The current status of lithium-niobate external-modulator technology is reviewed with
emphasis on design, fabrication, system requirements, performance, and reliability. The …

There has been a recent surge in interest for optical satellite communication (SatCom)
utilizing lasers. It is clear to see why, as optical SatCom is capable of higher speed, lighter …

In this paper, simulative analysis of 40Gb/s long haul (500–2000km) DWDM system with
ultra high capacity upto 1.28 Tb/s has been carried out for carrier-suppressed return-to-zero …

We show that pulse-to-pulse interaction at 40 Gb/s can be reduced by alternating the optical
phase of adjacent bits by using either a modified-duobinary return-to-zero (RZ) modulation …

Analytical formulas for the power spectra of return-to-zero (RZ) optical signals generated by
Mach-Zehnder (MZ) modulators are derived. Pulse duty cycles of 33%, 50%, and 67%, in …

In this work, various dispersion compensation methods are designed and evaluated to
search for a cost-effective technique with remarkable dispersion compensation and a good …

In this paper, we investigated the performance of multi terabits DWDM system consisting of
hybrid optical amplifier RAMAN-EDFA for different data format such as non-return to zero …

In this paper, a digital transmission scheme protected by a packet-level forward error
correction (FEC) coding technique is proposed for optical feeder links in a satellite …

The paper presents a comprehensive analysis of a 40 Gbps Dense Wavelength Division
Multiplexing system with 32 channels, spaced at 50 GHz. The design has been optimized for …

In this paper, an ultra high capacity optical system with transmission capacity of 1.28 Tbps
using optimized modulation format is presented. The system design is achieved by using a …
