This paper investigates the performance evaluation and enhancement of optimization
techniques for digital pulse-position modulation (DPPM) and on–off keying (OOK) …

In the past decade optical network is growing very rapidly due to the low noise, less bit error
rate as well as bandwidth utilization of the network. In this paper explored the bandwidth …

In traditional optical communication, duplexity is achieved by using two fibers, each with a
transmitter and a receiver. Economically, bidirectional wavelength division multiplexing …

A possible approach to maximize the data rate per wavelength, is to employ the high
spectral efficiency discrete multitone (DMT) modulation. The work presented in this thesis …

This paper presents a broadband optical packet generation method by multiplexing low-and
high-frequency signals using a bias tee. The cut-off frequency of the bias tee, fc is optimized …

This paper proposes a novel scheme that can efficiently reduce the energy consumption of
optical line terminals (OLTs) in time division multiplexing passive optical networks (PONs) …

Optical nonlinearities give rise to many ubiquitous effects in optical fibers. These effects are
interesting in them and can be detrimental in optical communication. In the Dense …

This paper investigates the implementation of a dense wavelength division multiplexing
(DWDM) 32× 40 Gb/s (1.28 Tb/s) free-space optical (FSO) communication system. The …

Today, the popularity of peer-assisted music-on-demand (MoD) has increased significantly
worldwide. This service allows users to access large music library tracks, listen to music, and …

Dynamic wavelength bandwidth assignment (DWBA) in hybrid TDM/WDM EPON is a
challenging and important issue. Normally, the ONUs located at different distances away …
