摘要： We demonstrate for the ?rst time an intensity-modulated direct-detection link using four states of polarization. The four data-independent tributaries are each assigned distinct states of polarization to enable the receiver to separate the signals. Polarization rotation due to propagation over optical ?ber is tracked and compensated with simple digital signal processing in Stokes space. Transmission below the forward error correction limit is shown for maximum net bitrates of 100 Gb/s (4 × 27 GBd) and 120 Gb/s (4 × 32 GBd) over 2-km standard single-mode ?ber at a center wavelength of 1550 nm.

Technology Roadmap for Time Division Multiplexed Passive Optical Networks (TDM PONs)
摘要： Commercial passive optical networks (PONs) up to 10 Gb/s have traditionally leveraged mature components from transport and metro transport systems. Starting soon with 25G PON, the data center ecosystem will be leveraged. A strategy to accommodate the higher speed of 25 Gb/s at low incremental cost to 10G PON is presented—essentially to adhere to a simple architecture and to avoid the need for expensive optical amplification. The 25G PON wavelength plan and co-existence scenarios with existing PONs are described. The ability of Time Division Multiplexed (TDM) PONs to address the 5G backhaul, midhaul and fronthaul transport use case is evaluated. The technology roadmap to a future 50G TDM PON is discussed. Analysis of the major challenge, meeting PON loss budgets at 50 Gb/s with higher launch power, is presented, including the cost dependence of transmitter power. This is followed by a short review of research in the field of coherent detection in PON systems, which will be important for 100G PON.

High Speed (100G) Access Networks
摘要： Passive optical networks are currently the most promising solution for access networks. Increasing bandwidth requirements and big data applications need a huge bandwidth. Nowadays, gigabit passive optical networks do not seem to be suitable for these purposes. This paper is focused on describing the development, parameters and needs for High Speed Access Networks (such as 100G EPON). The simulations with current wavelengths plans are presented. For simulations we used VPITransmissionMakerTM 9.7. Our goal was to create a rudimentary bidirectional PON system with one ONU and do several simulation scenarios by arti?cially increasing loss in a splitter for simulating more ONUs. Our following results consist of BER values and eye diagrams for each simulation scenario and proof that 100G EPON networks are most promising networks for the future. We proved that the 100G-EPON networks fully support the basic and currently used split ratios. We also created a two-way communication model and evaluated the obtained data from the bit error-rate and system reach point of view. The entire model was compared with the ?nal version of NG-PON2.
