20GHz DFB laser
Product introduction:
Based on original design,ORI-DFB-1310A-20 laser has low RIN performance of -155dB/Hz, 55dB side-mode rejection ratio, and wavelength accuracy of +/-1nm.
This DFB laser achieves a 3 dB modulation bandwidth greater than 20 GHz at 60 mA injection current with flat bandwidth and high linearity.
Scope of Application:
This product realizes the direct modulation of wide-band RF signals and is suitable for microwave photonics fields such as the transmission of principal oscillator signals, clock signals, and electro-optical conversion of wide-band RF signals.
