Uncooled direct modulation of a 1.55 micrometers distributed feedback (DFB) laser is demonstrated at 10 Gbit/s is demonstrated. The small signal performance of the laser at 25 degree(s)C gives rise to a -3 dB bandwidth in excess of 9 GHz, reducing to 8 GHz at 55 degree(s)C. Under uncooled, direct modulation at 10 Gbit/s the back-to-back eye diagrams obtained at temperatures up to 55 degree(s)C are found to be open, with extinction ratios of 6 dB for a peak-to-peak current swing of 40 mA. Transmission at 10 Gbit/s over standard singlemode fiber, is demonstrated over 12 km with the uncooled device. Using this device, multi-level coding is demonstrated at 20 Gb/s, and transmission at 5 Gb/s over 700 m of multi-mode fiber at 60 degree(s)C.
