“…Therefore, the number of pilot symbols that are required for a reliable estimation of the phase shift is important, to determine the overhead of the algorithm. To evaluate the performance of the algorithm, a model was , to 20.5 dB, which corresponds to a BER of 5 10  . For the low phase noise case, it can be seen that for 50 and 100 symbols, the phase error is kept below 1% even for low SNR values.…”

“…Another possibility for scaling the bit rate is moving to advanced modulation formats, like OFDM. 40 Gb/s OFDM-PON in a single wavelength have been demonstrated with both coherent [4] and direct detection [5]. Very good receiver sensitivity is achieved in the coherent case, but for direct detection there is significant power penalty.…”

“…In the implementation of high speed access networks like 40 Gbps, 100 Gbps or more, chromatic dispersion (CD) and polarization mode dispersion (PMD) are becoming as a limiting factor and restricts the maximum achievable transmission distance (Qian et al 2011). Hence compensation of different fiber dispersions is necessary for the implementation of point to multipoint PONs.…”

This paper demonstrates 100 Gbps long reach coherent passive optical network (CPON) downstream transmission on a single wavelength over 100 km with 1:128 power split having acceptable performance. Here dual polarization-quadrature phase shift keying modulation format is utilized for transmission in the central office and digital signal processing (DSP) is utilized at the optical network unit (ONU) to compensate the linear impairments generated due to high speed optical signal transmission over standard single mode fiber. At the receiving end (ONU), homodyne coherent detection is utilized. The DSP is done using MATLAB and executes five functions that are analog to digital conversion, chromatic dispersion compensation, polarization demultiplexing, carrier phase estimation and digital to analog conversion. The results of proposed architecture are verified in terms of constellation diagrams and receiver sensitivity. The simulated results indicate that our proposed 100 Gbps long reach CPON downstream transmission is feasible and may be implemented in next generation high speed PONs.Keywords Coherent passive optical network (CPON) Á Dual polarization-quadrature phase shift keying (DP-QPSK) Á Digital signal processing (DSP) Á Central office (CO) Á Optical network unit (ONU)

“…This technology spoils the passivity of the optical access network and can't achieve the flexible length of the access span. And the OFDM PON system is so complicated to implement [3]. Therefore, the full-system of 40G PM-QPSK PON will be investigated.…”

In this paper, the system scheme of the 40G long rich coherent PON is stated and the performance of this PON system has been investigated. Based on the analysis of the requirements for NG-PON and the characteristics of various potential NG-PON schemes, it is believed that 40G PM-QPSK coherent PON will be one of the most promising candidate NG-PON schemes for different application scenes in the near future. Since the coherent received PON is the reliable solution for the far future to satisfy the requirements of ultra-high capacity, higher split ratio, and dynamic access distance. The key performance of 40G bps transmission in the downlink and 10G bps transmission in the uplink are also described to certify the rationality of the system.
