The chirp managed laser (CML) is an alternative transmitter technology that allows a directly modulated laser (DML) to be used in high-performance applications with a smaller size, lower power consumption, less device complexity, and lower cost. The CML comprises a DML and an isolated, passive optical filter. A key feature of the CML is its large tolerance to fiber dispersion, reaching over 360 km...
We report the first long-haul DWDM transmission using three chirp-managed lasers spaced 50-GHz apart in SSMF at 10-Gb/s. Transmission penalties less than 0.7 dB over a dispersion-managed 1980-km link was measured with performance comparable to NRZ-OOK.
