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...
متن کاملAdjacent crosstalk suppression in a colorless WDM passive optical network.
We propose and experimentally demonstrate a novel wavelength-division- multiplexed passive optical network (WDM-PON) scheme for the suppression of adjacent crosstalk arising from the wavelength misalignment in arrayed waveguide gratings (AWGs) between a central office (CO) and a remote node (RN). The adjacent crosstalk suppression is achieved by allocating two different bands to adjacent channe...
متن کاملCoherent and Incoherent Crosstalk in WDM Optical Networks
The impact of coherent and incoherent crosstalk on an optical signal passing through optical cross-connect nodes (OXC’s) in wavelength division multiplexing (WDM) optical networks is studied, and the analytical expressions are given. Such crosstalk will be generated when the optical propagation delay differences of optical paths in an OXC do not exceed the coherent time of the lasers. While cau...
متن کاملCommunication Protocols for SCM-WDM Networks
Subcarrier wavelength-division multiaccess (SCM-WDM) networks have many features, such as high system capacity, flexible packet switching access and very fast tuning speed of RF local-oscillator, etc. Though, generally speaking, existing protocols for WDMA networks can be applied to SCM-WDM networks, the transmission efficiency in terms of packet delay and network throughput is low, since an op...
متن کاملStimulated Raman Scattering and Cross Phase Modulation Analysis for Optical Networks
In optical wavelength-division multiplexing (WDM) systems, if the number of users are increased, the crosstalk becomes more severe due to imperfections in the optical passive networks and nonlinear effects in the optical fiber. In this research paper Stimulated Raman Scattering (SRS) and Cross Phase Modulation (XPM) are studied as the source of nonlinear degradation in the multichannel system. ...
