The ability to transmit signals with high information spectral density (ISD) using low-
complexity and cost-effective transceivers is essential for short-and medium-haul optical …

Direct detection transceivers offer advantages, including low cost and complexity, in short-
and medium-haul links. We carried out studies seeking to identify the signal formats which …

A novel multilevel modulation format based on partial-response signaling called Absolute
Added Correlative Coding (AACC) is proposed and numerically demonstrated for high …

The performance assessment of a novel multilevel modulation format based on partial‐
response signalling called absolute added correlative coding (AACC) by numerical …

In this presented work we compare the duobinary and Modified Duobinary (MDB)
modulation in both Return to Zero (RZ) & Non Return to Zero (NRZ) cases at 40Gbps single …

Advanced modulation format is a promising solution to accomplish improved bandwidth
exploitation for quality transmission in optical networks. This paper proposes a modified …

We demonstrate the transmission of a 100G superchannel, composed of 4× 28-Gb/s
duobinary subcarriers placed on a 25-GHz grid, over 580 km of SSMF with three 25-GHz …

The core of the global telecommunication network consists of wavelength division
multiplexed (WDM) optical transmission systems. WDM is the technology of choice as it …

We demonstrate the successful transmission of a direct-detection 100G super-channel over
1500 km of non-zero dispersion-shifted fiber in a dispersion managed link configuration. The …

The demand for high speed data transmission is increasing so as to fulfil the demand of high
speed the Duo-binary modulation Format is used. Hence this paper deals with the duo …
