The thesis consists of two different topics: In part 1, the design of an optical system testbed for long haul transmission using a re-circulating loop, is presented. The testbed operates at 40 Gb/s, it simulates an 1800 km link, with optical amplifiers every 80 km, and 16-32 DWDM channels. The theoretical elements involved in the testbed design are reviewed. The optical components are described and selected. The optical system design parameters are presented as well as design targets and optimization parameters. The final implementation is presented and propagation simulations are performed with RZ/NRZ DPSK, QPSK modulation formats to demonstrate the testbed functionality. In part 2 of the thesis, The BER penalty due to PDf in a DPSK demodu...
