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 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-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 yebhizinisi. onjiniyela.Ngemva kweminyaka yokusungula izinto ezizimele, sekwakhe uchungechunge olucebile noluphelele lwemikhiqizo kagesi, esetshenziswa kakhulu kumasipala, ezempi, ezokuthutha, amandla kagesi, ezezimali, ezemfundo, ezokwelapha kanye nezinye izimboni.Izinzuzo ezinkulu embonini, njengokwenza ngokwezifiso, ukuhlukahluka, ukucaciswa, ukusebenza kahle okuphezulu, isevisi enhle kakhulu.Futhi ngo-2016 wawina i-se Beijing amandla kagesi, imikhiqizo eminingi ye-pacert yasekhaya, imikhiqizo eminingi ye-pacert yase-Beijing yathengiswa, i-pricet yasekhaya yathengiswa kakhulu kanye nezimakethe zaphesheya, ngokusebenza kwayo okuzinzile, okuphakeme ukuzuza ukudunyiswa kwabasebenzisi ekhaya naphesheya!
