“…A lot of work on dispersion compensation using DCF has been carried out by various authors. Alberti et al has compared a numerical verses experimental procedure of various techniques for chromatic dispersion compensation on a terrestrial 40 Gbps system and collected the data [5]. They found that combination of long amplifier spacing and surrounding with G.652 fiber, HDP with DCF gave a better result for terrestrial systems.…”

The future generation technology needs network expansion, large bandwidth capacity, and modern application development. Due to dielectric in nature, having electromagnetic immunity, having larger bandwidth, and being a lightweight cable, the demand for optical fiber has grown expeditiously. ISI (Inter Symbol Interference) hampers the performance of optical communication drastically. It induces a superabundant increment in pulse duration, rolling out in time and space engrossed by the pulse as it propagates. As the pulse propagate along the optical fiber, this spread can be so enormous that a photo detector can no longer discriminate boundaries between pulses. Due to ISI, path loss increases rapidly and causes broadening of pulses and achieving high data rates becomes difficult. To reduce the effect of ISI pulse shaping technique is used. In this paper the channeling performance of optical fiber and DCF is estimated by using different pulse generator. Here we collated the performance of APD photo diode and PIN photo diode value in terms of Q-Factor and Bit Error Rate in the eye diagram. We have used a DCF to mitigate the effect of dispersion produced in the channel.

“…As soon as transmission bit rates increase from 10 to 40 Gbps and beyond, chromatic dispersion compensation becomes a critical issue on all kind of fibers, and the periodic dispersion compensation for 40 Gbps terrestrial systems has been investigated, with a new method being proposed on highly dispersed pulses to provide the evidence that the position of dispersion compensating devices can be placed all at the end of the system [2]. Pizzinat et al further analyzed these techniques using computer simulations [3].…”

ABSTRACTWhen updating the 10 Gbps optical transmission system to 40 Gbps, the main limits are chromatic dispersion, nonlinear effect, especially the interactions of dispersion and intra-channel nonlinearity. To optimize the performance of standard WDM in a 40Gbps four-channel transmission system, numerical simulations are carried out to comparing three different dispersion compensation techniques (without compensation; periodic dispersion compensation at the front end; and dispensation compensation all at the end of the system by means of highly dispersed pulses) for chromatic dispersion on a terrestrial 40 Gbps system. Both the loss and dispersion of the transmission fiber are periodically compensated, since two dispersive elements are placed at the input and the output ends of a compensation period. Due to the interplay between dispersion, nonlinearity and signal power, and the effect of dispersion on the pulse evolution, the pulse compress can be optimized and the system performance can be improved to compare with the system with either pre-or post-dispersion compensation. On comparing pre-and post-compensation methods, it is found that the lateral is superior to the former. Further performance optimization includes how to properly match the EDFA power and length of the fiber.

“…Furthermore, due to traffic growth and to the ever-increasing number of accomplishments within 40-Gbit/s field trials, we believe that future telecommunication transport networks, especially those operating over wide geographical areas, will be based on N × 40 Gbit/s transmission systems [4], even though the network design in this environment requires many ingenious contrivances [5][6][7]. Recently, several experiments have shown how different processes and materials can be exploited to achieve wavelength conversion [8,9].…”
