1 / 7 page NEC's CW InGaAsP MQW DFB LASER DIODE MODULE FOR DWDM APPLICATIONS (20 mW MIN) NX8562 SERIES FEATURES • AVAILABLE FOR DWDM WAVELENGTHS BASED ON ITU-T RECOMMENDATIONS (100 GHz grid) refer to the Ordering Information • OUTPUT POWER: Pf = 20 mW MIN • INTERNAL THERMOELECTRIC COOLER AND ISOLATOR • HERMETICALLY SEALED 14-PIN BUTTERFLY PACKAGE • POLARIZATION MAINTAIN FIBER PIGTAIL NEC's NX8562 Series are a 1550 nm Multiple Quatum Well (MQW) Distributed Feed-Back (DFB) laser diode with Polar- ization Maintain Fiber (PMF). This device is designed as a Continuous Wave (CW) light source and is ideal for optical transmission systems in which external modulators are used. The device is available for Dense Wavelength Division Multi- plexing (DWDM) wavelengths based on ITU-T recommenda- tions, enabling a wide range of applications. DESCRIPTION Notes: 1. Available for DWDM based on ITU-T recommendations. please refer to Ordering Information. 2. Polarization state of LD is aligned parallel to the slow axis.
