Channel bit rates of 40 Gbit/s are the next step after 2.5 and 10 Gbit/s in the SONET/SDH hierarchy. They enable multi Tbit/s transmission of live traffic over a single fiber. All recent optical transmission records concerning aggregate capacitiy per fiber were achieved using this technology. Comparing the limiting effects of 2.5, 10 and 40 Gbit/s system configurations reveals that 40 Gbit/s allows for the longest regenerator free distance on NZDSF. In this paper we describe transmitter and receiver designs as well as results from field trials. The first trial demonstrated a transmission of live traffic with a record aggregate capacity of 3.2 Tbit/s, whereas the second successfully demonstrated a doubling of the channel capacity to 80 Gbit/s using polarization multiplexing with automated polarization control.
