Yini i-edfa amplifier

I-Edfa (I-Erbium-doped fiber amplifier), okokuqala yasungulwa ngo-1987 ngokusetshenziswa kwezentengiselwano, iyi-amplifier esetshenzisiwe kakhulu yohlelo lwe-DWDM elisebenzisa i-Erbium-Doped Fiber njenge-Optical Doped Fiber njenge-Amplical Amplification Meyials ngokuqondile. Inika amandla okwandulelwa okusheshayo kwezimpawu ezinama-wavelength amaningi, ngokuyisisekelo ngaphakathi kwamabhendi amabili. Enye iyisivumelwano esijwayelekile, noma i-C-band, cishe kusuka ku-1525 nm kuya ku-1565 nm, kanti enye iyona ende, noma i-L-band, cishe kusuka ku-1570 nm kuya ku-1510 nm kuya ku-1510 nm kuya ku-1510 nm. Ngaleso sikhathi, inamabhendi amabili asetshenziswa ngokuvamile, 980 nm no-1480 nm. I-980NM Band inesigaba esiphakeme esiphakeme esivame ukusetshenziswa kuhlelo lokusebenza lomsindo oluphansi, kanti i-1480NM band inesigaba esiphansi kodwa esibanzi esibanzi sesiphambano esisetshenziselwa ama-amplifiers aphezulu.

Lesi sibalo esilandelayo sibonisa imininingwane ka-Edfa Amplifier kanjani ukuthuthukisa amasiginali. Lapho i-Edfa Amplifier isebenza, inikeza i-laser yepompo nge-980 NM noma 1480 NM. Lapho nje i-laser yepompo nezimpawu zokufaka zidlula nge-coupler, zizobe zingezelwe ngaphezulu kwefayibha ye-erbium-doped. Ngokusebenzisana nge-doping ion, ukukhuliswa kwesiginali kungagcinelwa ekugcineni. Lokhu konke-oku-amplifier okubonakalayo akutholi kakhulu kuphela izindleko kodwa kuthuthukisa kakhulu ukusebenza kahle kokukhuliswa kwesiginali ye-Optical. Ngamafuphi, i-Edfa Amplifier iyingqophamlando emlandweni we-Fiber Optics engakhulisa ngokuqondile amasiginali ngama-wavelength amaningi ngaphezulu kwefayibha eyodwa, esikhundleni sokukhuliswa kwesiginali okukodwa.

I-Beijing Rofea Optoelectronics CO, LTD etholakala "Silicon Valley" - I-Beijing Zhongguantun, ibhizinisi eliphakeme elinikezelwe ekusebenzeni kwezikhungo ezizimele nezingaphandle, i-Design kanye ne-Enterprise Yemikhiqizo ye-Optoelectronic, futhi inikezela ngezixazululo ezintsha kanye nokwenziwe ngezifiso Izinsizakalo zabaphenyi besayensi kanye nonjiniyela bezimboni. Ngemuva kweminyaka yokuqamba ama-Independent Innovation, kwakha uchungechunge olucebile futhi oluphelele lwemikhiqizo ye-Photoelectric, esetshenziswa kakhulu, i-2016 yanqoba isitifiketi se-Beijing High-Tech Enterprise, inezitifiketi eziningi ze-Patent, ziqinile Amandla, imikhiqizo ethengiswayo ezimakethe nasemazweni aphesheya, ngokusebenza kwayo okuzinzile, okuphezulu ukunqoba ukudunyiswa kwabasebenzisi ekhaya nakwamanye amazwe!
