Abstract
The increasing demand on the capacity of the communication system is pushing the industry into more advanced development stage, especially true for SONET/SDH TDM 10Gb/s systems. In addition to the long haul network, there is a big interest in short distance, low cost system suitable for local ring architecture around Metropolitan area. In this talk, we investigate directly modulated 10Gb/s DFB laser based transmitters. Both 1.3 micrometer and 1.55 micrometer DFB lasers are evaluated, including uncooled lasers. Since most of the installed fiber in the U.S. is conventional, non-dispersion shifted fiber, we also focus on chirp induced dispersion penalty using the 1.55 micrometer laser. Their performance is compared with some externally modulated transmitters, and experiments are conducted for transmitting over non-dispersion shifted fiber.
