首页 Semiconductor Diodes DFB Laser Diode 1530-1565nm DFB laser diode Single mode DFB laser 1550nm 10/30mW (14 pin butterfly package 2.5G communication specific) 1550nm 30mW single mode DFB laser

    • 1550nm 30mW single mode DFB laser

    With optimized optical properties, 1550nm single-mode DFB is an ideal choice for demanding sensing system applications. The innovative chip design has suppressed high-order longitudinal and transverse modes while maintaining linear polarization stability. The laser has high output power, narrow line width and good consistency and is currently favored by domestic scientific research customers. At present, our existing inventory wavelengths cover 1000-2400nm. For some specific application areas of customers, we can provide customers with customized chip screening services.
