Towards studying cost-effective 100G transport solutions for metro networks, we have assembled a DPSK-3ASK optical modulation and demodulation configuration that operates at a 40Gbaud line-rate, enabled with components from the 40G market. Our architecture has the flexibility to adjust the encoding and modulation scheme, without changes to the physical hardware or architecture, to create for example 86Gb/s DPSK-2ASK or 107Gb/s DPSK-3ASK channels. In this paper we report on optical transmission experiments with DPSK-ASK modulation, specifically 107Gb/s DPSK-3ASK and also 86Gb/s DPSK-2ASK, over standard single-mode fiber (SSMF). Additionally we compare the effects of pulse shaping using a RZ 33% duty-cycle format or a RZ 66% duty-cycle (CSRZ) format.
