1547.7nm 20mW DFB激光器 热电制冷 保偏光纤 FC接头
The NX8562 Series is a 1550 nm Multiple Quantum Well (MQW) structured Distributed Feed-Back (DFB) laser diode module with Polarization Maintain Fiber (PMF). It is designed as Continuous Wave (CW) light source and ideal for optical transmission systems with external modulators. The device is available for Dense Wavelength Division Multiplexing (DWDM) wavelengths based on ITUT recommendations, enabling a wide range of applications. FEATURES
• Output power Pf = 20 mW MIN.
• Available for DWDM wavelengths based on ITU-T recommendations
(100 GHz grid, refer to the ORDERING INFORMATION)
• Internal thermo-electric cooler and isolator
• Hermetically sealed 14-pin butterfly package
