4×43Gb/s unrepeatered transmission over 525km using PDM-RZ-BPSK with a coherent receiver
19 September 2010
We demonstrate the transmission of 4 channels at 43Gb/s over a record 525km unrepeatered distance using PMD-tolerant and spectrally efficient PDM-RZ-BPSK modulation combined with a coherent receiver, advanced third order Raman and remote amplification technologies and large effective area fibre.
