LASER DIODE NX8570 Series 1 550 nm CW LIGHT SOURCE InGaAsP MQW-DFB LASER DIODE MODULE WITH WAVELENGTH MONITOR DESCRIPTION The NX8570 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 = 20 mW MIN. • Available for DWDM wavelengths based on ITU-T recommendations (50 GHz grid) • 4-channel wavelength tunable capability for 50 GHz-spacing (NX8570S××××D) • Internal thermo-electric cooler and isolator • Hermetically sealed 14-pin butterfly package • Polarization maintain fiber pigtail Document No. PL10135EJ03V0DS (3rd edition) Date Published June 2004 CP (K) The mark shows major revised points. © NEC Compound Semiconductor Devices, Ltd. 2002, 2004 NX8570 Series PACKAGE DIMENSIONS (UNIT: mm) 15.24 2.54 21.8±0.3 8 φ 6.0±0.2 1 14 #7 + – Cooler 12.7±0.2 φ 0.9 8.89±0.13 10 MIN. 1.25 7 φ 5.0 TOP VIEW 1.0 0.8 #1 PD (Pf) Thermistor PD (λp) LD #8 #14 4– φ 2.67 0.5 20.83±0.25 26.04±0.25 PIN CONNECTIONS 1 2 3 4 5 6 7 5.15 29.97±0.25 Function Pin No. 1.0 0.3 8.2±0.2 5.4 Optical Fiber (PMF) Length: 1 000 MIN.
