Semi-blind Nonlinear Equalization in Coherent Multi-Span Transmission System with Inhomogeneous Span Parameters
Fiber optics communications Coherent communications
2010/6/8
Semi-blind sequence is proposed for optimizing the nonlinear equalization parameters from limited prior knowledge of link. Its performance is demonstrated in an extreme case where the fiber type of a ...
Realisation of a real-time 12.1 Gb/s optical OFDM transmitter and its application in a 109 Gb/s transmission system with coherent reception
optical OFDM transmitter transmission system
2009/7/20
For the first time a realisation of a real-time 12.1 Gb/s FPGA-based O-OFDM transmitter is demonstrated (Q=19.1 dB) and successfully applied in a 9x12.1 Gb/s transmission over 400 km SMF.
Cascaded Phase-Preserving Amplitude Regeneration in a DPSK Transmission System
Cascaded Phase-Preserving DPSK Transmission System
2009/7/15
Experimental results obtained on 10 Gb/s RZ-DPSK transmission in a recirculating fiber-loop setup show that nonlinear amplifying loop mirrors can efficiently enhance system performance. Main limiting ...
Review of 20 years of undersea optical fiber transmission system development and deployment since TAT-8
undersea optical fiber transmission system development
2008/7/30
TAT-8 was the first optical transatlantic undersea system, starting a dramatic expansion of the global telecommunications network. This paper reviews the drivers and products that emerged since TAT-8 ...
