuphazamiseka okungafunekiyo, ukuqinisekisa ukuhanjiswa kwesignali kwicala elinye; i-optical filter isusa ingxolo engafunekiyo ukuphucula umlinganiselo wesignali-kwingxolo kunye nokuqinisekisa ukucaca kokudluliselwa kolwazi.
Okwangoku, abaphandi baphuhlisa ii-amplifiers zefayibha ezimbini (i-DBFA) kunye nee-amplifiers ze-ultra-wideband (i-UWOA), bejonge ukwandisa i-gain bandwidth kwi-frequency band ye-wavelength division multiplexing (i-WDM) yonke. Kutshanje, iqela lophando elidibeneyo elivela kumaziko ophando aseYurophu liphuhlise i-traveling wave parametric amplifier esekelwe kwiitships ze-photonic. Ngesakhiwo esincinci, sifezekisa i-ultra-wideband signal amplification, ene-bandwidth ye-140 nm (ephindwe kathathu kune-EDFA yendabuko), kwaye ivolumu incitshisiwe ukuya kwinqanaba leesentimitha, ibonelela ngenkxaso yesantya esiphezulu kakhulu kumaziko edatha kunye ne-AI computing. Ezi "super amplifiers" ziya kuxhasa ukuhanjiswa kwamaza angaphezu kwekhulu kwifayibha nganye, zibeka isiseko sonxibelelwano lwe-holographic kunye neefektri ezikrelekrele kunye nezinye izicelo kwixesha le-6G.
