Yini i-EDFA Amplifier?

I-EDFA (Erbium-doped Fiber Amplifier), eyasungulwa okokuqala ngo-1987 ukuze isetshenziselwe ukuhweba, iyisikhulisamandla esisetshenziswa kakhulu sohlelo lwe-DWDM esebenzisa i-Erbium-doped fiber njengendlela yokukhulisa i-optical ukuze kuthuthukiswe amasignali ngokuqondile.Inika amandla ukukhuliswa okusheshayo kwamasignali anamaza amaza amaningi, ngokuyisisekelo ngaphakathi kwamabhendi amabili.Enye i-Conventional, noma i-C-band, cishe isuka ku-1525 nm kuya ku-1565 nm, kanti enye i-Long, noma i-L-band, cishe isuka ku-1570 nm kuya ku-1610 nm.Khonamanjalo, inamabhendi okumpompa amabili ajwayele ukusetshenziswa, angu-980 nm no-1480 nm.Ibhendi engu-980nm inesigaba esiphambanayo sokumuncwa esiphezulu esivame ukusetshenziswa kuhlelo lokusebenza olunomsindo ophansi, kuyilapho ibhendi engu-1480nm inesigaba esiphambanayo esiphansi kodwa esibanzi esivame ukusetshenziselwa izikhulisamandla zamandla aphezulu.

Isibalo esilandelayo sibonisa kabanzi ukuthi i-EDFA amplifier ithuthukisa kanjani amasiginali.Lapho i-EDFA amplifier isebenza, inikeza i-laser yepompo eno-980 nm noma i-1480 nm.Uma i-laser yepompo kanye namasiginali okokufaka edlula ku-coupler, azophindwaphindwa phezu kwefayibha ye-Erbium-doped.Ngokusebenzisana nama-ion doping, ukukhulisa isignali kungafinyelelwa ekugcineni.Le amplifier ye-all-optical agcini nje ngokukwehlisa kakhulu izindleko kodwa ithuthukisa kakhulu ukusebenza kahle kokukhulisa isignali yokubona.Ngamafuphi, i-EDFA amplifier iyingqopha-mlando emlandweni we-fiber optics engakwazi ukukhulisa ngokuqondile amasignali ngamaza angamaza amaningi phezu kwefayibha eyodwa, esikhundleni sokukhulisa isignali ye-optical-electrical-optical.

I-Rofea Optoelectronics inikezela ngomugqa womkhiqizo wamamojula wezohwebo we-electro-optic, ama-modulator wesigaba, ama-photodetectors, imithombo yokukhanya kwe-laser, ama-dfb lasers, ama-optical amplifiers, ama-EDFAs, i-SLD laser, i-QPSK modulation, i-pulse laser, i-light detector, i-photodetector ebhalansi, i-Semiconductor laser, i-laser driver ,i-fiber coupler,i-pulsed laser,i-fiber optic amplifier,imitha yamandla okukhanya,i-broadband laser,i-Tunable laser,i-optical delayelectro optic modulator,I-Optical detector,I-Laser diode driver,I-Fiber amplifier,i-erbium doped fibre amplifier,umthombo wokukhanya we-laser,I-laser yomthombo wokukhanya.Siphinde futhi sinikeze amamojula athile ukuze enze ngendlela oyifisayo, njengamamodulators wesigaba esingu-1*4, i-Vpi ephansi kakhulu, kanye namamodulator wesilinganiso sokuqothulwa okuphezulu kakhulu, asetshenziswa kakhulu emanyuvesi nasezikhungweni. i-electro-optic bandwidths efika ku-40 GHz ngokufaka okuphansi Ukulahlekelwa, i-Vp ephansi, i-PER ephezulu.Ifanele izinhlelo zokusebenza ezihlukahlukene kusuka kuzixhumanisi ze-analog RF kuya kwezokuxhumana ezinesivinini esikhulu.
