“…A gain tunable erbium-doped fiber amplifier (EDFA) with 5 dB noise factor is employed in the end of OLT to adjust the power into fiber. At each of the ONU receiver there is a variable optical attenuator (VOA) to adjust the received power for sensitivity measurement and to simulate the loss corresponding to power-splitting [4] [5]. The measured bit error rate (BER) of the coherent PM-QPSK PON system without the link transmission (B2B) is plotted in Fig.…”

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.

“…For general consideration, NG-PON is expected to provide 40 Gbps bandwidth for at least 128 ONUs, wh ile covering 60-100 km t ransmission distance at the same time [1,2]. With receiver sensitivity approaching to quantum limit and proper DSP algorith m theoretically being capable of compensating any linear penalty, such performance requirements are not difficu lt to fulfil, and the main issue turn out to be the cost and complexity.…”

“…is undisputable. However, current solutions do not seem to adequately address the stringent requirements identified regarding Next Generation Optical Access (NGOA) networks (relevant standards are expected by 2015): Peak bandwidth rates offered per user should be at least 1 Gbps, the architecture should be passive and optically transparent, supporting multi-stage splitting and demonstrating high system/infrastructure sharing (more than 128 users on a single interface) at low power consumption [1].…”
