Abstract
A narrowband optical amplifier ("amplet") is proposed and demonstrated that can be constructed into an amplifier-based subsystem to perform dispersion compensation and dynamic power management in a wide DWDM bandwidth. The amplet is designed to inherently provide two important networking features: narrowband accessibility and bandwidth scalability. The narrowband accessibility allows for the realization of inline dispersion compensation and dynamic gain management; and the bandwidth scalability provides an economic solution to meet capacity demand. As a demonstration, a modular bandwidth management subsystem is developed using this amplet technology to simultaneously provide dispersion compensation, dynamic power management, and amplification. The experimental results show that wide band dynamic gain control is achieved using this new bandwidth management architecture. We demonstrate system power penalties less than 1 dB using this subsystem in a long-haul system testbed with accumulated dispersion varying from -600 to -1600ps/nm.
