Abstract: In a coarse wavelength division multiplexing (CWDM) optical transmission system, a distributed feedback (DFB) laser is tuned so that the peak reflection of the grating overlaps with the gain range of the DFB laser. The diffraction grating is tuned so that the peak is positioned on the long wavelength end of the gain spectrum at a selected temperature. The optical transmission system operates in an environment having a wide temperature range (i.e., about −40° C. to about 85° C.). Heat is applied to the laser and as the laser temperature increases, the gain range overtakes the grating peak. When the gain range and the grating peak overlap at increased laser temperature, laser output is improved.

Abstract: A plug-in, optical add/drop (OAD) device includes a filter for adding and dropping a light beam of wavelength (λk) from a combined light beam having individual beams of different wavelengths (λ1 . . . n). Several devices can be selectively integrated to create an optical communications system that will handle “n” different optical communications circuits. In operation, the devices are individually connected (plugged-in) to a GBIC, and they are serially connected (plugged-in) to each other. Consequently, immediately upstream from a device, the combined light beam includes wavelengths (λ1 through λn). On the other hand, the combined light beam immediately downstream includes (λ1 through λk−1 and λk+1 through λn).
