LASER DIODE

NX8571 Series

1 550 nm CW LIGHT SOURCE

InGaAsP MQW-DFB LASER DIODE MODULE

WITH WAVELENGTH MONITOR

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.

This device 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.

This device is designed as CW light source and ideal for transmission

systems in which external modulators are used.

FEATURES

• Wavelength monitor function (Etalon Filter, Wavelength monitor PD)

• Available for DWDM wavelengths based on ITU-T recommendations

(50 GHz grid)

• 4-channel wavelength tunable capability for 50 GHz-spacing
