Description

The NX8571 Series is a 1 550 nm  Multiple Quantum Well (MQW) structured Distributed Feed-Back  (DFB)  laser diode module with wavelength  monitor function.  The NX8571  is temperature tunable over 4  × 50 GHz channels.  Available at both C-band (1530.334 to 1565.087 nm) and L-band
1565.496 to 1608.760 nm) ITU-T grid wavelengths.

The NX8571  is designed as CW light source and ideal for transmission systems in which external modulators are used.
