“…Figure 5 shows the BER characteristics of the fabricated APD-ROSA. Assuming Reed-Solomon (255, 223) forwarderror correction (FEC) [27][28], the error-free condition can be determined at a BER of 10 -3 under a pre-FEC condition. The fabricated APD-ROSA exhibited a minimum receiver sensitivity of -32.7 dBm, even at the transmitter ER of 5.5 dB.…”

We developed a practical high-sensitivity 10-Gbit/s III-V compound-based avalanche photodiode (APD), and an receiver optical subassembly (ROSA) mounting the APD for 10-Gbit/s burst-mode operation. The 10-Gbit/s APD features an inverted p-down structure with a 200-nm InAlAs avalanche layer that produces low excess noise and a low dark current simultaneously at large gain. By combining our APD with a burst-mode trans-impedance amplifier (B-TIA), the resulting APD-ROSA exhibited -32.7 dBm for 10-Gbit/s burst-mode optical signals, which allows for a loss budget exceeding 35 dB on optical access networks such as passive-optical networks.

“…Two fixed upstream and downstream wavelengths are allocated to each user. The Wavelength Division Multiplexed Passive Optical Network architecture can offer more elasticity for network movement and more bandwidth per user than conventional passive optical network based on TDM [2,3]. Bidirectional single fiber PON can reduce the use of fiber links, as well as the number of network equipments, and hence reduce energy consumption and the cost.…”

In this paper, the performance of bidirectional passive optical network with 128 users has been evaluated. The signal is transmitted at 10 Gbps for downstream and upstream transmission up to a distance of 60 km. The splitter is used as a PON element which distributes the data signal and creates a communication between central office and users. The system is investigated at different input power for different number of users and performance is evaluated in terms of Q-factor and BER. In downstream transmission, the quality factor of 5.94 and bit error rate of 1.33e-9 is achieved whereas in upstream transmission the quality factor of 6.30 and bit error rate of 1.44e-10 is achieved at an input power of -15 dBm with bit rate of 10 Gbps up to a distance of 60 km.

“…A PON is point-to-multipoint optical network in which passive splitters are used to connect a single Optical Line Termination (OLT) to many users. In such a context, Forward Error Correction (FEC) were recently introduced to compensate the signal degradation due to low cost optical components and to increase the number of users connected to the same OLT [5]. In PONs, even if decoding performance constraints are not as strict as in OTN, increasing the coding gain reduces the cost of the infrastructure per user.…”

International audienceIn this paper, we demonstrate the higher hardware efficiency of Reed-Solomon (RS) parallel turbo decoding compared with BCH parallel turbo decoding. Based on an innovative architecture, this is the first implementation of fully parallel RS turbo decoder. A performance analysis is performed showing that RS block turbo codes (RS-BTC) have decoding performance equivalent to Bose Ray-Chaudhuri Hocquenghem-block turbo codes (BCH-BTC). A ratio between the decoder throughput and the decoder area is used to show the higher efficiency of the RS full parallel turbo decoder. Finally an implementation of a (31,29)2 RS block turbo decoder on a high performance board including 6 Xilinx Virtex5 FPGAs is detailed. The resulting turbo decoder has an information throughput above 6 Gb/s while the working frequency is only 45 MHz. It shows that RS BTC are an attractive solution for low cost Gb/s fiber optical communications
