Optical Crosstalk in Fiber-Radio WDM Networks

This paper investigates the impact of optical crosstalk in fiber-radio systems incorporating wavelength division multiplexing. (WDM). We present a simple analytical model that allows the impact of optical crosstalk in such networks to be assessed and validate the results via experiment for both in-band and out-of-band optical crosstalk. We show that crosstalk-induced power penalties in fiber-ra...

Ultra High Transmission Capacity of Undersea Optical Fiber Cables for Upgrading UW-WDM Submarine Systems

This paper has proposed ultimate optical transmission of ultra multi transmission channels huge submarine cables has been investigated under different depth conditions. Conventional forward Raman amplification technique is considered taking into account the reduction of the four wave mixing (FWM). The double impact of both ambient temperature and pressure effects are also investigated. The tran...

Hybrid Raman/Erbium-Doped Fiber Amplifiers for WDM Transmission Systems

As light pulses propagate along the optical fiber, their energy dissipates. Beyond a certain distance the number of photons in pulses becomes too small to be detected. The optical pulses in fibers are energized by utilizing optical fiber amplifiers. The rapid growth of the internet and data traffic in optical fiber communication networks has stimulated the study of wideband optical amplifiers. ...

Downstream Transmission in a WDM-PON System Using a Multiwavelength SOA-Based Fiber Ring Laser Source

We have demonstrated the application of a multiwavelength fiber ring laser as a cost-effective light source for wavelength-division-multiplexed passive optical networks for the first time. The performances of the system for downstream signal are experimentally investigated. We have achieved error-free transmission over 17 km of dispersion-shifted fiber at a bit rate of 1.25 Gb/s per channel.
