DFB Laser Diode (Distributed Feedback Laser Diode) yog ib hom laser feem ntau siv hauv kev sib txuas lus kho qhov muag thiab kho qhov muag fiber ntau.
Nws txoj hauv kev ua haujlwm yog raws li lub tswv yim ntawm Kev Tshaj Tawm Tshaj Tawm, los ntawm kev qhia txog kev hloov pauv hloov pauv ntawm cov khoom siv semiconductor, kom ua tiav cov teeb pom kev zoo laser nyob rau hauv ib hom longitudinal.
Peb tuaj yeem muab kev daws teeb meem ntawm laser diode, feem ntau peb muab 14 PIN npauj npaim laser diode.
Khoom nta
- DFB nti;
- Wavelength (1270nm, 1290nm…1610nm, 1650nm);
- Low Power (>10mW, 20mW, 40mW);
- Multi-Quantum Well (MQW) active txheej;
- Built-in Isolator (ob theem), TEC, Rth thiab PD;
- FC / APC Connector;
- Tsim los rau Telcordia-GR468.
Qhov siab tshaj qhov ntsuas
Kev ntxhov siab ntau dhau ntawm qhov kev ntsuas siab tshaj plaws tuaj yeem ua rau muaj kev puas tsuaj mus tas li rau lub cuab yeej. Cov no yog cov kev ntsuas kev ntxhov siab nkaus xwb. Kev ua haujlwm ntawm lub cuab yeej tsis cuam tshuam rau cov no lossis lwm yam xwm txheej ntau dhau ntawm cov uas tau muab rau hauv cov haujlwm ua haujlwm ntawm cov ntaub ntawv. Kev raug rau qhov kev ntsuas siab tshaj plaws yuav ua rau muaj kev puas tsuaj mus tas li thiab / lossis cuam tshuam rau kev ntseeg tau ntawm lub cuab yeej.
