Taw qhia ntawm erbium-doped fiber ntau lub zog
Lub erbium-doped fiber amplifier (EDFA, lub teeb liab kho qhov muag teeb ua ke sib txuas ntawm cov erbium ion Er3 + hauv cov tub ntxhais los ntawm lub teeb liab kis) yog thawj qhov kho qhov muag kom nrov dua tsim los ntawm University of Southampton xyoo 1985. Nws yog qhov kev sib txuas lus fiber ntau tshaj. Ib qho ntawm qhov kev tsim muaj. Lub erbium-doped fiber yog lub fiber uas qhov me me ntawm lub ntiaj teb tsis tshua muaj keeb erbium (Er) ions raug doped rau hauv quartz fiber, uas yog qhov tseem ceeb ntawm erbium-doped fiber amplifier. Txij li xyoo 1980s, kev tshawb fawb ua haujlwm ntawm erbium-doped fiber amplifiers tau txuas ntxiv ua cov kev sib tawg loj. WDM thev naus laus zis ntau ntxiv qhov peev xwm ntawm kev sib txuas lus fiber ntau. Nws tau dhau los ua qhov feem ntau siv cov kho qhov muag txuas ntxiv hauv cov hluav taws xob optic sib txuas lus.
