Performance Analysis of a High-Speed Optical Transmission System Using Various Pulse Generator

Abstract

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.
