Abstract

In this work we experimentally demonstrate record 579.5km commercial unrepeatered 2.5G transmission, with the first application of 2.5Gb/s polarization multiplexed quadrature phase shift keyed (PM-QPSK) format combined with a coherent receiver. Such ultra-long haul is enabled by use of Forward Error Correction(FEC), PM-QPSK transponders, ultra-low loss (ULL) fiber, and optimization of remotely pumped optical amplifiers (using forward RGU and backward RGU). To the best of our knowledge this is the longest unrepeatered 2.5G-based transmission distance reported to date.
