We demonstrate the longest unrepeatered and uncompensated SOA-based transmission of 16times10 Gbit/s channels over 140 km single mode (G.652) fiber. We exploit the DPSK modulation format, two commercial SOA devices and a frequency-periodic narrow optical filter.
Significant progress in undersea transmission can be made with the use of new modulation formats. High OSNR sensitivity and nonlinear tolerance to dispersion of RZ-DPSK modulation may lead to cost-efficient 10 and 40 Gb/s systems.
We investigate optimal dispersion maps for 40 Gbit/s DWDM systems based on return-to-zero differential phase-shift-keying modulated channels. Accumulating the dispersion compensation in 150 km G.652 units leads to a small transmission penalty of less than 0.5 dB.
