Iyini i-EDFA Amplifier

I-EDFA (i-Erbium-doped Fiber Amplifier), eyasungulwa okokuqala ngo-1987 ukuze isetshenziswe kwezentengiselwano, iyi-optical amplifier esetshenziswa kakhulu ohlelweni lwe-DWDM esebenzisa i-Erbium-doped fiber njengendlela yokukhulisa i-optical ukuze ithuthukise ngqo izimpawu. Ivumela ukukhuliswa okusheshayo kwezibonakaliso ezinama-wavelength amaningi, ngokuyisisekelo ngaphakathi kwama-band amabili. Elinye yi-Conventional, noma i-C-band, cishe kusukela ku-1525 nm kuya ku-1565 nm, kanti elinye yi-Long, noma i-L-band, cishe kusukela ku-1570 nm kuya ku-1610 nm. Okwamanje, inama-pumping band amabili asetshenziswa kakhulu, i-980 nm kanye ne-1480 nm. I-980nm band ine-cross-section ephezulu yokumunca evame ukusetshenziswa ekusetshenzisweni komsindo ophansi, kanti i-band ye-1480nm ine-cross-section ephansi kodwa ebanzi yokumunca evame ukusetshenziswa kuma-amplifier anamandla aphezulu.

Isithombe esilandelayo sibonisa ngokuningiliziwe ukuthi i-amplifier ye-EDFA ithuthukisa kanjani izimpawu. Lapho i-amplifier ye-EDFA isebenza, inikeza i-laser yephampu engu-980 nm noma i-1480 nm. Uma i-laser yephampu kanye nezibonakaliso zokufaka zidlula ku-coupler, zizophindaphindwa phezu kwefayibha efakwe i-Erbium. Ngokusebenzisana nama-ion e-doping, ukukhuliswa kwesiginali kungafinyelelwa ekugcineni. Lesi sikhulisi se-all-optical asigcini nje ngokwehlisa izindleko kodwa sithuthukisa kakhulu ukusebenza kahle kokukhulisa isiginali ye-optical. Ngamafuphi, i-amplifier ye-EDFA iyingqophamlando emlandweni we-fiber optics engakhulisa ngqo izimpawu ngama-wavelength amaningi phezu kwefayibha eyodwa, esikhundleni sokukhulisa isiginali ye-optical-electric-optical.

I-Beijing Rofea Optoelectronics Co, Ltd etholakala “eSigodini saseSilicon” saseShayina – eBeijing Zhongguancun, iyibhizinisi lobuchwepheshe obuphezulu elizinikele ekukhonzeni izikhungo zocwaningo zasekhaya nezangaphandle, izikhungo zocwaningo, amanyuvesi kanye nabasebenzi bocwaningo lwesayensi yebhizinisi. Inkampani yethu ihileleke kakhulu ocwaningweni oluzimele kanye nentuthuko, ukuklama, ukukhiqiza, ukuthengisa imikhiqizo ye-optoelectronic, futhi inikeza izixazululo ezintsha kanye nezinsizakalo zobungcweti, ezenzelwe wena abacwaningi besayensi kanye nonjiniyela bezimboni. Ngemuva kweminyaka yokusungula izinto ezintsha ezizimele, yakhe uchungechunge olucebile noluphelele lwemikhiqizo ye-photoelectric, esetshenziswa kabanzi embonini kamasipala, yezempi, yezokuthutha, yamandla kagesi, yezezimali, yezemfundo, yezokwelapha kanye neminye imboni. Izinzuzo ezinkulu embonini, njengokwenza ngokwezifiso, ukuhlukahluka, imininingwane, ukusebenza kahle okuphezulu, insizakalo enhle kakhulu. Futhi ngo-2016 yathola isitifiketi sebhizinisi lobuchwepheshe obuphezulu eBeijing, inezitifiketi eziningi ze-patent, amandla aqinile, imikhiqizo ethengiswa ezimakethe zasekhaya nakwamanye amazwe, ngokusebenza kwayo okuzinzile, okuphezulu ukuze ithole udumo lwabasebenzisi ekhaya nakwamanye amazwe!
