With wavelength spacing less than 1nm, each LD must provide stable performance in multi-wavelength, multiplexing environments. Wavelength stability and compact design are key parameters for DWDM light sources.
Samples are available off the shelf.
For wavelength monitoring, NEC has devised unique optics that use a Fabry-Perrot etalon filter housed in the package. This results in minimum power loss and eliminates costly external optics required by conventional LDs. Our innovative LD module offers exceptional excellence in wavelength stability and compact design. These features are solid foundations for tomorrow's DWDM systems. All specifications are subject to change without notice.
