DESCRIPTION
The NX8562LF is a 1 550 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 ITU-
T recommendations, enabling a wide range of applications.
