Kev ua haujlwm siab li 11 dB/mW tau ua tiav los ntawm 1990 nrog 0.98-μm siv. Feem ntau EDFAs siv 980-nm twj tso kua mis lasers rau xws li lasers yog muag thiab muaj peev xwm muab ntau tshaj 100 mW ntawm lub twj tso kua mis zog.
EDFA yog dab tsi hauv kev sib tham?
Erbium-doped fiber ntau amplifier (EDFA) yog ib qho khoom siv kho qhov muag uas siv los txhawb qhov kev siv ntawm cov teeb liab kho qhov muag tau nqa los ntawm kev sib txuas lus fiber ntau.
Lub wavelength twg yog qhov tsim nyog tshaj rau kev siv EDFA?
Ob lub wavelengths ib txwm los tso rau EDFA yog 980 lossis 1480 nm. Thaum lub EDFA yog pumped ntawm 1480 nm, Er ion doped nyob rau hauv lub fiber absorbs lub twj tso kua mis lub teeb thiab zoo siab rau ib tug zoo siab lub xeev (Excited xeev 1 nyob rau hauv daim duab 3).
Dab tsi rov qab tso rau hauv EDFA?
Nrog rov qab tso tawm, EDFA tuaj yeem muab lub teeb liab siab dua lub zog ntawm qhov tso zis, tab sis rau pem hauv ntej ASE suab nrov kuj tuaj yeem siab. Cov suab nrov rov qab ASE hauv kev teeb tsa rov qab tso tawm yog qhov qis ntawm sab nkag ntawm erbium-doped fiber ntau.
EDFA yog dab tsi thiab nws ua haujlwm li cas sau luv?
Feem ntau, EDFA ua haujlwm ntawm lub hauv paus ntsiab lus ntawm stimulating cov emission ntawm photons. Nrog EDFA, ib qho erbium-doped optical fiber nyob rau hauv cov tub ntxhais yog pumped nrog lub teeb los ntawm laser diodes. … EDFA amplification tshwm sim raws li lub twj tso kua mis laser excites lub erbium ions, uas ces mus txog qib siab zog.
