Yini i-EDFA Amplifier

I-EDFA (Erbium-doped Fiber Amplifier), eyasungulwa okokuqala ngo-1987 ukuze isetshenziselwe ukuhweba, iyisikhulisamazwi 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 ngokuningiliziwe 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 yephampu namasignali okokufaka edlula ku-coupler, azophindwaphindwa phezu kwefayibha ye-Erbium-doped. Ngokusebenzisana nama-ion doping, ukukhulisa isignali kungafinyelelwa ekugcineni. Lesi sikhulisi se-all-optical amplifier asigcini nje ngokukwehlisa kakhulu izindleko kodwa sithuthukisa 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-Beijing Rofea Optoelectronics Co, Ltd etholakala “eSilicon Valley” yaseChina – Beijing Zhongguancun, iyibhizinisi lobuchwepheshe obuphezulu elizinikele ekukhonzeni izikhungo zocwaningo zasekhaya nezangaphandle, izikhungo zocwaningo, amanyuvesi kanye nabasebenzi bocwaningo lwesayensi. ucwaningo nokuthuthukiswa, ukuklama, ukukhiqiza, ukuthengiswa kwemikhiqizo ye-optoelectronic, futhi inikeza izixazululo ezintsha kanye nezinsizakalo eziqeqeshiwe, ezenzelwe umuntu siqu abacwaningi besayensi nonjiniyela bezimboni.Ngemva kweminyaka yokusungula izinto ezizimele, iye yakha uchungechunge olucebile noluphelele lwemikhiqizo ye-photoelectric, ebanzi kakhulu. esetshenziswa kumasipala, ezempi, ezokuthutha, amandla kagesi, ezezimali, ezemfundo, ezokwelapha nezinye izimboni.Izinzuzo ezinkulu embonini, njengokwenza ngokwezifiso, ukuhlukahluka, ukucaciswa, ukusebenza kahle okuphezulu, isevisi enhle kakhulu.Futhi ngo-2016 wawina ibhizinisi lobuchwepheshe obuphezulu eBeijing. isitifiketi, inezitifiketi eziningi zelungelo lobunikazi, amandla aqinile, imikhiqizo ethengiswa ezimakethe zasekhaya nezaphesheya, ngokusebenza kwayo okuzinzile, okuphakeme ukuze kuzuze ukutuswa kwabasebenzisi ekhaya naphesheya!
