As the demand for broadband applications continues rising, low cost and high capacity PON system has attracted more attention to keep up with the increasing demand in the future access network. Recently, the IEEE 802.3 Ethernet Working Group has already sponsored the discussion of next generation Ethernet passive optical network (NG-EPON) to provide 25-Gb/s per wavelength. In order to upgrade current 10-Gb/s PON to realize the capacity of 100 Gb/s PON with 25 Gb/s per wavelength, a variety of experimental demonstrations have shown the feasibility of 25-Gb/s per wavelength using the modulation schemes of four-level pulse amplitude modulation (PAM-4), electrical duobinary (EDB), optical duobinary (ODB) or non-return-to-zero on-off-keying (NRZ-OOK) for high speed transmission. In order to achieve higher performance, these transmission schemes are always combined with the advanced digital signal processing (DSP) which increases the technical complexity and the cost as well. Most of the previous demonstration are based on the off-line processing, therefore requires more time for the practical deployment. In this paper, we demonstrate the first field trial a real-time 100Gb/s TWDM-PON system with 4×25-Gb/s downstream and 4×10-Gb/s upstream transmission using 10G-class directly-modulated lasers (DMLs) and APD/PIN receivers. A single delay-interferometer (DI) is used to achieve frequency equalization as well as chirp management to increase the high frequency components of the system response and combat the chromatic dispersion (CD) during the fiber transmission. Note that there is no DSP applied for the whole system. Electrical clock/data recovery (CDR) chips are integrated on the main board for data generation, recovery and real-time bit error rate (BER) measurement. We obtained a power budget of 33 dB with 0-40km of standard single mode fiber based on NRZ-OOK modulation format for the downstream. The system stability is also verified using deployed 40-km fiber infrastructure over 67-hour real-time measurement.

In today's distributed computing systems, a large amount files contain huge data need to be transferred to their destination as soon as possible or else the quality of these systems will be seriously affected, and these transfer requests arrived dynamically. We propose some effective heuristic algorithm to this problem with the purposes of minimizing the maximal file transmitting time, and we can get some primal results from the algorithm. However, as we known, the problem of routing and scheduling for the dynamic arriving files in the optical network has a large number of constrains and the exact solution is computationally expensive, so it is hard to get the optimal result about this problem and we can not know whether the heuristic results is good or how closed it closed to its optimal result. In order to get some more detail results, we apply the approach called Lagrangian relaxation combined with subgradient-based method and utility the heuristic result to compute the lower bound of the optimal solution, and we consider the optimal target of minimizing the maximal file transmitting complete time for it's an important aspect with the file transmitting problem. We mainly use Lagrangian relaxation (LR) to research the dynamical lager file transmitting problem. Firstly, in order to apply the LR method we formulation our dynamic file routing scheduling and distributing problem in WDM optical network into mathematic model with some corresponding constraints. Secondly, change the formulation with some added variables to let it more suitable for LR and then introduce the Lagrangian multipliers into the model to obtain the Lagrangian function. With this function we can divided it into some small independent problems that could let it be solved more easily and at last we utilize the result received from the heuristic algorithm to solve the Lagrangian multiplier problem with subgradient-based method in order to getting the sharpest possible lower bound. With the comparison of our simulation results, we can prove that the Subgradient algorithm based on LR can get better results of the file transmitting time than the heuristic algorithm, and with the theorem of Lagrangian Bounding Principle we can know that value of LR method is a lower bound on the optimal value.

Many distributed computing applications need transfer large files between distributed locations as fast as possible. A dynamic routing algorithm for optical network is designed to modify existing transfers and spare network resources for new request to satisfy both old and new transfers' requirements. In data intensive application on circuit-switch optical network, light-path resources are scarce and there should be concurrent file transfers competing for the same fibers. In static routing optical network, if new coming file transfer cannot acquire light-path with enough bandwidth, it could only wait for the releasing of current used resources. Due to the waiting, the delay time will be large. So we use our dynamic routing algorithm to schedule and modify existing light-paths, to spare a light-path with enough bandwidth for new coming file. Our optimized target is to make every file finish transferring in less time, so we propose two objectives defined in the paper: one is to make maximal delay time of all tasks less and the other is to make average delay time less. The algorithm proposed has two mainly steps: 1) Routing process; 2) Dynamic routing process. In routing step, when task of file arrives we firstly get k random paths, then use Least Congestion Algorithm (LCA) (or Shortest Path Algorithm (SPA)) to get the primary path P1 of maximal residual bandwidth (RB) from k paths and the alternate path P2 of the second maximal RB. If the bandwidth of P1 is enough for this task, transfer the file in P1 path. If not, we go to the dynamic routing process. In the second process, get all the links of P1 then we change the existing light paths of tasks in the P1 path one by one to their alternative paths until we can get enough bandwidth of P1. In the dynamic routing process, we design two different queuing strategies. The first strategy is First Arrive First Modified (FAFM) strategy, namely we schedule the first arrival task firstly. The other is Larger Bandwidth First Modified (LBFM) and the file with larger bandwidth is scheduled firstly. By comparison of simulation results, we can prove that our two kinds of dynamic routing algorithms can get better results for both decreasing maximal delay time and average delay time than LCA and SPA routing algorithms. In the two queuing strategies, LBFM can get better results than FAFM strategy. The receivers in the destinations can get better results by using our dynamic routing algorithm.
