However, building an optical fiber link is a major investment, one that is very expensive to replace. A major impairment that restricts the achievement of higher bit rates with standard single mode fiber is chromatic dispersion. This is particularly problematic for systems operating in the 1550 nm band, where the chromatic dispersion limit decreases rapidly in inverse proportion to the square of the bit rate. For the first time, to the best of our knowledge, this document illustrates a new optical technique to post compensate optically the chromatic dispersion in fiber using temporal Talbot effect in ranges exceeding the 40G bit/s. We propose a new optical post equalization solutions based on the self imaging of Talbot effect.

Polling model has effective impact over performance investigation of network related applications. To date, the polling models have been extensively studied and analyzed only with Poisson traffic distributions. Also, in terms of providing guaranteed QoS to the end-user of multiservice Internet, a variety of scheduling schemes have been introduced in the market such as Priority Queuing (PQ), Custom Queuing (CQ), Weighted Fair Queuing (WFQ), Class Based Weighted Fair Queuing (CBWFQ) and Low Latency Queuing (LLQ) etc. All these schemes somehow represent some sort of polling mechanism in which a single server serves multiple queues in a cyclic fashion according to a specific scheduling logic. To date, the researchers have been analyzing the polling models and scheduling schemes separately. The novelty, this study brings in the area of polling models is twofold. First, we analyze different kinds of polling schemes (exhaustive, gated and combination of both) with realistic traffic distributions i.e. self-similar and long range dependent. Second, in our recent work, we have found that the combination of traditional polling schemes (exhaustive, gated and limited service) with common scheduling schemes such as priority can offer a differential treatment in terms of providing the required QoS to different kinds of applications found in modern 4G wireless networks.
