Today's data-centric networks are becoming progressively dynamic with re- spect to the transported traffic volume, to the spatial and temporal variations of traffic patterns, and to the subsequent interconnection request patterns. Optical packet routers (OPRs) aim to provide a viable answer to these require- ments by rendering the optical layer adaptable, reconfigurable at will, and cost-effective by means of statistical

ABSTRACT Passive optical networks (PONs) are being aggressively pursued as a means of delivering access network solutions. The cost benefits resulting from a reduction in the number of interfaces between nodes has enabled increasing deployment of a PON delivering fiber to the home and fiber to the curb. However, in many cases, the need for high split ratios or an extended-reach requires amplification to overcome additional losses. Erbium-doped amplifiers have a limited use in PONs since the operational wavelengths typically include backhaul at 1.3 mu m. Semiconductor optical amplifiers (SOAs) offer a cost-effective solution with a migration path toward integration; deployment options include its use as a preamplifier, booster, or midspan amplifier. We present a theoretical treatment that analyzes the amplified system operational requirements and justifies this analysis through the experiment. The analysis considers for the first time to our knowledge the dc offset that is introduced into the receiver as a result of the significant amplified spontaneous emission powers present in amplified PONs, where filter widths are typically 20 nm or greater.
The use of forward error correction (FEC) codes in future deployments of access networks is quite foreseeable and requires an analysis of the proper code for this purpose. Therefore, an overview of the most important classes of FEC codes... more
