High Power Tolerant Optical Duobinary Signal Transmission

摘要

We investigated the characteristics of optical duobinary signals in achieving high fiber input power transmis- sion focusing on the idea of optimum residual dispersion equal- ization. We confirm through calculations and experiments that setting the total link dispersion at a non-zero value allows high fiber launched power (+18dBm) and large dispersion tolerance (350psm) at 10Gbit/s.
