Narrow linewidth, typical line width 1 MHz. With SC/APC SM fiber connector. Laser Set Temperature: 30 - 45 C (Not popular 25 C). P/N: NX8563LAxxx-88E or NX8563LAxxx-88C. INTP/INTS: NX8563LAxxx-88E-AZ or NX8563LAxxx-88C-AZ. Pf=10mW. We checked the package, laser module physical details, manufacture test data, and our lab test result, there is no difference between -88E and -88C in P/N.
For direct modulation. The datasheet in the pdf link below is focus on DWDM application, but it can be also for CATV. From http://www.cel.com/prod/prod_laser.asp , this laser model is described as "NEC's Direct Modulated InGaAsP MQW DFB Laser Diode Module for 2.5Gb/s 110km and 240km Reach DWDM Metro and CATV Applications ". See txt link below for more info for CATV application.
