Non-intrusive polarization dependent loss monitoring in fiber-optic transmission systems
نویسندگان
چکیده
A method for non-intrusively monitoring the polarization dependent loss (PDL) of an installed fiber-optic transmission system is proposed using live dense wave division multiplexing (DWDM)-based traffic as the probing signal. The method extracts the statistical parameters of system PDL from the measured partial PDL data. Field measurements of PDL were performed on long-haul DWDM systems deployed in Sprint’s network and the results validated our theoretical model. 2008 Elsevier B.V. All rights reserved.

Compensation of polarization-dependent loss in transmission fiber gratings by use of a Sagnac loop interferometer.
We analyze the transmission characteristics of a Sagnac loop interferometer containing a polarization-dependent loss element and lossless polarization-converting elements by use of Jones matrices. We show that polarization independence in the transmission mode can be achieved in such a configuration and that maximum transmittance occurs when a half-wave plate is used for the polarization-conver...
متن کاملPMD and PDL monitoring of traffic-carrying transatlantic fibre-optic system
Introduction: Polarisation mode dispersion (PMD) is an important factor in the performance of long-distance high speed optical transmission systems. There is clearly a need for a practical approach that supports the network provider’s planning and route design process for possible capacity upgrading in existing fibre plants, such as to retrofit 10 Gbit/s dense wave division multiplexing (DWDM) ...
متن کاملPDL-impaired coherent optical communication systems: BER vs information-theory limit
In coherent optical communications, PDL is one of the major linear impairments that can seriously impact systems performance. From an information-theoretic point of view, said PDL has to be analyzed through the so-called outage probability. After deriving this outage probability in closed-form expression for various statistical PDL models, we check these models’ accuracy numerically against a p...

The topic of thesis is “Compensation of Polarization Mode Dispersion (PMD)” in Fiber optics communication and its impact on high speed data transmission. The work can be divided into three parts which deals with major aspects of PMD: characteristics, transmission and compensation. Polarization-mode dispersion (PMD), in single-mode optical fibers, is a phenomenon that a limit the bit-rate-distan...
متن کاملAn optical implementation of a space-time-code for enhancing the tolerance of systems to polarization dependent loss
We propose a new space-time coding scheme designed to increase the tolerance of fiber-optic communications systems to polarization dependent loss (PDL). A notable increase in the tolerable amount of average link PDL is achieved without affecting the complexity of the overall optical communications link. Other advantages include seamless integration with the broadly deployed blind equalization m...
