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 x 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) * Optical output power: Pf = 10 mW MIN. * Available for DWDM wavelengths based on ITU-T recommendations (50 GHz grid) * 4-channel wavelength tunable capability for 50 GHz-spacing (NX8571SxxxxD) * Internal thermo-electric cooler and isolator * Hermetically sealed 14-pin butterfly package * Polarization maintain fiber pigtail
