“…We consider this to be because the errors, which exceeded the FEC error correcting capability, have occurred intensively and the FEC could not correct all errors, because Reed-Solomon (255, 239) cannot correct errors longer than 8 byte in a code word. Moreover, it is reported that the burst mode transmission is more likely to have burst errors compared with continuous mode transmission [6]. Therefore, such burst errors longer than 8 byte are likely to be occurred in burst mode transmission, and it occurred at 100 GHz sliced bandwidth in our experiment.…”

Abstract:A simple and scalable wavelength division multiplexing/time division multiple access passive optical network (WDM/ TDMA-PON) system is demonstrated that uses spectral slicing and forward error correction (FEC) with a Reed-Solomon (255, 239) encoder in burst mode upstream transmissions. Receiver sensitivities are improved to −33.5, −34.9 and −35.5 dBm at a sliced bandwidth of 100, 200 and 400 GHz with FEC. Moreover, the dispersion penalties after a 20 km transmission are only about 0.6 and 0.4 dB at a bit error rate (BER) of 10 −10 at 200 and 400 GHz, respectively.

“…This allows companies to evaluate their future implementation in the networks serving users without affecting availability. [10] Many companies and universities have wanted to implement a laboratory and scenarios of GPON networks either for their operators or students to practice in their design and installation. Also, a lab of this type is useful for study, analysis and validation with new services.…”

Passive optical networks with gigabit ethernet speeds aim to bring internet and communications technologies using fiber optics to the end user. A test scenario for passive optical networks with gigabit ethernet speeds has been implemented. In this test scenario, practices are carried out from the installation of a manager for the administration, operation and maintenance of the active equipment, to the configuration of different types of services over this technology. Unicast and multicast traffic transport tests have been carried out. This test scenario of passive optical networks with low-cost gigabit ethernet speeds allowed simulations with different topologies and network configurations to be carried out and then transferred to real metropolitan networks. The design of the test scenario has been used to simulate the implementation of new technologies on this type of networks before they are implemented in the commercial networks of an Internet service provider. This test scenario has also been used for training in the design and implementation of passive optical networks with gigabit ethernet capabilities.

“…The default coding scheme calls for the use of (often interleaved) Reed‐Solomon (RS) codes. The main reasons for using the Reed‐Solomon codes include their relatively simple implementation, ensured error correcting capability up to a predefined number of (symbol) errors, relatively short block lengths, symbol‐oriented correction (of importance if a modulation code such as an 8B/10B code is used [35]), and the ability to correct burst errors, especially when using interleaving across multiple code words [34, 85, 91]. Such interleaving is useful for channels with burst errors and it also lowers the processing speed of the individual decoders.…”

Forward error correction (FEC) techniques are essential for optical core and optical access networks. In optical core networks, the emphasis is on high coding gains and extremely low output bit error rates, while allowing decoder realizations to operate at a throughput of 100 Gb/s and above. Optical access networks operate at 10 Gb/s or above and require low‐complexity FEC codes with low power consumption. Coherent optical transmission with higher order modulation formats will become mandatory to achieve the high spectral efficiencies required in next‐generation core networks. In this paper, we provide an overview of these requirements and techniques, and highlight how coding and modulation can be best combined in optical core networks. We also present guidelines for modulation and low‐complexity FEC system design for optical access networks. © 2013 Alcatel‐Lucent.
