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) 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 (NX8571S××××D) Internal thermo-electric cooler and isolator Hermetically sealed 14-pin butterfly package Polarization maintain fiber pigtail Document No. PL10136EJ03V0DS (3rd edition) Date Published June 2004 CP (K) The mark shows major revised points.
