Minimum order qty: 5pc, 1549.3nm isolated 14-pin butterfly laser module, Pf>20mW at 167mA. NEC P/N: NX8562LB-493BA, 1MHz linewith.

CW source for external modulator in DWDM systems. Great value for your research project. Made in 2001. Low linewith (1MHz).NEC model: NX8562LB493-BA. wavelength: 1549.3nm. Typical linewidth: 1MHz. 900um-buffered fiber with FC/PC connector. PMF at slow axis is sample verified by fiber scope in our lab. Specification: 20mW output from fiber at less than 167mA. See datasheet in two pdf links below(year 2001 or 2003 version). Sample test sheet by manufacturer in last photo below is not from actual stocked lasers.We have tested all the lasers at our lab, all meet 20mW output at less than 167mA drive current. We can emaill you detailed test reports in MS word for all lasers, see 3 sample test repots below (see better look at last htm link below).Laser Diode Module Verification Data On: February 9, 2009 at our lab.
