Study of 10G/40G Hybrid Ultra Long Haul Transmission Systems with Reconfigurable OADMs for Efficient Wavelength Usage

We have investigated 10G/40G hybrid ULH transmission systems with OADMs for efficient use of wavelengths, and experimentally demonstrated 10times10 km transmission of 40 Gb/s channels integrated into a 5000 km 10 Gb/s/ch ULH system
