The first goal of the project is to identify the modulation schemes that best tolerate a certain level of PMD at 40 Gbit/s and above. The second objective is to develop a dynamic PMD compensator.
Polarization-mode dispersion (PMD) is a key limiter in the deployment of optical systems transmitting at 40 Gbit/s or higher bit rates per channel.
Fiber-based PMD is caused by an asymmetry of the fiber core, in which light polarized in one axis travels faster than light polarized in the other orthogonal axis. This asymmetry of the fiber core can be accidentally introduced in the manufacturing process, and is a permanent feature of the fiber, or can be due to external effects as temperature variations or mechanical stress.
