1550nm Sab Nraum Zoov Laser Khoos Hloov Qeb
1550nm Sab Nraud Laser Optical Transmitters tau thov nyob rau hauv ntau txoj kev xa mus, lub suab seev chirp yuav hnov mob nrog rau qhov txuas dispersion ntawm lub fiber. Yuav muaj kev cuam tshuam ntawm cov txais. Yog tias ua haujlwm nrog EDFA, yuav muaj qhov tsis txaus ntseeg ntawm CSO. Txoj kev faib tawm thiab teeb meem tsis zoo yuav ntxiv nrog qhov kev ncua ntev thiab ntau dua.
1550nm Internal modulation CATV optic transmitter, muaj cov chirp thiab dispersion raug them nyiaj sab hauv, thiab txhim kho qhov system index tau zoo heev. Nws tuaj yeem siv hauv lub nroog uas cov nyiaj tsis txaus thiab qhov kev coj deb yog tsawg dua 10Km ua qhov kev hloov kev hloov.
Ntseg
Tsawg chirp effect, high linearity DFB laser
Dual Module yog li tsav, chirp them Laser OMI AGC / MGC
Qhov khoom qhia tus tes hloov qhov teeb meem
Muab fais fab mov sab hauv thaub qab. Puv-hloov pauv puv-tswj kev tswj ntawm qhov kub thiab txias
